I think the 2nd of those has been fixed in the trunk code and 1.2 release which is just about to become available. The other problem of how to use other message types is harder because the SCA specs only define how to do JMS text messages containing XML, and so far we haven't come up with a good flexible Tuscany specific way to provide that function. I shall have a go now at implementing something so its at least possible, but feel free to post any suggestions... ...ant
