Christoph,
How is the attachment constructed? Is this something that is a byte[]
in the jaxb beans or is it an Image or a DataHandler or what? That may
help narrow down that cause a bit.
All we do is iterator over the attachments, write out the mime headers,
then call:
att.getDataHandler().writeTo(out);
Also, what version of activation are you using?
Assuming the latest geronimo-specs activation jar, from that stack trace,
line 90 is:
is.close()
Thus, an NPE would occur there if getInputStream() returns null which
would occur if:
ds.getInputStream();
returns null. Thus, I guess I'd need to know what the DataSource is.
