Not very clear on your question. But if you want to see the code behind the visual "design" tab, click on the java and jsp tabs.
Also, to see all your source files, I find the file view better. Click on the files tab , under 'src' all your .java files, and under 'web' node all jsp files.
Sorry!
My english it's not very good.
I found the answer,
in the tab Files of the VWP, navigate to the node Setup and inside are the file to create the datasources and pools in the Sun server.
But my problem now it's a javax.naming.NameNotFoundException, when i try to reference my datasource. I have to add a line in any XML file? (like sun-web.xml,...)
thank's
