Hi,

do you know, how I can send custom error messages to XML-RPC clients?  
I tried throwing an exception but then the client receives a message  
like "helma.scripting.ScriptingException: That's my message. (/usr/ 
local/helma-1.6/apps/myApp/API/Actions.js#23)" in the error object  
which is a bit too much of an insight. So, is there a way, that the  
client only gets "That's my message." ?

Thanks!
Walter
