Installation

Installation consists of 2 steps.

1. First there must be extlet environment installed to the Liferay. This is permanent one-step action followed by restart of Liferay.
2. After the restart you can (re)deploy applications

Setting up the Extlet Environment

UPDATE: download extlet-hook.war, put into deploy directory and restart Tomcat. Thats all.

Manual installation

To install the Extlet environment you must copy the extlet-setup.jar into the WEB-INF/lib directory of the Liferay, e.g. C:\liferay-portal-5.2.3\tomcat-6.0.18\webapps\ROOT\WEB-INF\lib.

You can obtain the extlet-setup.jar or you can build your the extlet-setup on your own (please see the Source Codes page).

You need to reboot the Liferay in order to extlet-setup.jar to be loaded.

Deploying applications based on the Extlet

You can deploy applications’ war files using the same process as other Plugins. Just copy the war file into the liferay-home/deploy directory.

If the application contains changes of the Liferay core, then the Extlet tries to reload the Liferay (to perform the hot-deploy feature).

To enable the hot-deploy feature please see the Hot Deploy Feature page.

Deployment on Windows

Tomcat sometimes doesn’t unlock the jar files. For correct redeploy, there must be the antiJARLocking enabled.

To enable please edit the %TOMCAT%\conf\Catalina\localhost\ROOT.xml file and add the antiJARLocking=true attribute inside the Context tag.

Example: C:\liferay-portal-5.2.3\tomcat-6.0.18\conf\Catalina\localhost\ROOT.xml

<Context path="" crossContext="true" antiJARLocking="true">

Then restart the Tomcat.
