Guy,

Please could you run the test again with

log4j.rootCategory=DEBUG, CONSOLE

replacing

log4j.rootCategory=INFO, CONSOLE

in <webapp>/WEB-INF/etc/ogsadai.properties

and copy me the output.
Thanks

Further to my original report, below, the log-file catalina.out shows that
the
original exception is an InvocationTargetException which is caught and
rethrown as a SystemException at line 436 of
uk.org.ogsadai.porttype.gds.engine.Task
Here's the try block from which the exception was chucked:
            try
            {
                Class[] args = {Class.forName("org.w3c.dom.Element"),
Class.forName("uk.org.ogsadai.common.Context")};
                Constructor activityConstructor =
mActivityClass.getConstructor(args);
                Context context = (Context)mContext.clone();
                context.newView(mName);
context.putAll(mContext.getView(Engine.CONFIGURATION_VIEW));
context.putAll(mContext.getView(Engine.INVOCATION_CONTEXT_VIEW));
                mActivity = (Activity)activityConstructor.newInstance(new
Object[] {element, context});
            }
            catch (InvocationTargetException e)
Any ideas?
