Re: [Resteasy-users] [External] Re: Error marshaling w/ XmlAnyElement + Element Adapter - simple JBoss 7 + RESTEasy project

[Johnson, S. [USA] <joh...@ba...>]

Thanks so much Jean-François.  I had taken that example from another site
– where they used the both JAXBElement as well as dom.Element – to add the
attribute to the label.  Is there another way to accomplish something like
this?  Since this is only marshaling my Java objects, I have a lot of
flexibility on how I structure my class.

<DISTILLED_WATER label="Distilled Water">Deer Park</DISTILLED_WATER>
<MINERAL_WATER label="Mineral Water">Mountain Stream</MINERAL_WATER>
<PURIFIED_WATER label="Mineral Water">Mr. Water</PURIFIED_WATER>

I've tested with JAXB 2.2.5, it's the same problem, so forget my previous
mail.

With the following method in LabelValueAdapter, there's no more NPE :
    @Override
    public Element marshal(LabelValue labelValueModel) throws Exception {
            Element e =
DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument().cre
ateElement(getCleanLabel(labelValueModel.getLabel()));
            e.setTextContent(labelValueModel.getValue());
            return e;
    }            


With this result :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<testModel>
<DISTILLED_WATER>Deer Park</DISTILLED_WATER>
<MINERAL_WATER>Mountain Stream</MINERAL_WATER>
<PURIFIED_WATER>Mr. Water</PURIFIED_WATER>
</testModel>
I have removed all adapter class private attributes and usage JAXBElement,
it seems there is a problem calling a JAXB marshaller inside an adapter.
JAXB marshalling is not "reentrant" ?

I had a similar problem, but the stacktrace was not exactly the same. This
NPE sounds like a jaxb-impl bug of 2.2.4 version, see
https://jaxb.java.net/2.2.6/docs/ch02.html. Version 2.2.4 is embedded by
JBoss7.1.x, you should replace jaxb-impl with 2.2.5. Can you also check in
your "crazy class path" project what
 is your version af jaxb-impl ?

I'll try to find time to check out and run your project.

Bill, thanks for the reply. Sorry for leaving out the version info ­
partially because I've tried 3 different configs.  Below is the stack
trace from JBoss AS 7.2 ­ which I left with it's included version of
RESTEasy 2.3.5.  I can also repeat this with
 3.0.6 if that's more helpful?


[Previous message was too long for the mailing list]


Here is a link to the full stack trace using RESTEasy 2.3.5.

You'll have to point out what resteasy version you are using so I can
match the line numbers in you stack trace up.
