Errors while deploying a JAX-WS Web Service on WebSphere AS 8.5

Question

i'm trying to deploy a JAX-WS Web Service on a WAS 8.5 server installed on a *nix OS. I get the following errors:

Is WAS really trying to download the DTD frow W3C servers and fails to do this? I've no direct access to the server machine so i can't verify it directly (but i could ask). We successfully deployed the same JAX-WS web service on WAS 7.0 and WAS 8.5 on Windows systems (and we are sure WAS is not trying to download any DTDs from Internet when deployed on Windows servers).

Any idea?

Thanks, Giovanni

Answer 1

I don't know the specific answer but I have a couple of ideas to contribute.

Have you compared the EAR/WAR you deployed on Windows to EAR/WAR you deployed on your *nix install? I'll assume they are the same but the first thing I would check with that error is to make sure WEB-INF/wsdl/KeyPushTargetService.wsdl exists in your deployment artifact.

I would find it strange if WAS is trying to download the XMLSchema definition. That might point to some configuration problem with the server. If you want to test that, you could try creating another basic JAX-WS service (like a HelloWorld example) to deploy and see if you get the same problem.

As a last resort you could also try just dropping the DTD into your EAR/WAR and see if that makes the problem go away. I wouldn't use that a permanent fix but it might let you move for time being.

Let me know if any of these work out.

Answer 2

Check your runtime jar for xml parser - looks like you're having classpath issues.
