Ok here is what worked successfully inside an applet:
---------------------- BEGIN ----------------------------
XStream xstream = new XStream(new PureJavaReflectionProvider(),new
XppDriver(),
new ClassLoaderReference(UtilIO.class.getClassLoader()));
xstream.registerConverter(new
JavaBeanConverter(xstream.getMapper()));
----------------------- END -----------------------------
Where UtilIO is just a random class in my code. At one point I made the
mistake of passing in Reader.class which caused weird class not found
exceptions to be thrown.
I would recommend adding that somewhere to the tutorial since the default
doesn't work in Applets. Thanks again for the help!
