Error with web service standalone proxy

[Former Member]

I am getting following error when trying to consume a web service using a standalne proxy.

Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !

Error Message is :com/sap/guid/GUIDGeneratorFactory

java.rmi.RemoteException: Service call exception; nested exception is:

com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeException: Invalid Response Code: (407) Proxy Authentication Required.

Note that I tried everything, including switching off the proxy settings, setting the proxy programatically and all possible alternatives.

Interesting part is this server hosting the web service is accessible from my desktop being in the same network. I dont need proxy authentication when access it from my browser....

Any clues?

Are you using a proxy to access the server (where the web service is), from your desktop?

It could seems that your are accessing transparently through your navigator, but it can be autheticating automatically if it's using NTLM protocol.
