SEVERE: Error loading WebappClassLoader

Question

I am developing a webservice using JAX-RS RESTEasy using java.I am getting the following error(as showed inside my stacktrace). I have firstly used jersey_bundle-1.17.1 maven as described at java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer here.Before that i am used jersey_bundle-1.12.Both of them wont works.After that as per the error i have searched for com.sun.jersey.spi.container.servlet.ServletContainer package inside jarfiles and it found at there.But i am using maven and i searched inside maven and it not found at there(But i added those to my pom.xml).Is that my problem?If it is how to resolve that error?Or else what is my problem i am not getting any clue about that(Spend more than 14 hours) on it.Any help will be highly appreciable... NB:I am using tomcat-v 6.0 server

Can you please open up your WAR file and check to see if the required Jersey dependencies are there? Your POM looks fine to me. — Tim Biegeleisen, Apr 16 '15 at 06:42
TimBiegeleisen I will check it and replay. I have one more dobt.Can you please check my web.xml for checking my servelet name.especially my that i defined........That thing is showed as error inside my application.In somewhere else i found that org.glassfish.etc....contains that com.sun.jersey.spi.container.servlet.ServletContainer.I am using tomcat 6.0 — Miller, Apr 16 '15 at 06:53
Your `web.xml` looks fine. If this were a problem, you would be getting errors from trying to instantiate the `ServletContainer` class. Please check the WAR which is being deployed; I'll bet it is missing the Jersey dependencies. — Tim Biegeleisen, Apr 16 '15 at 06:59
ok Tim Biegeleisen.about getting errors from trying to instantiate the ServletContainer...thankyou.I will check my WAR and will reply surely... — Miller, Apr 16 '15 at 07:03

@TimBiegeleisen I can just see a web-inf and meta-inf while extracting war files.cannot able to see jar files inside it(I am new to web application development ). — Miller, Apr 16 '15 at 08:22
Please view [this site](http://docstore.mik.ua/orelly/xml/jxslt/ch06_02.htm) to understand the WAR structure. Open your WAR using 7-zip or a similar tool. We must determine whether or not your WAR has the required Jersey libraries. — Tim Biegeleisen, Apr 16 '15 at 08:24
@TimBiegeleisen extracted war file as the way you mentioned above.It shows classes,web.xml and library.My LIBRARY folder is empty. — Miller, Apr 16 '15 at 08:37
@TimBiegeleisen Maven is contained under my project folder(inside eclipse).So i just Right clicked Projectname>export>web>warfile>finish.Is there anything wrong?(At the begining stage i right clicked projectname and make that project as maven dependent) — Miller, Apr 16 '15 at 08:44
Please research what could be the cause of your missing dependencies. Good luck! — Tim Biegeleisen, Apr 16 '15 at 08:49
