How to dump database perfectly?

2011-03-07T02:18:00.000-08:00

Sometimes you're requested to repair some portal function. To do that, maybe you need to test is at localhost.
Then you're provided database. This database must be dumped into database in localhost.

The common things that happened are database cannot be dumped perfectly. Maybe you found error on generate Foreign Key, or table name not existed etc.

I will explain base on these criteria.
A. Application Server: XAMPP
B. OS: Windows (XP or 7)
C. My DB Name: myportal

I installed application server in the shortest path; i.e C:\xampp

1. Open my.ini file in C:\xampp\mysql\bin
2. Then under [mysqldump] add this line
lower_case_table_names=1
3. Change max_allowed_packet to greater value
max_allowed_packet = 80M
Note: Make sure both values for max_allowed_packet under [mysqldump] and [mysqld] are same.
4. Restart mysql service in xampp Control Panel. [Click 'Stop' and then 'Start']

[Figure1: xampp Control Panel]
5. Open cmd windows. Point to bin.
cd \xampp\mysql\bin
6. Type command line to dump database
mysql -u root myportal < "C:\project\myportal\myportalbackup03072011.sql"
7. Press Enter
8. Restart tomcat server.

How to embed portlet in portlet

2011-02-17T21:16:00.001-08:00

I want to create a page with tab panel. There are three tab headers.
Under each tab header, I want content manager update content but he not deal with my tab panel script.

He only update content in each portlet which is configured.
So I embed journal content portlet in a journal content.

<div id="tabs-perolehan" class="ui-tabs-nav">
<ul class="ui-tabs-nav ui-widget-header ui-corner-all">
<li class="ui-corner-top ui-state-default ui-tabs-selected" id="tab-title-1"><a href="#tab-panel-1"><span>TENDER</span></a></li>
<li class="ui-corner-top ui-state-default" id="tab-title-2"><a href="#tab-panel-2"><span>SEBUT HARGA</span></a></li>
<li class="ui-corner-top ui-state-default" id="tab-title-3"><a href="#tab-panel-3"><span>E-BIDDING</span></a></li>
</ul>
<div id="tab-panel-1" class="ui-tabs-panel" style="display: block;">
<div id="embedded-tender">
<runtime-portlet name="56" instance="4411" queryString=""/>
</div>
</div>
<div id="tab-panel-2" class="ui-tabs-panel ui-tabs-hide">
<div id="embedded-sebutharga">
<runtime-portlet name="56" instance="4422" queryString=""/>
</div>
</div>

<div id="tab-panel-3" class="ui-tabs-panel ui-tabs-hide">
<div id="embedded-ebidding">
<runtime-portlet name="56" instance="4433" queryString=""/>
</div>
</div>

</div>

Details:
name="56"; this name belongs to journal content as stated in /WEB-INF/liferay-portlet.xml
instance="xxxx"; We can use any 4 digit number to instance.

How to embed portlet in theme? Part 1

2010-06-10T02:13:00.000-07:00

Liferay version: 5.2.3

Embedding portlet in theme means we want to put coding in velocity files. For example, I need to embed last update portlet in a velocity file named as footer.vm.

There are three steps.
1.Install portlet using Plugin Installer. Go to Control Panel > Plugin Installer > Install more portlet > Upload file. The .WAR file for last update can be downloaded here.
2.Set the instanceable properties to false. Path: ~/server/tomcat-6.0.18/webapps/last_update-portlet/WEB-INF/liferay-portlet.xml

3.Get the portlet ID. Then put this code, $theme.runtime(“portlet_ID”)

For this example, $theme.runtime("lastupdate_WAR_last_updateportlet")
Result:

Click image to enlarge. The last update status appear in the last line.

UBUNTU: ./catalina.sh: 357: not found

2010-05-24T00:05:00.000-07:00

Problem.

error: ./catalina.sh: 357: not found
Solution: Set the path for JAVA_HOME and JRE_HOME.

First, check java version. Command line: java -version
You will get this: java version "1.6.0_20"
In case java version not equal to the value as in this example, please replace
that according to your java version.

sudo vi catalina.sh

Press key Insert
Just add these two lines.

JAVA_HOME="/usr/lib/jvm/java-sun-6-0.20/bin"
JRE_HOME="/usr/lib/jvm/java-sun-6-0.20/jre"

Then press key Esc
:wq!

Note: :wq! is to quit and save.

Liferay: How to switch language

2010-05-21T02:32:00.001-07:00

To localize the language, we configured in portal-ext.properties.
The properties for language is set as shown below.

