Hello, I have problems installing Portal Toolkit plug-in for WebSphere Studio. I have "WebSphere Studio Application Developer Integration Edition - 5.0" and I would like to start learning about portals/portlets. I have downloaded PortalToolkit425, but when I run install.but it says "WebSphere Studio Application Developer or WebSphere Studio Site Developer is not installed." I get a bit confused - can anybody tell me what do I have to install? Thank you.
