Steps to follow to deploy/undeploy the EXT
As we know that EXT is not hot deployable , we need to restart the server whenever it is deployed. At first time we can deploy the EXT without any prob, but when we need to redeploy or undploying the EXT following things need to be followed. 1. Stop the tomcat server 2. Delete the temp and work folder of tomcat server. It will be reside in the <tomcat-home>. Probably it can as liferay-portal-6.2.10.1-ee-ga1\tomcat-7.0.42\temp and liferay-portal-6.2.10.1-ee-ga1\tomcat-7.0.42\work. 3. Make sure to delete the JAR files created when EXT is deployed. All the jar files will be created with name prefix as ext . Jar files will be at <tomcat-home>/lib/ext it can liferay-portal-6.2.10.1-ee-ga1\tomcat-7.0.42\lib\ext. ext-*-ext-service.jar Also it can also be at <tomcat-home>/ROOT/WEB-INF/lib/ probably it can be as liferay-portal-6.2.10.1-ee-ga1\tomcat-7.0.42\webapps\ROOT\WEB-INF\lib ext-*-ext-impl.jar ext-*-e
