Just so that I am understanding this correctly, would it be possible for you to provide a resources.xml sample, the web.xml snippet and a small code for datasource from initialcontext lookup - ??
Mine are here :- Resources.xml ( in WEB-INF folder of deployed war) <Resource id="jdbc/localDB" type="javax.sql.DataSource"> JdbcDriver com.mysql.jdbc.Driver JdbcUrl jdbc:mysql://localhost:3306/localdatabase MaxActive 100 MaxIdle 30 MaxWait 10000 UserName username Password password </Resource> web.xml ( in WEB-INF folder of deployed war) <resource-ref> <description>MySQL Connection</description> <res-ref-name>jdbc/locallDB</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> Code to lookup and use datasource InitialContext ic = new InitialContext(); Context envCtx = (Context) ic.lookup("java:comp/env"); DataSource ds = (DataSource)envCtx.lookup("jdbc/localDB"); -- View this message in context: http://openejb.979440.n4.nabble.com/MySQL-resource-in-Tomee-1-5-2-tp4665872p4665892.html Sent from the OpenEJB User mailing list archive at Nabble.com.
