Just from a quick glance it looks like the result.jsp is not quite
right. It should look like the one shown here:
http://cwiki.apache.org/GMOxDOC21/simple-web-service-with-jax-ws.html
(titled add.jsp where jndi lookup is done). See if changing that
helps.

In order to provide a simple way to recreate the problem, I modified the 2.1 webservices sample ( http://cwiki.apache.org/GMOxDOC21/developing-a-simple-calculator-web-service.html ) such that the add() method returns a String[] instead of an int.  The mods were simple, I changed the "return" element of the addResponse in the wsdl of the sample
