You're trying to mix a j2ee library with tomcat and that just doesn't
work. Consider javaee.jar to be "everything including the kichen sink"
-- lots and lots of packages all in one jar file. Some of the things
that javaee.jar provides are already provided in tomcat and you can't
have two of the same class in the classloader hierarchy. If your target
container is tomcat, drop the javaee.jar from your project then add back
in stuff that's missing using individual package implementations.
Google is your friend and you should be able to find jars to replace all
the missing functionality.

Hi Folks,
I am new to tomcat.
Currently I am learning spring-struts-jpa-ajax stuff. And deployed to
apache-tomcat-5.5.23.
(http://struts.apache.org/2.x/docs/struts-2-spring-2-jpa-ajax.html)
When I deployed war to tomcat, I got the following error:
------------------------------------------
INFO:
validateJarFile(C:\sumacadmin\out\exploded\strutsajaxWeb\WEB-INF\lib\jav
aee.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2.

Caused by: java.lang.NoClassDefFoundError:

javax/persistence/EntityManagerFactory is in javaee.jar file. How can I
fix this issue? Please help. Thank you very much !
