Hi:
I have been trying to implement a simple JSP to EJB communication test from
an EAR file deployed on JBoss/Tomcat but I have been unsuccessful.
This is the EAR file breakdown:
TestEAR.ear
----application.xml
----TestWAR.war
--------WEB-INF
------------lib
----------------ClientJAR.jar
--------------------com
------------------------munoz
----------------------------ejb
--------------------------------Person.class
--------------------------------PersonBean.class
--------------------------------PersonHome.class
------------web.xml
--------ejbTest.jsp
----TestJAR.jar
--------META-INF
------------ejb-jar.xml
--------com
------------munoz
----------------ejb
--------------------Person.class
--------------------PersonBean.class
--------------------PersonHome.class
In the JSP I am making the following call:
Context initialContext = new InitialContext();
Object personHome = null;
try
{
personHome = initialContext.lookup("PersonBean");
if (personHome == null)
{
out.println("PersonHome is null");
}
else
{
out.println("Success!");
}
}
catch (Exception exception)
{
System.out.println(exception);
out.println(exception);
exception.printStackTrace(System.out);
}
The page compiles correctly, but when I call it, I get back the following
exception:
[EmbeddedTomcat] javax.naming.CommunicationException [Root exception is
java.lang.ClassNotFoundException: com.munoz.concept.person.PersonHome]
javax.naming.CommunicationException. Root exception is [EmbeddedTomcat]

My confusion comes from the fact that the JSP compiles even though I am
importing com.munoz.ejb.PersonHome, meaning that the class can be found at
compile time, but the class cannot be found on runtime. Any ideas?
Thanks in advance,
Felix Munoz
