Error Messages using the WEF JAXB Plugin

I just resolved an issue related to my plugin for WEF which generates JAXB code for easy conversion to/from IXML and I thought I'd write it up before I forget.

The error message looks something like this:

java.lang.ClassCastException: javax.xml.bind.JAXBElement incompatible with com.dsixe.jaxbgen....

This seems to be caused by a variance in the schema generated by the SQL Call builder where the topmost wrapper element is not annotated as root element by JAXB. The problem is solved by using code which looks like this:

javax.xml.bind.JAXBElement jaxbElement = (javax.xml.bind.JAXBElement)Transform.convertToObject(available, "http://com/dsixe/Roles", com.dsixe.jaxbgen.rolesTransformSchema.RowSetType.class);

com.dsixe.jaxbgen.rolesTransformSchema.RowSetType iAvailable = (com.dsixe.jaxbgen.rolesTransformSchema.RowSetType) jaxbElement.getValue(); 



We need to initially cast to JAXBElement and then use getValue() to retrieve the object. One more line of code fixes the problem.
