The correct branch of the code is documented on the wiki, if you're 
trying build from source:
https://spaces.internet2.edu/display/OpenSAML/OSTwoDevManJavaBuild

Otherwise you should probably be using the released version:
http://shibboleth.internet2.edu/downloads/opensaml/java/

You should probably read up on what Serializable does, I doubt its what 
you want it to in this case.  You're looking for an answer that depends 
wholly on your environment and the tools you use.  How do you add XML to 
your SOAP service message?  However the tool you use expects you to add 
XML to the SOAP message.
