Error when trying to run jsp on oas4081

Question

Hi there!
As many others before, I'm trying to get jsp to run on oas4081. Although I think I did everything what the docs (and the other posts here) say, I get an error.
Here is what I did:
* download ojsp.zip
* add a JServlet application
* under ENVIRONMENT VARIABLES of that app I included %ORACLE_HOME%/ows/cartx/jweb/classes/ojsp.jar
(yes, I copied the ojsp.jar to that location; there already is a jservlet.jar, and I can run servlets, so I didn't bother about adding a servlet.jar anymore, as the manual said)
* under JAVA ENVIRONMENT I added DELEGATE_SERVLET_CLASS (left) and oracle.jsp.JspServlet (right)
* under WEB PARAMETERS I added htm, html to the mime-types field
Here is what I get when accessing http://myserver/jsp_samples/hellouser.jsp:
JSP Error
Request URI: /jsp_sample/hellouser.jsp
Exception:
java.lang.IllegalStateException: Unable to determine real path from the servlet context

Looking through the other log files, I found the following in wrb.log:

Any hints would be greatly appreciated!!!

Yes I did, when I added the JServlet application and cartridge, respectively. And I don't have a typo in there...
