When I am trying to deploy my ear file. I am getting the error mentioned below. I have made
a connection pool and 3 data sources at console. Is there a problem with the way I have
defined them. Please do let me know.
Thank You
Ronak Parekh

Name : oraclePool
URL : jdbc:weblogic:builder
Driver classname : weblogic.jdbc.oci.Driver
Properties(key=values): servername=ronakserver

Name : Gangster
JNDI Name: Gangster
Pool Name: oraclePool
Name : Organization
JNDI Name: Organization
Pool Name: oraclePool
Name : Job
JNDI Name: Job

You have a couple problems.
First, the jndi-name in the reference-descriptor of your weblogic-ejb-jar.xml file should refer to the Datasource NOT the Connection Pool.
Secondly, you are giving your datasource and ejbs the same JNDI name. This is a big no-no. I like to adopt a similar convention to package structures for JNDI names. So the datasource would com.organization.datasource.name and the ejbs would be com.organization.ejb.name.
Make sense?

I am still getting the same error:
Unable to deploy EJB: OrganizationEJB from sempire_bc.jar
The DataSource with the JNDI name: OrganizationDB can not be located. Please ensure that the DataSource has been deployed
successfully and that the JNDI name in your EJB Deployment descriptor is correct.
In my console, I have created a connection pool 'oraclePool' and 3 datasource 'jdbc.GangsterDB', 'jdbc.OrganizationDB' and
'jdbc.JobDB'. I have also specified the target server and there seems to be no error. I have checked 'Monitor All Connection
Pools' and oraclePool is running. I still do not understand the problem that I am getting and have no clue how to solve it.
Thank you

You are messing up with lines like these:

You are setting the jndi name of your ejb to the jndi name of your datasource. Bad news abounds.

Following is the code that works for me.See if it useful to you .
try {
Context ctx = null;
ctx = new InitialContext();
javax.sql.DataSource ds
= (javax.sql.DataSource) ctx.lookup("put here jndi name of the datsource that you created in console");
conn = ds.getConnection();
logger.debug("Making connection...\n");

stmt = conn.createStatement();
Since i am not using cmp i don't have the descriptor files.
Thanks,
smita
