Hi Romain, If I understand you correctly, you are saying that id and resource name do not match
Here :- <Resource id="<b>jdbc/localDB*" type="javax.sql.DataSource"> JdbcDriver com.mysql.jdbc.Driver JdbcUrl jdbc:mysql://localhost:3306/localdb MaxActive 100 MaxIdle 30 MaxWait 10000 and <resource-ref> <description>MySQL Connection</description> <res-ref-name>*jdbc/localDB*</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> isn't resourcename = jdbc/localDB same as id="jdbc/localDB" What exactly is the prefix that you are mentioning to be added in resources.xml? -- View this message in context: http://openejb.979440.n4.nabble.com/MySQL-resource-in-Tomee-1-5-2-tp4665872p4665891.html Sent from the OpenEJB User mailing list archive at Nabble.com.
