Got it! Thanks for all the help guys. Jcplerm, you're code was perfect - I messed it up and realized it after reading the CollectionsImpl.java.
I never bothered to in the CollectionsImpl.java because I grep'd for "xupdate" in those directories and it came up with nothing!
Out of curiosity, what is the relationship between the xindice xml-rpc interface in 1.1 and the xml-rpc interface for xindice 1.0 hosted on sourceforge? Are they one and the same? Will there be a use for the xml-rpc interface for 1.o when a 1.1 production release is complete?
It's very likley that these interfaces will not work with 1.1 release. The on the wire aspects of the xml-rpc driver are effectivly private. We make minimal effort to ensure that they are compatible.
-k.
