This is an example of a JSP-page calling a Session Bean. The result looks like this:
I have tried to strip of everything just to make this example as easy as possible to understand. This is an example using Geronimo 2.0, Java 1.5 and EJB 3.0.

package org.apache.geronimo.samples.mytimepak;
import javax.ejb.Stateless;
@Stateless
public class MyTimeBean implements MyTimeLocal {
public String getTime() {
String s = new java.util.Date().toString();
return s;
}
}

MyTimeLocal.java is the Local interface. As this EJB will only be used from a JSP-page that is running in the same server (same JVM) I use a Local interface that do not make use of the network.

You can checkout the source code of this sample from SVN:
svn checkout http://svn.apache.org/repos/asf/geronimo/samples/trunk/samples/mytime
Building
Use a command prompt to navigate into the mytime directory and just give mvn clean install site command to build. It will create the mytime-ear-2.0-SNAPSHOT.ear under the mytime folder. Now, you are ready to deploy mytime application in the Geronimo Application server.
...
To test the sample web application open a browser and type http://localhost:8080/mytime.
