MaheshKannan: Mahesh's Weblog about EJB 3.1

The GlassFish Enterprise Server V3 Prelude has been released. In this blog, I will describe the steps to install the EJB container to have a sneak preview of some of the EJB 3.1 features.

First download the V3 prelude bundle

Then start the server by doing: java -jar <install_dir>/glassfish/modules/glassfish.jar

Open a browser window and access the V3 administration GUI by accessing the url: http://localhost:4848

From the left panel, select the uptate tool

Select glassfish-ejb component and click install to install the ejb-container module.

Restart the server and you are now ready to deploy ejb applications to the V3 prelude application server

Note:

Only Stateless Session beans and Singleton beans with local interfaces, no interface view are supported. Stateful, Message driven and EJB 2.x entity beans are not supported. Remote interfaces and Remote business interfaces for any of the bean type are not supported yet. Timer Service is supported. See Marina's blog about timer service.

EJB container implementation in V3 Prelude gives you an early look at some of the EJB 3.1 features. It is not a full, feature-complete container implementation and is not suitable for production deployments. It is suitable for experimentation and exploration. Experiment, take a look at the new approach being taken in GlassFish v3, and then let us know what you think