#limit the language selection.
locales=en_US,ms_MY

I need to create a bilanguage portal. For instance at least a user can choose either to read English or Bahasa or France.
The only file that control language properties is language.properties. For additional terms, we can use Language-ext_en_US.properties and Language-ext_ms_MY.properties. In liferay Community Edition, we can put these files (Language-ext_en_US.properties and Language-ext_ms_MY.properties) in ~/tomcat-6.0.18/webapps/ROOT/WEB-INF/classes/content.
The extend properties depends on languages to be used in portal.

Every places in portal need to be switched will functions as the follows.
1. Journal content will be written using FCK Editor.
2. Theme (template & layout), portlet can be configured in Language-ext_xx_YY.properties files. In my example, xx_YY are en_US and ms_MY.

For the second part above, language's switch identifier generally in this form; #language("any_term_to_change"). Let say we need to apply this to banner. So we write #language("portal.banner"). Then we translate banner term in Language-ext_xx_YY files.

Liferay: How to add more than one layout?

2010-05-20T20:14:00.000-07:00

I created template layout using plugIns SDK. Then ant inserted myportal-layouttpl with first layout with 1-3-1 (three rows with three columns for the second row). I renamed this template layout as 'mainpage'.

But for certain page, I need another layout style, let say 1-2 (two rows where the second row has two columns). The second template named as 'subpages'.

This layout TEMPLATE not included bottom part since footer part already included in portal_normal.vm.

The colored parts in the figure technically written in 1-3-1.tpl (main_page) and 1-2.tpl (subpages). The second layout template can be added like this;
Open liferay-layout-template.xml : Path ~/plugins/layouttpl/myportal-layouttpl/docroot/WEB-INF
Add this before custom tag.

Then do not forget to do ant deploy.

Liferay: Understanding the theme (Part 2)

2010-05-20T06:32:00.000-07:00

4. portlet.vm
This velocity file tell us how a standard portlet would be included in portal. It is inserted through $theme.wrapPortlet("portlet.vm", $content_include)
in portal_normal.vm

To decorate theme, we can customise css. Maybe note on css in previous entry can help for further information.

Now we understand yet template. Inside template, there is layout template. By default, bundle Liferay comes out with classic template.
This layout template can be referred in /tomcat-6.0.18/webapss/ROOT/layouttpl/custom

Liferay: Understanding the theme (Part 1).

2010-05-19T04:09:00.000-07:00

Liferay 5.2.3
--------------------------
There are a group of velocity files for template named as portal_normal.vm (core file), navigation.vm, dock.vm, init_custom.vm.
1. init_cutom.vm
In this file, we can declare all variables in portal_normal.vm
Example:
#set ($theme_name = "myportal-theme")
#set ($the_title = "Official Web")
#set ($company_name = "MySolution.Net")
#set ($company_url = "http://www.mysolution.net")

2. portal_normal.vm
This is the core / main frame for template. It can accept other velocity files with this form : #parse ("$full_templates_path/any_velocity_file.vm")
Let say we need to include accessibility part which contains functions to personalisation (change color, font size).
So we can write script for it and name the file as accessibilty.vm
To include the file in portal_normal.vm we just add a line likes #parse ("$full_templates_path/accessibility.vm")

3. navigation.vm
The default setting only allow developer develop single page. That means no children page will be passed even if there were children pages added. This is an example script navigation.vm for three layers (main page have three children pages).

Customise language in Liferay Portal.

2010-04-20T20:50:00.000-07:00

This documentation done based on Liferay 5.2.3, tomcat-6.0.18.

In our portal, we need to use two languages. Malay as Primary and English secondary language.
To localise the language, we configured in portal-ext.properties.
The properties for language is set as shown below.

#limit the language selection.
locales=en_US,ms_MY

Since Malaysia flag icon not available, we need to add the 16 x 11 icon image in
~/tomcat-6.0.18/webapps/portal-theme/images/language
manually.

It means that when we use language portlet, only two flags will appear in the porlet. We also can put the flag icon in portal theme.
Just use $theme.language() to be wrote in our template [by writing it in portal_normal.vm].

Output:

Email Notification for Announcements portlet.

2010-04-12T20:25:00.000-07:00

Configure users setting.
Go to Control Panel > Users

Edit users with assigning them Guest community, and Announcement.

Configure Server Administration (Control Panel > Server Administration)

For outgoing port, use port 2525

Then add this properties in portal-ext.properties
announcements.email.from.address=webmaster@mysolution.net
announcements.email.from.name=Webmaster

Problem statement and Solution

The current email_body.tmpl is very simple.

