 byte b[] = t.getBytes(); getBytes() encodes this {@code String} into a sequence of
bytes using 
the platform's default charset.

But the XML says it's UTF-8.

Not that that's causing your problem (it's all ascii compatible 
characters) - but just saying: be careful with InputStreams :)

 return new ByteArrayInputStream(b);

     The exception persist. I added the artifact at web project and
     also checked if it was there at the lib when compiled and also
     checked at glassfish lib folder, it is at both places. I still
     can't figure what is the problem with it, it runs perfectly in my
     mock, as I said before, but is not working when invoked by web.
