Null pointer exception when prefixed XML sent to RESTful SERVCIE
----------------------------------------------------------------
Key: CXF-954
URL: https://issues.apache.org/jira/browse/CXF-954
Project: CXF
Issue Type: Bug
Reporter: Adrian Trenaman
I originally sent the following in email to cxf-dev:

Hi all,
I've been playing with the RESTful service support and I've come across some
issues that really slowed me down :( I'm describing them here (and their
workarounds) in case any users find it useful. I'm also wondering if some of
these might be classified as bugs - please advise!
Here's what happened: based on the docu in the CXF wiki User Guide [1], I
developed a RESTful service: everything was going fine until I implemented a
PUT method for an update.
--- in play/Contacts.java ---
@Put
@HttpResource(location="/people/{id}")
void updatePerson(Person person);
---
: : :
Second problem: for some reason CXF insists that the payload document's root
element is not prefixed with an XML namespace prefix. For example; the
following valid XML results in a server-side NullPointerException.
<ns2:Person xmlns:ns2="http://play/";>
<age>34</age>
<email>sdfdfdf</email>
<firstName>Adrian</firstName>
<id>42</id>
<lastName>Trenaman</lastName>
</ns2:Person>
To get it to work, I had to re-jig the XML so that Person is not prefixed (see
below). I have a feeling that this problem is related to how we inject the id
parameter into the Person XML, perhaps using an unqualified X-Path like
"Person/id", but am not 100% sure.
<Person xmlns="http://play/";>
<age>34</age>
<email>sdfdfdf</email>
<firstName>Adrian</firstName>
<id>42</id>
<lastName>Trenaman</lastName>
</Person>
