Please help me to figure out where i am doing mistake...

Answer 1

There is a conflict between your web service libs and tomcat's libs.
use the folowing dependecy :
<dependency>
<groupId>com.sun.xml.ws</groupId>
<artifactId>jaxws-rt</artifactId>
<version>2.2.8</version>
<scope>provided</scope>
</dependency>

Answer 2

I had the same problem.
I was using the webservice-rt-1.4 with Maven's dependency and repaired who the webservice-api jar also was coming along with COMPILE scope. Then change to PROVIDE scope in the Maven and put webservice-rt-1.4 in the tomcat.
Also check was conflicts between the XML's lib of app with the tomcat.
Hopefully this is also be the case.
Hugs!

Answer 3

In my case, it was the jaxws-rt.jar included in the war file generated for the web service which was causing the problem but once I cleaned and built the war again keeping dependency as provided, it worked fine
