java - Web app with JPA doesn't work on extenal Tomcat server -

-

i've problems publishing dynamic web application in tomcat, on vps server.

i developed application contains servlet( creating entity manager , doing operations on database), , jar files - entity components packed in jar file. application uses eclipselink , postgresql.

on tomcat 7 server installed witch eclipse, works fine, when try deploy tomcat 7 server on vps i'm getting exception:

javax.servlet.servletexception: error instantiating servlet class pl.marekbury.controller.storeserver

and root cause

javax.naming.namenotfoundexception: name [pl.marekbury.controller.storeserver/persistence_unit_name] not bound in context. unable find [pl.marekbury.controller.storeserver].

i had same error on localhost eclipse-integrated server, found solution (somwere here, on stack) chcange eclipselink version, after did id, error's gone.

i'm deploying app in these way: - export war eclispe - deploy trough tomcat web manager

i tried: - change server tomee - place jar libs in web-inf/lib

structure of application folder after deploying tomcat:

index.jsp makes http request servlet storeserver

any ideas how make run properly?

i have found solution. error caused different java versions on vps(oracle 1.7) , computer(openjdk 1.7). have made .war on vps , works fine.
