I am happy to hear that you managed to use DataMaster.

I not sure what you mean be exporting your ontology into Java code. Do 
you mean using one of the menu options from the "Code" menu?
Also, is it really hard for me to guess what causes the 
NullPointerException without further details. :(
The only thing I can think of, is that Protege has some problems 
generating Java code from the class and property names that you imported 
with DataMaster, due to the fairly complicated namespaces that 
Datamaster generates, in order to ensure really unique URIs to the 
imported classes and properties, based on the data source location and 
the method of importation.

Maybe you want to consider using the DataMaster API [1] 
programmatically, and renaming the imported classes and properties, in 
order to give them namespaces that would work with the code generator.

I hope, however, that you have been able to fix this problem in the 
meantime.

Regards,
Csongor


[1] In order to use the DataMaster API, simply include the 
datamaster.jar file, which is distributed with the DataMaster Protege 
plug-in, into your Java class path. You can also check out the source 
code from the trunk or a specific tagged version from here:
