I’m using ActionWebService to expose a WebService of my application,  
and I would like to control the error responses sent back to the  
client.  
At very least, I would like to prevent the XML to include the  
backtrace.  
How can I do this?

I wouldn’t have thought the backtrace would be outputted in production  
mode. Have you tried running in production mode? script/server -e  
production
