Hi,
What is the difference between what you have done
and what it is done in the example eb?
Have a look at the $JONAS_ROOT/examples/src/eb
you will see that in AccountExplBean.java the getConnection method
is written as:
private Connection getConnection() throws EJBException, SQLException {
if (dataSource == null) {
// Finds DataSource from JNDI
Context initialContext = null;
try {
initialContext = new InitialContext();
dataSource =
(DataSource)initialContext.lookup("java:comp/env/jdbc/AccountExplDs");
} catch (Exception e) {
System.out.println("Cannot lookup dataSource"+e);
throw new javax.ejb.EJBException("Cannot lookup dataSource ");
}
}
return dataSource.getConnection();
}
with in the ejb-jar.xml :
<resource-ref>
<res-ref-name>jdbc/AccountExplDs</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
and it's running very well!
have you suceed to run eb example in youe environment?
