Hi, I am running Tuscany within a Tomcat web project and I am getting the following exception Caused by: java.lang.NullPointerException at commonj.sdo.impl.HelperProvider.getDefaultContext(HelperProvider.java:379) ... I am guessing this is to do with trying to return a complex type from one of my services which is being exposed over JSONRPC. In this situation do I have to use SDO or are there other, simpler options?
