how to create jsp page in my vaadin portlet?

Hello all,

i have been spending my last thrwee day with finding out how to connect a jsp page into my vaadin application.
I read lots of tutorial such as https://vaadin.com/de/forum/-/message_boards/view_message/1361699, https://vaadin.com/de/book/-/page/application.environment.html, http://dev.vaadin.com/wiki/Articles/JSPIntegration#no1

but it is still not working :frowning:

is there any simple source code example of JSP Integration for vaadin?

in http://dev.vaadin.com/wiki/Articles/JSPIntegration#no1 there are source code examples. But after i downloaded this source code, my vaadin application at then only show the code that is shown in the application class and the jsp was not called at all.

Please help me.
