EJB(Entety) communication with Orion Server

Hi all,
i try to test the Monica Pawlan's examples (Artikel: "Writting Enterprise
Applications with Java 2 SDK, Enterprise Edition")from www.javasoft.com.
There is an example (lesson 5 Adding JavaBeans Technology to the Mix) for
JSP -> Javabean -> EJB(Session) -> EJB(Entety) communication. This example
run on J2SDKEE-toolkit. all examples from (Lesson 1,2,3,4)can i run with
orion server but not this. I don't know why. I send you my codes and my
changes in orion config's. I think, the problem is in web.xml . the
codes(EJB's) are ok because they run with servlet and jsp(direct without
javabean).
If you have any other example. please send me that. i have intressted for a
communication between jsp, javabean, and ejb's with orion server.


server.xml :
<application name="l5" path="d:\java\projekte\l5\jarwarear\l5.ear" />

default-web-site.xml :
<web-app application="l5" name="l5-web" root="/l5" />


The error :

500 Internal Server Error

java.lang.NumberFormatException: null
        at java.lang.Integer.parseInt(Unknown Source)
        at java.lang.Integer.<init>(Unknown Source)
