Is "myML.html" actually in that "xmlc_on_classpath" directory or in some 
deeper directory path within that?  Also, you probably shouldn't append the 
"/".  Let's say you provide the resource path "/home/kipz/dev/someproject" 
and "myML.html is in the "com/mycompany" package.  You would load it like 
this....
xmlcDeferredParsingFactor.createFromFile("com/mycompany/MyML.html");

Note that if your "myML.html" file wasn't found, it would then default to 
loading it from the classpath.  This might be what you are 
experiencing.  The path you are providing might simply be wrong, but XMLC 
still finds the file on the classpath so it loads it instead of the one it 
couldn't find on the resource path.

Yep, but probably because you provided the wrong path to it within the 
resource path as stated above.

Hopefully that helps.  Let me know if you are still having problems.
