STEP 1:
1. Chose File > New Project from the main menu.
2. Selected Enterprise Application from the Enterprise category and clicked Next.
3. Named the project Chapter2 and set the project location.
4. Set the server to GlassFish and set the Java EE Version to Java EE 5.
6. Selected the options 'Create EJB Module' and 'Create Application client model'
7. Clicked on Finish.

STEP 2: Created Session Bean

Expanded the Chapter2-ejb module and in the source packages created two java files as follows:
HelloUser.java





and HelloUserBean.java





STEP3: Created client code:

Expanded the Chapter2-app-client module and in the source packages created two java files like below:

Main.java





and HelloUserClient.java





other than above mentioned i did not touch anything in the Netbeans6.0 IDE.I did not touch any XML file also.

I just clicked on the run project and i am getting this error:
