(Sorry for the multi-post, but activity on saaj-users seems almost
nonexistent.)
I'm using WebLogic 8.1SP2, which is using SAAJ 1.1.1, I believe.
I could use some help understanding exactly the purpose and use of the
MimeHeaders argument to "MessageFactory.createMessage(MimeHeaders,
InputStream)". I'll describe the series of simple test cases I went
through, and perhaps someone could give me some background on what I'm
seeing here.
If my stream contains a message without an attachment, then the
MimeHeaders argument can be null without causing a complaint. The
result doesn't appear to be MIME-encoded.
If I then change my test case so the only change is making it add a
simple XML attachment (sending "text/xml" as the content-type of the
attachment), then I get an NPE, because it's apparently trying to read
the MimeHeaders object that I passed (which was null).
If I then just send it an "empty" MimeHeaders object (created, but no
headers added to it), that fails, saying there was no "Content-Type"
header. I'm guessing this is referring to the content-type of the
entire message, and not the attachment.
Then, if I add a header for "Content-Type" ("text/xml") to the
MimeHeaders object that I passed, then it appears to be fine. I wrote
out the resulting SOAPMessage to a string, and I see that there is a
"Content-Type" header in two places in the MIME-encoded message, one at
the "top", and one associated with the attachment.
In our actual code base, I have code in an "intermediary" web service
that takes a stream representing a SOAP request, but it is presently
passing "null" for the MimeHeaders argument. Will that break as soon as
someone sends a SOAP request that has an attachment?
In summary, I could use a little more understanding of the real purpose
of that MimeHeaders argument, and how it is used both with and without
the presence of attachments.
