trouble with SAAJ

[jeen]

I am trying to set up a relatively simple web service using Spring WS, but am running into an error in the SAAJ classes. My environment is Java SDK 1.6, Tomcat 6.0.13, using spring-ws 1.0-rc2 maven bundles. The service is set up to use the Jaxb2Marshaller.

When debugging my webservice with a simple soap client (soapui.org) I get an error on any dummy request, somewhere during serialization of the response object stuff breaks down:

The following occurs in my catalina.out:

SEVERE: SAAJ0539: Unable to get header stream in saveChanges
Jul 23, 2007 5:43:36 PM com.sun.xml.internal.messaging.saaj.soap.MessageImpl sav
eChanges
SEVERE: SAAJ0540: Error during saving a multipart message

Corresponding stacktrace in localhost.log:

I am stumped (nor have I been able to find anything helpful through Google). If anybody has a clue as to what could be wrong (doubtless it's something simple, I am a Spring-WS newbie) that would be most helpful!

Ok, so it turns out that using Java SE (and a host of maven dependencies to get SAAJ and other necessary functionality) is not a good idea. The problem went away after switching to a Java 5 EE environment... My bad :S

Hi, I have run into similar problem. I evaluate the spring-ws and during some testing, I tested the EndpointExceptionResolvers functionality. Basically, I throwed a RuntimeException at the end of the endpoint invokeInternal(Element) method and I got this stacktrace. Google sent me here, as this place was the only result. I'm feeling lucky, I guess.

configuration:

<!-- Exception handling -->
<bean id="exceptionResolver" class="org.springframework.ws.soap.server.endpoint .SoapFaultMappingExceptionResolver">
<property name="defaultFault" value="SERVER"/>
<property name="exceptionMappings">
<value>java.lang.RuntimeException=SERVER,Invalid request bobe</value>
</property>

Any help would be appreciated.

[Arjen Poutsma]

When using Java 6, remove the xerces, xalan, and xml-api dependencies. That should do the trick.

[shaga]

Thanks for the answer.

The problem is getting really strange. At first, your suggestion worked, at least in the scenario where the invokeInternal method threw an exception. But it didn't work when the exception was not thrown - I got a NullPointerException from the XOM code. When trying to find out what was going on here I finally came to where I had begun - the dependencies are still there, everything works and i don't get the above error.

Really strange. If I find out what was (or still is) wrong, I'll post it here for the sake of the generations to come.

[enoahmedspahic]

Just remove the xerces, xalan, and xml-api dependencies. It works for me.
