Description wobster 2010-01-28 06:36:18 UTC 
I have a number of existing projects that have leveraged the JAXB generation capability in NetBeans. When I upgraded to 6.8 I noticed that the JAXB generated code will not compile since NetBeans apparently is using an internal version of JAXB (2.2) compared to the compiler that must default to using the version that is in the JDK. The compile error is related to a new "required" attribute in the XmlElementRef annotation:

@XmlElementRef(name = "Test", namespace = "http://www.mycompany.com/schemas/MySchema", type = JAXBElement.class, required = false)

The only way I've seen to fix it is to import the JAXB 2.2 libraries and then add 
the -Djava.endorsed.dirs=projectpath/lib/jaxb parameter to the compiler arguments.

I would rather use the JDK 1.6_17 or 18 version of JAXB so I do not have to bundle another version of JAXB with my applets and JEE projects. 

I've also noticed that if I don't import the JAXB libraries that the Ant task is not defined outside of NetBeans when compiling using ant from the command line. I realize that Sun has not bundled the Ant task with the JDK so it might be nice to allow just the jar that contains the Ant task to be bundled, but only used for compilation and not run time. It should not be bundled with the run time in the dist directory.

Please let me know if there is a way to force NetBeans to use the JDK's version of JAXB.

I expect this happens only to old projects containing JAXB bindings.
In new projects, we specify 
endorsed.classpath=\
    ${libs.JAXB-ENDORSED.classpath}

in order to avoid the compilation and execution problems you can set up this property manually.

To force projects using JAXB version from JDK, please replace :

jaxbwiz.xjcdef.classpath=${libs.jaxb.classpath}

to 

jaxbwiz.xjcdef.classpath=//classpath to com.sun.tools.xjc.XJCTask(related to JDK version)

... and Clean & Build the project

Also remove (or comment out) the endorsed.classpath property, if present:
 
# endorsed.classpath=\
#    ${libs.JAXB-ENDORSED.classpath}

Note: You can also completely override "xjc-typedef-target" (xml_binding_build.xml) in build.xml.  

To fix this issue we need to set up endorsed.classpath also for old projects containing JAXB bindings.

Note, the issue was fixed already, and should be present in 6.8_patch :
