EJB questions are best answered on ejb  mailing list. To answer your question: Check your config.xml file and see the JDBCDataSource tag, and JDBCConnectionPool tag.   see if there names are matching the ones as you specified in the ejb-jar.xml and weblogic-ejb-jar.xml.   -----Original Message----- From: kongtao [mailto:[EMAIL PROTECTED]] Sent: Sunday, August 25, 2002 6:04 PM To: [EMAIL PROTECTED] Subject: I can't get the resource reference through <resource-ref> element!
