A supported use case for using Ext Plugins in Liferay DXP is modifying its
web.xml file. Before beginning, make sure you’ve reviewed the generalized
Customization with Ext Plugins
As an example, you’ll create a sample Ext plugin that modifies Liferay DXP’s
web.xml file (e.g., in the
folder). You’ll modify the session timeout configuration, which is set to 30
(minutes) by default:
<session-config> <session-timeout>30</session-timeout> <cookie-config> <http-only>true</http-only> </cookie-config> </session-config>
The Ext plugin will update the session timeout to one minute.
Navigate into your Liferay Workspace’s
/extfolder and run the following command:
blade create -t war-core-ext modify-session-timeout
Your Ext plugin is generated and now resides in the workspace’s
/extfolder with the name you assigned.
ext-web/docroot/WEB-INFfolder, open the
web.xmlfile, which was generated for you by default.
Insert the following logic between the
<session-config> <session-timeout>1</session-timeout> <cookie-config> <http-only>true</http-only> </cookie-config> </session-config>
Notice that the
<session-timeout> tag has been updated to
That’s it! Now when your Ext plugin is deployed, your Liferay DXP installation will timeout after one minute of inactivity. Follow the instructions in the Deploy the Plugin article for help deploying the Ext plugin to your server.
