Subject Re: Error getting attachments from SOAPMessage
Date Wed, 07 Jan 2009 22:42:23 GMT
See my comments inline.

I also committed my test cases to axis2-saaj (see MessageFactoryTest).
Obviously, since they don't pass yet, there are commented out. Can you
uncomment them and check your modifications against them?

Your code should set the contentId property, but it should add the
angle brackets.

Strange. Can you post the full stack trace?

I think that it unnecessarily copies data around.

I don't think that one can expect that the getName information be
preserved (where would this information be stored in the message?).
Obviously the content type should be preserved. I will have to
investigate this.
