You use the JSP element to select a JSP file to store in the component.
For example:
/path/jspfilename.jsp
JSP files can be located:
The JSP page is also stored in the client war directory of the local rendering portlet or of the servlet or portlet that calls the JSP, if using the Web Content Manager API. For example, to render a JSP page on a local rendering portlet, you would also need to store a copy of the JSP file under was_profile_root/installedApps/node-name/PA_WCMLocalRendering.ear/ilwwcm-localrende.war
For example: /wps/customapplication;/jsp/editor.jsp
