Hi, I’m
an axis newbie and having trouble sending an image attachment (document style
message) from my client to the server. The attachment seems to go across fine,
but when I use AttachmentPart on the server, the
server hangs. It tries to write the
binary source to the console/screen and the PC beeps endlessly, and it hangs. I’ve been at this for ten days now
trying to figure out what the problem is. No one at work has much experience with
axis so I’m on my own on this one.
Any tips whatsoever on what it is I’m doing wrong would be very
much appreciated. I’ve
attached the following files: RemoteTaskResultService (client-side), RemoteTaskResultImpl
(server-side), remotetaskresult (wsdl) I’m
using Axis 1.1, Tomcat 4.1.x Thanx a million |
