java.lang.IndexOutOfBoundsException in processing

Hey there,
Finally I created my SAP WebService-Call. The only problem is that the
HolderInInterceptor throws a IndexOutOfBoundsException by processing the
reply of the SAP WebService. I've enabled Outbound and Inbound-Logging to
see if the XMLs are sent correctly.
The problem accurs in HolderInInterceptor.class:67 where part->concreteName
= "ETColumnDescription".

*Index=2 and outHolders only contains one Element that is null.*

Holder holder = (Holder)outHolders.get(*part.getIndex() - 1*);


Any suggestions?


*Stacktrace:*



Cheers,
Chris

Hi,

Your code should be like

public void handleMessage(Message message) throws Fault {
        InputStream is = message.getContent(InputStream.class);
        if (is != null) {
            CachedOutputStream bos = new CachedOutputStream();
            try {
                IOUtils.copy(is, bos);

                bos.flush();
                is.close();
                bos.close();
                String soapMessage = new String(bos.getBytes());
                //change this soapMesage what ever you want and set as message Content
            } catch (IOException e) {
                throw new Fault(e);
            }
        }

    }

NOTE, this interceptor will impact the performance as it break the stream

Thanks for your help!
I've added an interceptor in thereceive-Phase but sadly the message-object
doesn't contain my XML-Stream. Is this the wrong interceptor-phase or do I
have to do something more?

Hi,

Yeah, you can always register an interceptor yourself on client side at very early stage(like Phase.RECEIVE) and change the InputStream to anything else you want.
However, the main problem here is that CXF and SAP webservice are not on same page, CXF is jaxws implementation which clearly defined how to use Holder, I'm not sure how Sap webservice handle Holder.

Jep, You've got the point. After creating a cxf-Server by myself everything
worked fine. But that doesn't solve my problem ;) Is it maybe possible to
catch the incoming xml-string and process it by myself?
Any other ideas how to bypass this issue?

Hi,

I suggest you create a CXF server and dump onwire message from CXF server, and compare it with the one from SAP webservice server.

My gut feeling is that SAP webservice may not follow the JAXWS spec about the Holder class.
