What if you need to pass an object to a java method that requires it
to be cast to a different java type?

What if one java method gives me an Object back, but it is actually a
String. I have another java method that requires a String argument. Is
there a way to do that cast in jython?

I ran in to this when trying to use the Java xml-rpc library from
jython.
