getJAXBNodesViaXPath Exceptions

[Julienoune]

Hello all

I have an exception when I'm trying to run the following code :

Code: Select all

Body body = (Body) main.getJAXBNodesViaXPath("//w:body", true).get(0);

Code: Select all

I've checked into the docx document if my w:body is present.

Any idea why I'v got this exception??

Environment :
Windows XP
grails-1.3.4
docx4j-2.5.0.jar
JAXB: Using Java 6 implementation.

Hello folks.

My error came from that I executed marshalling and unmarshalling on the main document part before the main.getJAXBNodesViaXPath("//w:body", true) call.

So the xpath instruction is unable to found my w:body node.
I have read about the JAXB bug about the reloading parameter.

Not a big issue, I have just moved my call to Xpath before the marshalling and unmarshalling.
Hope its helps.

Cheers.