Sometimes, we need to modify it so that the message becomes formal (Official).
Example,

How to modify email_body.tmpl in Announcements portlet?

In liferay Enterprise Edition (Liferay EE), email_body.tmpl located in folder dependencies.
Path: ~/html/portlet/announcements/WEB-INF/classes/com/liferay/portlet/announcements/dependencies

For those who use liferay Community Edition (Liferay CE), this file can be found in liferay-portal-src-5.2.3
Path: liferay-portal-src-5.2.3/portal-impl/src/com/liferay/portlet/announcements/dependencies

Then we need to do ant deploy in ext-impl. Copy email_body.tmpl and paste in ~/ext/ext-impl/src/com/liferay/portlet/announcements/dependencies
Notes that we need to create folders announcements and dependencies if they not existed.

Go to ~/ext/ext-impl
Then run command: ant deploy

Testing an announcement.

1. Add annoucement portlet in admin page (or any page).
2. Write your announcement.

Understanding CSS in liferay.

2010-03-07T22:39:00.000-08:00

By default, CSS styles in liferay can be found in folder /css. Bundle liferay with Classic theme means that css folder path: ~/tomcat-6.0.18/webapps/ROOT/html/themes/classic.

There are few css styles file. Main css (main.css) located all styling files from the lowest to highest (in term of priority) from top to bottom.

Let say, I want to add a new css file (e.g mystyle.css). I must import this file in main.css – add this new line @import url(mystyle.css); - the styles in this new file will overwrite all styles in other files above it. For a standard practice, custom.css has the highest priority.

Sometimes, new developer understood this thing but when doing some customization in custom.css nothing changes. Why? It is because the server not refers to that changes. When developer inspected the element using firebugs, the css style reference maybe main.css or base.css only. How to overcome this problem?

For development purpose only, developer must add new properties in portal-ext.properties (/webapps/ROOT/WEB-INF/classes). The properties are shows as the following.

## FOR DEVELOPMENT PURPOSE, NEED TO REMOVE
##AT PRODUCTIONS ##

## Set this property to true to load the theme's merged CSS files
##for faster loading for production.

##

## Set this property to false for easier debugging for development.
##You can also disable fast loading by setting the
## URL parameter "css_fast_load" to "0".

theme.css.fast.load=false

##

## Set this to flase to disable the display of CSS logging.

##

theme.images.fast.load=false

##

## Set this property to true to load the packed version of
##files listed in the properties "javascript.barebone.files" or

## "javascript.everything.files".

##

## Set this property to false for easier debugging for development.
##You can also disable fast loading by setting the
## URL parameter "js_fast_load" to "0".

##

javascript.fast.load=false

##

## Set this to true to enable the display of JavaScript logging.

##

javascript.log.enabled=true

##

## Setting it to false is useful during development if you need
##to make a lot of changes.

layout.template.cache.enabled=false

##

## Disable Liferay from opening a new browser window
##everytime start the server

##
browser.launcher.url=
##

## Last Modified

##

## Set this to true to check last modified date on server side CSS and

## JavaScript. On Development purpose just set it false

##

last.modified.check=false

##

## Enabling OpenOffice integration allows the
##Document Library portlet and the Wiki
##portlet to provide conversion functionality. This is tested with
## OpenOffice 2.3.x and 2.4. To start OpenOffice as a service,
##run the command:

##

## soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;"

##

openoffice.cache.enabled=false

##

## Set the Velocity resource managers. We extend the
##Velocity's default resource managers for better scalability.

##

velocity.engine.resource.manager.cache.enabled=false

##

## The cache filter will cache content. See ehcache.xml to modify the cache

## expiration time to live.

##

com.liferay.portal.servlet.filters.cache.CacheFilter=false

##

## The theme preview filter generates a preview of the currently applied

## theme that can be used by the Dreamweaver Theming plugin.
##This is disabled by default.
##Set the "themePreview" parameter to "1" in the URL to access

## the theme preview for any page. For example, a URL can be

## http://localhost:8080/web/guest?themePreview=1.

##

com.liferay.portal.servlet.filters.theme.ThemePreviewFilter=true

CSS sprite in liferay

2010-03-04T18:30:00.000-08:00

I have six images, arranged in a row. I call these images one by one in theme. But it will increase the HTTPRequest value.

CSS Sprite technique is a way to reduce HTTPrequest by combining images and then adjust the position value for each image. It can be in horizontal (X-axis) or vertical (Y-axis).

