Hello everybody:
I am trying to use Ant Task programmatically by invoking the API within my
Java code.

I get an exception, but everything appears to be fine to my eyes - I indeed
set all the compulsory attributes of the SignJar task. Probably somebody
else here has a good suggestion or the solution.

Thanks in advance!

Dan

----------------------------
My code is:

        String sigFile = Paths.SIG_FILE_PATH;

        SignJar sj = new SignJar();

        sj.setAlias("myDep");
        sj.setStorepass("aPassword");

        sj.setJar(new File(fileName));
        sj.setSigfile(sigFile);

        sj.execute();

The exception I get is:

Exception in thread "main" java.lang.NullPointerException
