Simon Nash commented on TUSCANY-3681:
-------------------------------------
As this is a Tuscany API in 1.x, it may well have limitations such as not being
able to support bindings other than binding.sca.
When I have used this API in 1.x (for example, in the travel sample) I have
worked around this problem by using an extra component as described by Scott.
This also has the advantage that the extra component can be local to the client
even though the service being invoked is remote.

> Issue Type: Bug

> Environment: JDK 1.6.0_21, Windows XP
> Reporter: Sebastian Millies

> I call a service method exposed by a JMS binding. However, at the time when
> the constructor of
> org.apache.tuscany.sca.binding.jms.wireformat.jmsdefault.runtim.WireFormatJMSDefaultReferenceInterceptor
> is executed, the inputWrapperMap argument is empty (size 0), which leads to a
> NullPointerException later on when the requestMsg is constructed in method
> invokeRequest.
> The stack trace is this:
> java.lang.NullPointerException
