Web Service calling RPGLE Service PGM

 Has anyone created a web service in house for receiving say a soap 
message with an XML  document embedded and interact on that XML Doc via 
RPGLE. 
Just curious because just starting the project and like everyone knows 
an XML document has no set length and with integrating a Web Service 
with RPGLE (Service Program) my max length is 65535 for a character 
parm... 
Well from all the documentation in WDSC and on the web you create a 
java program that actually calls an RPGLE Service program passing the 
parms which in this case is an actual XML Document.  I even called 
iSeries support because i did not like the idea however thats what they 
tell me i have to do...  Thats why i am trying to find out from others 
if anyone else has had this type of project to do. 
Just wondering if anyone else has needed to create a web service in 
house for outside clients to access using RPGLE and how they dealt with 
some of these issues. 
Thanks-john
