Hi I try to run schemaExport task directly from example in "hibernate quickly" book and it doesn't work.
I also tried with exapmle from wiki about schemaExport but I got the same:

Why this exception isn't caught and translated to readable state?
NullPointerException doesn't tell me much, all the more source code for that place is:

return new SchemaExport(cfg)
.setHaltOnError(haltOnError)
.setOutputFile( outputFile.getPath() )
.setDelimiter(delimiter);


Hibernate version:3.1

BUILD FAILED
