This error sounds like the namespace xmlns:j="jelly:core" is being
interpreted as j="jelly:core" which is wierd. This could be a SAX parser
issue. Which SAX parser is on your classpath? Could it be a wierd, or old
SAX parser I wonder?

If you like. I tend to just use JellyContext directly...
JellyContext context = new JellyContext();
context.setVaraible("a", whatever);
...
XMLOutput output = new XMLOutput( myOutputStream );
context.runScript( "foo.jelly", output );
