If you have portlets that were created in WebLogic Workshop 8.1 SP2 (and earlier???), you can make them WSRP-compliant by importing the project into an SP3 enterprise application. To import an SP2 project, use this procedure:
A context menu opens.
The Import Project-New Project window appears.
Note that Portal and Portal Web Project are selected.
The Import Project-New Project window reappears, this time showing the selected project path and name in the appropriate fields.
The import process begins and Copying meter appears. Once the files have been copied, you will be prompted to update your project with certain files and directories specific to SP3.
The imported project now appears on the WebLogic Workshop file tree under the application.
