Hi Everyone,
In my application when I call a web service it thows following excecption. I
assume this is the same exception which is talked about in this issue. If so
please tell in which release of Axis or AXIOM this issue is fixed.
Thanks

> AXIOM parser's throwing NullPointerException if OMElement.getParent() is
> instance of OMDocument and Rampart is engaged
> ----------------------------------------------------------------------------------------------------------------------
>
> Key: AXIS2-3195
> URL: https://issues.apache.org/jira/browse/AXIS2-3195
> Project: Axis2
> Issue Type: Bug
> Environment: Windows XP SP2, Axis2 1.2, Tomcat 6.0.13
> Reporter: Christopher Weiss
> Assignee: Ruchith Udayanga Fernando
> Attachments: BugDemoConfigFiles.zip, RampartBugDemo.zip
>
>
> Please see attached project to demonstrate the issue. With the axis2-1.2
> release and earlier, the AXIOM parser throws a NullPointerException when
> processing requests using Rampart:
> Thread [main] (Suspended (exception NullPointerException))
> OMStAXWrapper.updateNextNode() line: 981
> OMStAXWrapper.updateLastNode() line: 950
> OMStAXWrapper.next() line: 913
> StAXSOAPModelBuilder(StAXOMBuilder).next() line: 111
> SOAPEnvelopeImpl(NodeImpl).build() line: 469
> SOAPMessageImpl(DocumentImpl).build() line: 476
> Axis2Util.getDocumentFromSOAPEnvelope(SOAPEnvelope, boolean) line: 107
> RampartMessageData.<init>(MessageContext, boolean) line: 146
> MessageBuilder.build(MessageContext) line: 56
> RampartSender.invoke(MessageContext) line: 59
> Phase.invoke(MessageContext) line: 382
> AxisEngine.invoke(MessageContext) line: 522
> AxisEngine.send(MessageContext) line: 655
> OutInAxisOperationClient.send(MessageContext) line: 237
> OutInAxisOperationClient.execute(boolean) line: 202
> EchoStub.EchoOperation(OMElement) line: 127
> Client.main(String[]) line: 47
> The cause of the exception is the AXIOM parser's setting the boolean variable
> needToThrowEndDocument in the DOMStAXWrapper to true if the current node
> being parsed has a parent node of type OMDocument..
> Temp fix: In the code, when creating an AXIOM compatible schema, we did the
> following:
>
> try {
> // Get the schema is it is already AXIOM compatible, or convert it if it
> isn't.
> OMElement schema = docSchema instanceof OMDocument ? (OMElement) docSchema
> .getDocumentElement() :
> org.apache.axis2.util.XMLUtils.toOM(docSchema.getDocumentElement());
>
> // Workaround to fix an issue with the building the OMElement if the
> // parent is an OMDocument. Detach the element from the parent Document...
> if (schema.getParent() != null && schema.getParent() instanceof OMDocument)
> {
> schema.detach();
> }
>
> elementList.add(org.apache.axis2.databinding.utils.Constants.OM_ELEMENT_KEY);
> elementList.add(schema);
> } catch (Exception e) {
> throw new java.lang.RuntimeException("Can't convert schema to AXIOM!", e);
> }
