When I create a new Java Project of type Java EE -> EJB Module, the created nbproject/project.properties contains a line like "source.root=src".

When I have appropriate sources for an EJB Module (but no NetBeans project), I use New -> Java EE -> EJB Module with Existing Sources instead. In this case, the structure of the created project.properties is a little bit different, and the most important fact is that "source.root=" is not defined.

This difference does not harm the normal project management features of NetBeans (so most users will never notice the difference).

But I have tried to create a new JAXB Binding (New -> XML -> JAXB Bindung) in this project, which always failed due to problems when loading the given XSD schema file. 

After hours of debugging I found that the JAXBWizardIterator uses org/netbeans/modules/xml/jaxb/util/ProjectHelper.java for relative path calculations, and the ProjectHelper calls 

  getProperty(prj, AntProjectHelper.PROJECT_PROPERTIES_PATH, PROP_SRC_ROOT)

which is in fact 

  getProperty(prj, "nbproject/project.properties", "source.root")

Because the JAXBWizard does not expect this property to be missing, this finally results in a NPE, and the JAXBWizard will not create the binding.


Maybe this can be fixed in the JAXBWizard, but I am not sure whether or not other NetBeans feature also expect an entry "source.root" in the project.properties, so I guess this issue is better fixed when creating a new EJB Module with Existing Sources.
