Hi there,

I'm having problems looking up my datasource.

In config.xml :

My bean is a stateless session bean.
I try to obtain a connection as follows :

initCtx = new InitialContext();
DataSource ds = (javax.sql.DataSource)
initCtx.lookup("wombat-ds-dynsql");

I get the following exception :

javax.naming.NameNotFoundException: Unable to resolve
wombat-ds-dynsql. Resolved: '' Unresolved:'wombat-ds-dynsql' ;
remaining name ''

I have tried using "java:/comp/env/jdbc/wombat-ds-dynsql" for lookup,
but that doesn't work either.

Please help!!!

You should look for the name of the datasource not the JNDI_NAME. try doing
this

initCtx = new InitialContext();
DataSource ds = (javax.sql.DataSource)

initCtx.lookup("Dynsql DataSource");

it should work...

Hi Isabelle,

There are several sources of your problem.

o You don't provide correct JNDI name. Provide
correct name.

o You have not set up targer for the DataSource.
Provide correct target.

o You DataSource has not started up because
connection pool it's based is not started. Check
log and make sure connection pool and ds started.

Regards,