Before using CSS sprite, the coding[2] for that images may be look like this;

And the CSS style looks like this;

After applying CSS sprite....
In this tutorial, I combined six images and named it as button.png.
I restructured my codes as shown below.

And the CSS style looks like this;

The output:

If your button image in vertical, just adjust the Y-axis in background-position (e.g background-position:0px, -70px).

MySQL: How to fix ERROR 1153 (08S01)

2010-01-28T01:47:00.000-08:00

How to fix ERROR 1153 (08S01): Got a packet bigger than 'max_allowed_packet' bytes

Mysql Server Version: MySQL-server-community-5.1.41
OS: Open Suse 11.0 (server)

I tried to dump my database to mysql and got the error as stated in entry's title above.
The default value for max_allowed_packet is 1048576 (1M). The available range for it is between 1024 to 1 073 741 824.

Firstly, I think can edit the value by using command line when I signed in to mysql.
myserver:/etc/init.d # mysql -u root -p

mysql> SET @max_allowed_packet = '16M';
(Let say I want to increase the value to 16M).

But I got nothing, 0 row affected.
Ok, just exit from mysql.

Then open file mysql under directory /etc/init.d
vim /etc/init.d/mysql
I just pasted the excerpt from mysql file.
# If you want to affect other MySQL variables, you should make your changes

# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.

Then just create a file and name it as my.cnf inside /etc.
To make my life easy, I just copied[1] mysql file and then renamed[2] it as my.cnf
Then edit[3] my.cnf file.

[1]myserver:/etc/init.d # cp mysql /etc
[2] myserver:/etc/init.d # mv mysql my.cnf
[3] myserver:/etc/init.d #gedit my.cnf

Just add these two lines:
[mysqld]
max_allowed_packet = 16M

Then save it.
Then restart[4] msql service
[4] myserver:/etc/init.d # ./mysql restart

Again, sign in to mysql, and type command
mysql> show global variables like 'm%'; (Refer to Figure 1)

Figure 1: Show global variable in mysqld.

The new value will appear in the first row. Other way to check it is by typing this command
myserver:/etc/init.d # mysql service status (Refer to Figure 2)

Figure 2: An alternative method to look at variables set in mysqld.

Solution

Make sure file permission to all files in bin (../tomcat-6.0.18/bin) directory can be executed.
Default mod: -rw-r--r--; means that the file can be read only.

Back to server directory, command line: cd ../../
Then change the file mode command line: sudo chmod 755 -R tomcat-6.0.18/*

TortoiseSVN in PC

2009-08-18T21:55:00.000-07:00

Objective
-to guide installation.
-to review how to commit a repository into working copy.

1. Download the installer from this site.

2.When installed, the new features in TortoiseSVN will appear when you pressed right-click on the Desktop.

3.Open the TortoiseSVN ---> Setting and activate the Use “_svn” instead of “.svn” directories checkbox.

4.Choose the TortoiseMerge for Diff Viewer instead of External.

5. To link the TortoiseSVN to server, right-click → TortoiseSVN → Repo-browser. Key-in the

6.The repository browser will appear.

That means if you want to browse this repository using browser, you also can but need to be authorised first. This is because the svn authorization (permission) setting has been configured.
7. Firstly, the repository contain nothing, thus the svn manager must add new folder or files in the repository.
8. After that, these documents can be checked-out to the working copy in the PC. Just right-click the right column's repository windows. → Checkout.

9.Let say, my working copy is inside the project3 folder in Desktop.

10. The working folder will have right mark; means that all documents are revised.

11.Otherwise, the red mark will appear. It means somebody already modified the file but not checkout yet. So we can know specifically which file being modified inside the working copy folder.

12.The incident in (11) above can be solved by committing the working copy. → Checkout → write the revision message.

Clone virtual server.

2009-04-16T01:16:00.000-07:00

Physical OS: Suse Linux Ent. 11.0 (SLES).
Virtual machine OS: OpenSUSE 11.0

This documentation is base on OpenSUSE 11.1

When you setup physical server, your system (in this case : xen), will built Domain-0. Inside Domain-0 you can insert virtual server as many as you wish. For the first virtual server, you must install by using CD or by getting it form any source.
The system, let say you want to develop (create) ten virtual server in your physical server, it is not economic (in term of time saving), if you use manual ways. Setting up virtual server (xen for Open SUSE 11.0) on SLES 11.0 is about ten to fifteen minutes. This is my experience doing this technical works.
So, if you can clone the system, you just copy the template of virtual server and then just adjust the IP address and its name. For xen, this template is located in the /etc/xen/images//disk0.

