I have tried to exclude "javax.servlet-api " ,but with no avail .
If anyone can help me in finding the reason behind this exception ,that would be of great help .
Thanks

Made a silly mistake ,instead of using
"org.springframework.data.rest.webmvc.RepositoryRestDispatcherServlet"
,i used
"org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration"
.
Hope after seeing this post other people will not make the same mistake

CXF : java.lang.ClassNotFoundException: org.apache.cxf.transport.servlet.CXFServlet

However, the jar containing the class viz. cxf-rt-transports-http-2.7.4.jar is present inside lib directory of the WAR inside the EAR installed.
What is the cause of the issue ?
How can I resolve it ?

I see that you mentioned the word "publish", which hints that you might be using Eclipse, or possibly IBM's RAD or even MyEclipse Blue.
In case that's true, read on...
While your .ear, generated by m2e/Maven, may have the .jar file present in the .war file, there's a chance that the .ear and .war file, generated by m2e-wtp, is missing the .jar file. m2e-wtp's generated .ear file is what's used when you publish/republish your application to WAS from within Eclipse/RAD/MyEclipse Blue.
Try removing the app from your local WAS, finding the location of that m2e-wtp-generated .ear file, and deleting it. From there, m2e-wtp should automatically generate a fresh .ear file if you clean your project (all associated pom, ear, war, etc.)
When you publish your app, it should find the class. I've had the same problem happen to me in the past. My suggestion has fixed the problem.
Other than that, you may need to set the Classloader Policy to PARENT_LAST and check that you're using a single classloader for the entire app (the 2nd set of radio buttons below the Classloader Policy radio buttons) within the WAS admin console. However, I doubt that the Classloader Policy is the issue.

I'moved to jetty 7, now I have such exception: pastebin.com/ZdRXzeED

jaxrs-ri-2.4.1 expects that you run on Glassfish.
Look at this old question (and both answers) for some help.

Your .war was compiled under a newer JDK than the JRE that is available on the remote tomcat. Either install a matching JRE on the remote server or recompile your project with the correct version of the JDK.

This line should give you a clou:
java.lang.UnsupportedClassVersionError: com/shafer/server/server :
Unsupported major.minor version 51.0
(unable to load class com.shafer.server.server)
What is com.shafer.server.server? Check the versions of your libraries.

The UnsupportedClassVersionError means that the class was compiled with a more recent Java compiler than the one you are using in your runtime.
I don't know the version numbers by hearth, but you should probably use a JRE 6 or higher to run Tomcat.
