When I start the JRun4 server, the \JRun4\logs\default-event.log contained:
error Deployer Service failed to deploy file:/C:/JRun4/servers/default/default-ear/
* EJB Container Factory could not deploy EJB container from file:/C:/JRun4/servers/default/default-ear/default-ejb/.
* The class specified, com.zbeans.Entity1Bean, by ejb-class was not found in the EJB jar.
ejb-jar.xml resides under
C:/JRun4/servers/default/default-ear/default-ejb/Meta-inf
Entity1Bean.class resides under
c:\JRun4\servers\default\default-ear\default-war\WEB-INF\classes\com\zbeans.
I made sure Entity1Bean.class existed in Entity1.jar. I even tried using
absolute, instead of relative paths, when creating the jar file.
I tried placing Entity1.jar in various folders, such as
C:/JRun4/servers/default/default-ear/default-ejb/Meta-inf,
...\default-war\WEB-INF\classes\Meta-inf\.
I also renamed Entity1.jar to ejb.jar, but this also was not solution.
The various online documentation, and hardcopy books suggest different
paths (relative to the classes folder) to create the Meta-inf folder.
Does it have to appear under a specific parent folder for each type of
server (Weblogic vs Websphere vs Jrun)? I am using the JRun 'default'
server, which has worked for my simple beans in JSP.
I'm still unclear where the Entity1.jar, ejb-jar.xml should reside, and
whether it is mandatory to name the jar "ejb.jar" (I don't think so)?
My ejb-jar.xml contains:
<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">

I successfully referenced a simple bean in JSP residing under
C:\JRun4\servers\default\default-ear\default-war\web-
inf\classes\com\zbeans\JavaBean_eg1.class. This would suggest the server
is running properly. I used the following Bean class reference in JSP:
<jsp:useBean id="prJavaBean1" scope="page" class="com.zbeans.JavaBean_eg1" />
