In Calling EJB 3 from JRuby client, I wrote how to call EJB3 deployed to glassfish from a JRuby script. This post will show how to do it with JBoss EJB3, reusing the same EJB3 as the previous post (A simple EJB 3 on JBoss application server). Steps 1-7 (creating EJB3 classes, starting JBoss server, deploying EJB, preparing jndi.properties and log4j.properties) are exactly the same as that post. Here I will show the client script code and how to run it.

The JRuby script (testEJB.rb) is almost identical to the one for glassfish, except the default jndi name. TODO: pass it in as parameter instead of hardcoding it.

require 'java'
include_class 'javax.naming.InitialContext'

ic = InitialContext.new
foo = ic.lookup("FooBean/remote")
result = foo.echo("This is foo!")
puts "Calling the EJB 3 : #{foo} returned #{result}"

Before running the script, we need to set the environment variable CLASSPATH, which is of course different from the one for glassfish.

set CLASSPATH=%JBOSS_HOME%\lib\*;%JBOSS_HOME%\client\*;%JBOSS_HOME%\server\default\lib\*;C:\simple-ejb3\classes
jruby testEJB.rb

The above classpath value works only with JDK 6 or later. If you are stuck with JDK 5, then:

set CLASSPATH=%JBOSS_HOME%\lib\jboss-aop-jdk50.jar;
%JBOSS_HOME%\client\jbossall-client.jar;
%JBOSS_HOME%\server\default\lib\jbosssx.jar;
C:\simple-ejb3\classes
