RE: User Guide: Code generation for client

[Derek]

Title: Message

Hi, folks.

 

While I'm flattered to hear that you might think I know what is going on, I'm afraid you are sadly mistaken. :-)

 

Actually, I'm not an Axis developer. I'm just a rather frustrated user, like yourself, who is maybe a bit more verbose than most because I try to ensure that people actually report the bugs in Axis to JIRA so that they get fixed. (Developers typically don't try to fix bugs unless they actually show up in a bug tracking system, so complaining about them on the mailing list is not enough.) I don't have any special knowledge about Axis other than having tripped a bunch of times, fallen flat on my face, and having learned enough to avoid the few specific potholes that I've stepped in. As far as I can tell, your problem is not one of these.

 

As far as diagnosing a data binding error, I would try to capture the data that is being sent from client to server or back (using something like tcpmonitor) and see if the data being transmitted is something reasonable. That will at least tell you if the error is occurring in the client versus in the server. It's also possible that you might be having a problem with 'chunked' data encoding (as described by some other people on the list) screwing up your XML parsing. I haven't had this problem, so I don't know much about it. I would try to make very sure, however, that the version of Axis libraries that you are using  for your client, your server, and WSDL2Java are all exactly the same (which should preferably be the latest nightly build you can get). Version skew between these could cause a lot of problems such as data binding errors.

 

I also seem to remember there being some discussion to the effect that some of the samples in the user guide were wrong, so you might do some searches on the list to see if your problem is related to this.

 

I also recommend filing a JIRA to the effect that the error message "data binding error" that you seem to be getting is not specific enough to be useful in solving the problem. I think that any such error message generated by Axis or Axiom should at least identify what specific XML element could not be bound, and why.

Guys,

This issue being discussed seems to be against Axis2, I'd suggest that you append a prefix "[Axis2]" (without quotes) to your messages and post so that your mail lands up in the filters of the saviours :)
 

cheers

According to
http://www.mail-archive.com/axis-user@ws.apache.org/msg16725.html , which I
had overlooked before, we need to use the nightly snapshots. I still could
not get it working. Now I definitely give up and wait for the next Release
or at least for the next complete nightly build.

Good luck for the rest or you!
Marcel
