Deployment/Undeployment with Ext plugins environment

I found some weird behavior when i started working with ext plugins using Liferay version 6.0.5. These problems are related to deployment & undeployment of ext plugins.I thought it might be helpful to beginners of new liferay ext plugins.

You will be having files related to your each ext plugin under following places

Suppose for example i have created a ext plugin named "second"

1) You will be having some jars @ temp folder of your tomcat instance @ \temp\liferay\com\liferay\portal\deploy\dependencies

In my case,
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\temp\liferay\com\liferay\portal\deploy\dependencies\ext-second-ext-util-bridges.jar
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\temp\liferay\com\liferay\portal\deploy\dependencies\ext-second-ext-util-taglib.jar
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\temp\liferay\com\liferay\portal\deploy\dependencies\ext-second-ext-util-java.jar

2) You will be having jars related to each of your ext plugin @ \webapps\ROOT\WEB-INF\lib

In my case,
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\webapps\ROOT\WEB-INF\lib\ext-second-ext-util-bridges.jar
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\webapps\ROOT\WEB-INF\lib\ext-second-ext-util-taglib.jar
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\webapps\ROOT\WEB-INF\lib\ext-second-ext-util-java.jar
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\webapps\ROOT\WEB-INF\lib\ext-second-ext-impl.jar


3) xml file related to each ext plugin will be placed @ \webapps\ROOT\WEB-INF

In my case,
D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\webapps\ROOT\WEB-INF\ext-second-ext.xml

4) Service file @ global class path of app server - \lib\ext\ext-second-ext-service.jar. Since this is a shared library/global class path you cannot undeploy when server is in running state.


D:\projects\liferay\rNd\liferay-portal-6.0.5\tomcat-6.0.26\lib\ext\ext-second-ext-service.jar

5) Once your ext plugin is deployed properly you may see some message some thing like below
[ExtHotDeployListener:188] Extension environment for "YOUR_EXT_PLUGIN_NAME" has been applied. You must reboot the server and redeploy all other plugin
s.


Copy the below code to a bat file, change tomcat_home according to your tomcat instance
> you need to send your ext plugin name as parameter , in my case "second"
> before redeploying stop the server & run the following command then redeploy

@echo off
set app_name=%1
if "%app_name%" == "" goto end
set tomcat_home=E:\Liferay605\bundles\tomcat-6.0.26
rmdir /S /Q %tomcat_home%\webapps\%app_name%-ext
del /S /Q %tomcat_home%\lib\ext\ext-%app_name%-ext-service.jar
del /S /Q %tomcat_home%\webapps\ROOT\WEB-INF\lib\ext-%app_name%-ext-util-bridges.jar
del /S /Q %tomcat_home%\webapps\ROOT\WEB-INF\lib\ext-%app_name%-ext-util-taglib.jar
del /S /Q %tomcat_home%\webapps\ROOT\WEB-INF\lib\ext-%app_name%-ext-util-java.jar
del /S /Q %tomcat_home%\webapps\ROOT\WEB-INF\lib\ext-%app_name%-ext-impl.jar
del /S /Q %tomcat_home%\webapps\ROOT\WEB-INF\ext-%app_name%-ext.xml
del /S /Q %tomcat_home%\temp\liferay\com\liferay\portal\deploy\dependencies\ext-%app_name%-ext-util-bridges.jar
del /S /Q %tomcat_home%\temp\liferay\com\liferay\portal\deploy\dependencies\ext-%app_name%-ext-util-taglib.jar
del /S /Q %tomcat_home%\temp\liferay\com\liferay\portal\deploy\dependencies\ext-%app_name%-ext-util-java.jar