For example;
I already created a virtual server named as MYSVR01_01, and I want to create ten vm's named as MYSVR01_02, MYSVR01_03,.........., MYSVR01_10, MYSVR01_11.

First, to make sure you can fully duplicate the template, you must shutdown the virtual server. If you copy the template while the server is running, you should get the full copy, but at the stage to create virtual machine, you can get an error message: Kernel not found!

Ok, to duplicate this you must login as root into your system (physical system, in this example, my physical system named as MYSVR01). Then insert this command;

cd /etc/xen/images

If you check the current template, it will tell you that MYSVR01_01 already there. And inside MYSVR01_01 there is disk0. The disk0 keep all data needed to built new vm.

Then you can copy disk0 to your vm lists from 02 to 11, by using this command

list='MYSVR01_02 MYSVR01_03 MYSVR01_04 MYSVR01_05 MYSVR01_06 MYSVR01_07 MYSVR01_08 MYSVR01_09 MYSVR01_010 MYSVR01_11'

Then do this command
for i in $list; do cp -r MYSVR01_01 $i done

Then you must wait a moment until disk0 is duplicated in each vm folder.

When the work done, turn to root, by typing

cd /etc

then

cd ..

Insert command

yast2 &

And select, Create Virtual machine.

Then select 'I have a disk or disk image from an installed operating system'

Then click forward, select the OS type.

Click forward, then write your setup for new virtual machine, such as name, memory, and Disk.

Important!
For Disk, please select hardisk, and find the template disk named as disk0 in the directory MYSVR01_02.

Then click OK.

Virtual machine console will be automatically run, and until you reach the login part for that virtual machine.

After signing in, just type command yast. And the blue windows will appear.

Select Network Device and then Network Setting.
Just rename the hostname, IP Address, and other necessary data in this windows.

When you replaced all needed part, you can check the configuration by using this command:

ifconfig

At this stage, the command prompt still remain as the old name, but when you exit (command: exit), the prompt name will be changed to the new name.

Liferay 5.2.2 : How to setup username and password with 'test'.

2009-04-06T20:19:00.000-07:00

Why did you failed to sign in as usual (test@liferay.com)?
In Liferay 5.1.2 you can login as test@liferray.com and the default password also 'test'.

For the newest version that is Liferay 5.2.2, the current username is bruno@7cogs.com and password is 'bruno'. However, we can still manipulate this data to login as test@liferay.com and its password as 'test'. How?

First, we must edit file portal-ext.properties (C:\liferay\tomcat\webapps\ROOT\WEB-INF\classes). If the file not exist, just create it by using write editor (example: notepad), and save it as ' portal-ext.properties'. Inside this file, you must put these values.

default.landing.page.path=/web/guest/home

locales=en_US, ms_MY
# the term of language can be set as your own.

locale.default.request=true
theme.css.fast.load=false
javascript.fast.load=false
layout.template.cache.enabled=false
velocity.engine.resource.manager.cache.enabled=false
theme.shortcut.icon=infra.png
company.default.web.id=skali.net
#this id also can be renamed or just keep it as liferay.com. In my case, I will use the domain name as skali.net, but the username and passwoord remain as 'test'.

#after /localhost, you can use any database name. And all data will be populated in your database.
jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://localhost/liferay?useUnicode=true&characterEncoding=UTF-8&useFastDateParsing=false

#this is the username and pasword to access your mysql database.
jdbc.default.username=root
jdbc.default.password=root

schema.run.enabled=true
schema.run.minimal=true

How to customise your page? That means we dislike to see previous works from 7cogs.
Ok, just remove folder sevencogs-hook in the webapss. (C:\liferay\tomcat\webapps).
Restart your liferay server. (statrup.bat / startup.sh – depend on your system platform.)

Then your page will be like this. See figure below.

Still have problem with Sevencog Theme?

Open Source Review

2009-03-09T19:24:00.000-07:00

Nowadays people in IT or ICT companies like to talk about Open Source. It is a good practice to use open source software as an alternative to reduce budget. In Malaysia, the phrase of 'Open Source' turned to a popular term when MSC or next to be MSC company impelement it to their operation. There're many reports that support its usage. Open Source Master Plan by MAMPU is the influenced and authenticate party to support this matter. Somehow, there is a 'war' between open source and free software. You can refer this article to understand the scenario.
