This may be unfair, so I will ask my question in two parts.
First; I am trying to use the JavaWebServer v2.0 (trial version) to
compile a JSP and
communicate with jBoss to process an Enterprise JavaBean (EJB) deployed
there.
The code is:
<% try { %>
<% System .setProperty ("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory") ; %>
<% System .setProperty ("java.naming.provider.url", "localhost:1099")
; %>
<% javax.naming.InitialContext ctx = new javax.naming.InitialContext
() ; %>
<% Object obj = ctx .lookup ("examples/HelloWorld") ; %>
<% HelloWorld_ejbHome hello = (HelloWorld_ejbHome)
javax.rmi.PortableRemoteObject .narrow (obj, HelloWorld_ejbHome .class) ;
%>
<% } catch ( javax.naming.NamingException exception ) { %>
<% exception .printStackTrace () ; %>
<% } %>
I have tested the EJB using a simple Java client program, and similar
could works there.
Through various combination of including and excluding various, the code
above fails
at the 'ctx .lookup ("examples/HelloWorld")' with the following exception
trace returned
by the JSP servlet to my browser. (The exception is not caught by my code,
therefore it
is not a 'javax.naming.NamingException'.)

My unfair question . Is this a JavaWebServer security conflict that can
be configured to
allow a JSP in the server to communicate with a EJB deployed jBoss ? Or
am I missing
something ?
Second, it seems that all the EJB servers that I have looked at have the
web server and
EJB server running in the same Java Virtual Machine. I am trying to setup
a true n-tier
application where the web server and EJB server are on separate platforms.
The EJB server
must run on a legacy platform to server data from the system. Is it
possible to configure
a web server (perhaps Apache w/tomcat) on one platform to communicate with
jBoss on another
platform ? And disable the web server functions built into jBoss ?
