I am getting the above while accessing a web service through my JAX-WS client. I know its a version problem. I have used the endorsed feature. No success with that. The real frustrating thing is that the client works fine as long as it's a Java project but in web projects it gives the above error. I have to use the client in my Struts web client project. I packaged the woking java web service client as jar and put it in my Strts web client lib. Now when I access it, I get the error.
