Java.lang.LinkageError while deploying.

Question

Hello All,
I am working on an application which runs on jboss and while deploying I come accross the below error.
09:55:37,607 ERROR [[ehaweb]] Servlet.service() for servlet ehaweb threw exception
java.lang.LinkageError: loader constraint violation: when resolving interface method "com.eha.service.PageAccessMangementLoca
l.savePageAccessLog(Lcom/eha/domain/PageAccessLog;)V" the class loader (instance of org/jboss/web/tomcat/service/WebAppClassL
oader) of the current class, com/eha/web/filter/PageAccessLogFilter, and the class loader (instance of org/jboss/mx/loading/U
nifiedClassLoader3) for resolved class, com/eha/service/PageAccessMangementLocal, have different Class objects for the type c
om/eha/domain/PageAccessLog used in the signature
Please let me know if something else is needed.
I am deploying an ear file which also has a war file and all required libs and jars in it.
Thanks in advance.

First of all thanks for the reply,
Your reply resolved my issue but now I am facing different error at deployment as given below.
15:55:05,833 ERROR [ContextLoader] Context initialization failed

My EAR structure is like this,
EAR
-meta inf
-jar's
-war
- web inf
- classes
- lib
The classes in war's "classses" directory needed to access some classes in jar's of ear's root directory.
since I had first bundled these jars again in lib directory of war's web inf, I deployed it sucessfully but at run time
It gave me previous errors that was solved by first reply (due to duplicate jars), now since I have deleted those
duplicate jars, It gives me above error.
Please help, I have stuck here for a long time now.
