Hi, I have created an own datasource called test-ds.xml. First time, it had a local-tx-datasource with next parameters: - jndi-name : testDS - connection-url : jdbc:mysql://10.90.31.14:3306/test It works ok. But now, I have created a new mySQL instance with the name 'testB'. I have changed the datasource and now it has this parameters: - jndi-name : testDS - connection-url : jdbc:mysql://10.90.31.14:3306/testB After Jboss has started, when I run my web-app it uses the old database (test) but on the datasource file, the connection-url's name is testB. Any ideas? Thanks. Manuel. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4200562#...
