I'm a student and i do currently a practical training by IBM in germany. I learn how to programming portlet and it is new for me. i found a book in the redbooks pages that i use to learn. i have already deploy my first portlet, it was with the IBM API. i use the RAS v6 as development environment and the websphere portal v5.0 test environment. I wanted to deploy my first portlet with the JSR 168 API and for that I define a new JSR 168 portlet project. However I can't deploy these, it don't work. I become an error: action canceled. I export my project as *.war file and try to deploy it in the websphere portal 7 that i also install, but the deployment failed too.
can somebody help me?
