JNDI look up problem in sun java app server 8.1

Hello everyone,

I am new to JNDI and application servers. I have a
sample web application that accesses
data stored in postgresql that I want to deploy on the
sun java application server 8.1.
I believe I have followed the guidelines in sun java
i.e register jdbc driver, create connection pool,
jdbc resource. I have done this and i verified this by
clicking the ping button and a success message
was displayed. I am not sure but i think the problem
is with my code:

InitialContext ic = new InitialContext();

 DataSource source =
(DataSource)ic.lookup("java:comp/env/jdbc/books");

         connection = source.getConnection();


  each time i run the application i get the following
exception

javax.naming.NameNotFoundException: No object bound to
name java:comp/env/jdbc/books

        at
com.sun.enterprise.naming.NamingManagerImpl.lookup(NamingManagerImpl.java:751)
        at
com.sun.enterprise.naming.java.javaURLContext.lookup(javaURLContext.java:156)
        at
com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:307)
        at
javax.naming.InitialContext.lookup(InitialContext.java:392)
        at
com.deitel.advjhtp1.store.TitlesBean.<init>(TitlesBean.java:38)

The name of the data source i configured in sun java
is jdbc/books. I made sure that the database exists
and can be accessed from a java application. I
confirmed this by using the Drivermanager class.

My question is where have I gone wrong? is it my code
or am I missing something out in the
configuration settings i made in sun java? some of the
settings I made in sun java are as follows:

datasource classname:
org.postgresql.ds.PGSimpleDataSource

resource type: javax.sql.connectionPoolDataSource

Additional properties:

datasourceName: jdbc/books
user: postgres
port:5432
databaseName: books
serverName: localhost


Thanks in advance.
Roman

Roman,

Did you try following,

ic.lookup("jdbc/books");
