I can tell you exactly why it didn't find
it. getClass().getResourceAsStream("test.xml") looks for the test.xml file
in the same package as your class exists and nowhere else. If you want to
find test.xml in the root of the classpath, then do either
getClass().getResourceAsStream("/test.xml") or
getClass().getClassLoader().getResourceAsStream("test.xml")

Although I'm not sure<br>
why getClass().getResourceAsStream(testDoc); was not<br>
able to find a file that was present in the<br>
/WEB-INF/classes directory! Changing the servlet<br>
initialization code to<br>
context.getResourceAsStream("/WEB-INF/classes/" +<br>
testDoc); worked!<br><br>
Thanks again,<br>
