Hello, You can put your js file, for example, into a directory called "js" in your root application, then you should edit your jboss-potlet.xml file (located in WEB-INF directory, or you should create it) to include it in the header content as is showed below: | <portlet> | <portlet-name>YourPortlet</portlet-name> | <header-content> | <script type="text/javascript" src="/js/your_js_file.js"></script> | </header-content> | </portlet> | That's all.
