Read this page for installing and setting up the environment for developing and deploying EJB 3. For simplicity, the session bean and the client to access the session bean are created in the same project.
The business interface will be created in different package com. Interface can be either Remote or Local. In this example we have used Remote. Bean type can either be Stateful or Stateless. In this example we have used Stateless. The next step is to deploy the bean on the server.
If the project is deployed properly with global JNDI mapping then you will see the following message in the console. Creating Client The next step is to write a remote Java client application with main for accessing and invoking the EJBs deployed on the server Client uses JNDI to lookup for a proxy of your bean and invokes method on that proxy.
Therefore, the starting point of interacting with the naming service is to obtain a Context by providing the properties specific to the server implementation being used.
In our case it is, JBoss Application Server. To create a javax. InitialContext, we need to initialize it with properties from the environment. Otherwise the code written in this class should be repeated in all clients. It should be URL string.
Call business logic System. The above error is due to the long classpath of the client. Client requires only few jar files to run the application. Since we have created client in the same project as the session bean, client classpath has all the jar files from JBoss AS. We have to remove some of the jar files to shorten the classpath, i.Servlet program is not like, writing java code and execute through command prompt.
We need to follow the following steps in order to develop any servlets program.
Even for a simple HelloWorld program also one must follow this standard directory structure which is prescribed by sun. In this tutorial you will create a simple EJB component and a client web application.
This tutorial will introduce you to Session beans and the Web Tools Platform project's support for XDoclet and server tools. In order to run the EJB and Web modules from Eclipse (which will allow you to test and. Hibernate configuration file. First of all, you need to tell Hibernate some information regarding the database system you intend to use, such as host name, port number, JDBC driver class name, database connection URL via some kind of configuration.
