Hi,
Thanks (Erik) for the answer to my previous question. I am however
getting an NPE when using the Delegation Processor. The processor
successfully calls the Stateless session EJB method (which prints to the
console), but then immediately throws a NPE. I have tested the EJB
method successfully with a Java client. Perhaps the XPL is incorrect?
The EJB method signature is:
public void saveXForm( java.lang.String theform )
throws java.rmi.RemoteException;
XPL and stack trace listings are below:
Any help appreciated.
Regards, Avinder

Subject: Re: [orbeon-user] Using Delegation Processor
If you want to pass a string, you should first convert the XML instance
into a string. You can do this with the XML converter, for example.
http://www.orbeon.com/ois/doc/processors-converters#xml-converter
Then, with XSLT, build your "call" input document and embed the
resulting string.
