Hello, I have a problem with implementation WebApplication with JPA.

Servlet is in the attachment...

Exception is:

java.lang.RuntimeException: javax.naming.NameNotFoundException: Name persistence is not bound in this Context
web.EplDetails.findByID(EplDetails.java:126)
web.EplDetails.processRequest(EplDetails.java:58)
web.EplDetails.doGet(EplDetails.java:84)
javax.servlet.http.HttpServlet.service(HttpServlet .java:627)
javax.servlet.http.HttpServlet.service(HttpServlet .java:729)

Can anybody help me with it???

I don't use approach with JNDI and Context
but if you use Eclipse i can post a simple manual
how to create entities from tables,
get persistence.xml file with tag:
<persistence-unit name="JPA1">

and then just simply call it from your code:

....
EntityManagerFactory emf = Persistence.createEntityManagerFactor("JPA1");

EntityManager em = emf.createEntityManager();
...
