Java EE (Java Enterprise Edition) General Discussion

Hi,

I wrote a simple Entity Bean class. I am using JBuilder5, Weblogic 6.0 sp2 and Oracle 8.1.7.
In JBuilder under Tools->Enterprise Setup->Database Drivers, I have added the Oracle driver.

I created a project and created all interfaces and classes. JBuilder generated a class that extends the Bean class, in which the code to accecc datase are implemented.

This is the code it generated for setEntityContext method.

public void setEntityContext(EntityContext entityContext) throws RemoteException {
super.setEntityContext(entityContext);
try {
javax.naming.Context context = new javax.naming.InitialContext();
try {
dataSource = (DataSource) context.lookup("java:comp/env/jdbc/DataSource");
}
catch(Exception e) {
throw new EJBException("Error looking up dataSource: " + e.toString());
}
}
catch(Exception e) {
throw new EJBException("Error initializing context in setEntityContext of BMP:" + e.toString());
}
}

I am able to compile, deploy the beans. After creating a client application, if I run the client, I am getting the following exception.

java.rmi.RemoteException: EJB Exception: ; nested exception is:
javax.ejb.EJBException: Error initializing context in setEntityContext of BMP:javax.ejb.EJBException: Error looking up dataSource: javax.naming.NameNotFoundException: Unable to resolve jdbc/DataSource Resolved: '' Unresolved:'jdbc' ; remaining name 'DataSource'

javax.ejb.EJBException: Error initializing context in setEntityContext of BMP:javax.ejb.EJBException: Error looking up dataSource: javax.naming.NameNotFoundException: Unable to resolve jdbc/DataSource Resolved: '' Unresolved:'jdbc' ; remaining name 'DataSource'

<<no stack trace available>>

The JNDI name for the data source is correct. I checked that. I don't find any mistake.
Can anybody find a mistake and help me solve this error.

Thanks in advance.
