Hi,

This article is about a *Servlet call to injected EJB3 Session Bean*. 
Note that JNDI calls are not required.
The application in attachment will work fine with JBoss-5.1.0.GA_JDK6/ JDK1.6.0_21.

The application can be reached at  http://<IPAddress>:8080/servletejb3 http://<IPAddress>:8080/servletejb3
welcome file is a jsp file, which submits a form with user input to the servlet.
The Servlet calls the session bean which returns a value in uppercase 
which is reloaded into the textbox in the same JSP.

Extract the attachment and run ant deploy after modifying the script 
to point to your environment's jboss home.

Fire up the JBoss and pull up the app.

Thanks
