Hi Sean,
It might be easier to run the source generator without ant to help track
down the issue/bug. Just run the source generator from the command line
as such:
java org.exolab.castor.builder.SourceGenerator -i my.xsd
Hope that helps,
--Keith

Hello, I'm trying to generate classes from a schema file. However, I'm
getting a NullPointerException (included below). I tried turning on
debugging in the castor.properties file, but the information being printed
out is not helping me find what line is actually causing the problem. Is
there a better way to trace this?
Another problem I seem to be having involves the Ant task: I had to finally
give up and unbundle the jar and re-bundle it to set the debug property to
true. I was trying to set classpathref to a class path def that pointed to
where I had the jar extracted to, and it still wasn't finding the class.
I'm sure I must be overlooking something dumb. Here is the relevant error
and config:
