JSP calls EJB in jboss

[Imposter]

If I call EJB from client with JavaApp( not JSP) I must have some
interface e.g: HomeInterface , a Interface which extends EJBObject.
And I run my program successful.
But JSP Page which call EJB is on server(run JBOSS with Jetty).
Where do I put class interface in JBOSS for my JSP Page use it?
Thank you very much!

You can put it where you put all your other classes. Typically:
1 - in WEB-INF/classes
2 - in a jar in WEB-INF/lib

I zip my web-folder into file with extension war(class file I copied into folder classes of WEB-INF).Then I copy this file
into folder server/default/deploy in JBoss(Jetty integrated)But Error message appear when I run my jsp page as follow:

Two dumb things to check:
1 - did you import the classes "<%@ page import="com.whatever.User" %>
2 - Did you put the jar file with them in the WEB-INF/lib directory? Does the jar file really contain the classes you need? Manually verify this.

If you just can't get it to load, go to the JMX console and look for
the jboss.web section. Inside of there, look for an MBean for your context. It will look something like this:
JBossWebApplicationContext=3,Jetty=0,context=/yourApp
Click on the MBean and look at the "classPath" attribute. What do you see? Is your class in a jar in the classpath for the webapp?
