change the layout of webdynpros with stylesheets

Hi all!

I have a question and hope somebody can help me!

We use an Enterprise Portal 6.0 on NW2004s.

We use webdynpros (abap + java) and we want to change the layout with stylesheets.

My question is where can i find the stylesheet (where are stored on the server, maybe what url is to use to call them…) and how can i change the layout of the webdynpros. (in particular webdynpros for java).

Thank you in advanced for the help!

Best regards

Thomas
