Adrian Trenaman updated CXF-954:
--------------------------------
Component/s: Core
Affects Version/s: 2.0.1
> 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
> Components: Core
> Affects Versions: 2.0.1
> 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>
