Cheers Rob - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Hi Rob I came across a problem when returning SDOs from services exposed with the JSONRPC binding ( http://issues.apache.org/jira/browse/TUSCANY-1337) that is not fixed yet. In my case it was to do with returning types represented by generated SDO classes. The JSONRPC binding was struggling trying to serialize the underlying EMF classes. I wasn't getting a NPE though. As Mike says if you could provide a bit more detail of your scenario we can work out if this is the same problem or a new one. As a work round I created a class to represent the complex type manually and returned that. Regards Simon
Re: Returning complex types from a service
I don't think the problem is with the jsonrpc now actually. I have been playing around with removing services from the .composite file and the error occurs even when the jsonrpc binding is not mentioned. While making changes I started receiving a memory exception so I restarted Tomcat and now I'm getting an IO exception stating that it cannot create a directory target (trace below).

Re: Returning complex types from a service
We have partial support for a contribution repository, and that is a flag to tell contributionService to store the contribution in the repository or not.
