I found the method "addLoadedImport" in the class "ontModel.class" of the jar
jena.
Can someone help me, please?Thank you in advance.
Your exception trace does not show any use of Jena code, you need to ask
the people who wrote OWLSProfileParse.
If you are getting NPE at the line
ontModel.addLoadedImport(URI);
then that means ontModel is null. Jena is not getting called.
