Error using WebServicesAssembler to create webservice for PL/SQL-Example

Question

Hello all,
I tried to create a webservice based upon the pl/sql package emptax (Oracle Example: Boolean). The package just contains:
PACKAGE EMPTAX as
FUNCTION getTax(employeeid number, ismarried boolean) RETURN number ;
END Emptax;
JAVA_HOME, ORACLE_HOME and CLASSPATH are all set according to the manual. Now I start the WebServiceAssembler.jar with:
java      -jar C:\oracle11\product\11.1.0\db_1\oc4j\webservices\lib\WebServicesAssembler.jar
     -config C:\Daten\tmp\webservice_boolean\Boolean\config\config.xml
The config.xml looks like this:
<web-service>
     <destination-path>./EmpTax.ear</destination-path>
     <temporary-directory>./tmp</temporary-directory>
     <context>/webservices</context>
     <stateless-stored-procedure-java-service>
          <uri>/EmpTax</uri>
          <jar-generation>
               <schema>scott/tiger</schema>
               <db-url>jdbc:oracle:thin:@10.10.10.10:1521:prod11</db-url>
               <db-pkg-name>EmpTax</db-pkg-name>
               <prefix>EmpTax</prefix>
          </jar-generation>
          <database-JNDI-name>jdbc/prod11</database-JNDI-name>
     </stateless-stored-procedure-java-service>
</web-service>
The EmpTax.jar is created, containing:
- EmpTax.java
- EmpTaxBase.java
- EmpTaxBase.sqlj
- EmpTaxUser.java
- EmpTaxUser.sqlj
At the end, there appears the error:
     java.lang.Win32Process.create
     java.lang.Runtime.execInternal
     java.lang.Runtime.exec
     oracle.j2ee.ws.tools.WsAssemblerConfig
     => NullPointerException: class EmpTax.EmpTaxUser not found
The EmpTax.ear-File is not generated. I'm really stuck now. Does anybody has a hint?
Thanks in advance
Christoph

Ignore the last one. I did the example here over lunch and it works fine.

Try the -debug and see what happens.
When I run these tests, I always make sure that my PATH, and CLASSPATH are the absolute minimum. That is:
SET PATH=C:\j2sdk1.4.2_10\bin
SET CLASSPATH=.\
SET OC4J_HOME=C:\OC4J_101202
SET J2EE_HOME=%oracle_home%\j2ee\home
It may just be that the classpath that you see when you run it in debug mode is missing some of the required jars for the jpub/sqlj stuff. Verify that they are all ok.
