Whats is JDBC DataSource Factory ??

Question

What is the biggest different between from JDBC DataSource and JDBC DataSource
Factory ??
It says that JDBC DataSource Factory enables the EJB to map a resource factory
reference in the EJB deployment descriptor. But can't I do the same thing to JDBC
DataSource ????

Answer 1

Did you target your datasource when you created it?
Did you look at the server output log to if that the connection pool and
data source had any errors in deploying to the target?

I defined a datasource for sybase named let us say "SDS".
I get error with my test program as follows.
javax.naming.NameNotFoundException: Unable to resolve 'SDS'. Resolved '';
remaining name 'SDS'
How do I troubleshoot this error?
Is there a way to list names of JNDI datasources for a WLS instance?
I am sure I created jdbc datasource "SDS" under base_domain via console
and tested the connection
My current test program code is as follows.
Properties prop = new Properties();
prop.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
prop.put(Context.PROVIDER_URL,
"t3://localhost:7001");
System.out.println("DEBUG: create initialConext:start");
InitialContext ic = new InitialContext(prop);
System.out.println("DEBUG: create initialConext:end");
DataSource ds =null;
System.out.println("DEBUG: looking up datasource:start");
ds = (DataSource)ic.lookup("SDS");
System.out.println("DEBUG: looking up datasource:end");
System.out.println("DEBUG: get Connection:start");
Connection c = ds.getConnection();
System.out.println("DEBUG: get Connection:end");
}catch( Exception ex){
System.out.println(ex.toString());
Thanks
