You can create and maintain the resources for your portlet applications in portlet projects. Portlet projects can be added to a new or existing enterprise application project.
To create a new portlet project, follow these steps:
Use the 2.2 servlet version when you are creating an Empty portlet project that you intend to import a WebSphere Portal 4.x portlet WAR file into. Version 2.2 includes a Servlet Specification level of 2.2 and a JSP Specification level of 1.1. Features such as Servlet Filters and Life Cycle Event Listeners cannot be used if this level is chosen.
Note that the servlet version will determine the choice of target servers that appear in the drop-down list.
If you want accept the defaults associated with a Basic IBM® API portlet project, click Finish. If you prefer to customize the project options, or want to create a project that is enabled for a different type of portlet, click Next.
