Hi all,
By accident I run into a wired issue using XMLBeans data binding: For
testing purposes I added a simple log statement in my generated InOut class
before skel.process(). Using the generated Stub class I get a
NullPointerException in XMLBeans Factory.parse() (or better XMLBeans
Cur$CurLoadContext.finish,low see b). If I remove the log statement,
everything works. What makes this error wired is that it depends on the
existence of a <SOAP-ENV:Header/> within the request. If I send a SOAP
request without a SOAP-ENV Header tag, processing will succeed. Even WITH
the log statement.
I tried to track down the reason for it, however I got lost somewhere
between finding the right version of ws-commons and the current toString
implementation of OMElement, OMNode and so on. My first impression is that
there is a caching issue in ws.commons.om.OMElement.
Shouldn't the following work (I have working example for it)?
Instead of the generated
---
Foo param3 = null;
param3 = skel.process( (Foo)
fromOM(msgContext.getEnvelope().getBody().getFirstElement(), Foo.class));
---
I used
---
Foo param3 = null;
log.info(msgContext.getEnvelope().getBody().getFirstElement());
param3 = skel.process( (Foo)
fromOM(msgContext.getEnvelope().getBody().getFirstElement(), Foo.class));
---
and got the following exception:
