how to get the MySQL database jndi connection in weblogic using Ecllipse

Answer 1

Well weblogic and tomcat wont differ in the way you get a connection from the pool.. but at first you need to initialize a database pool in the weblogic server by going to the Administration Console:

under your server name to the left select Services Then go to Data Sources and add a New Data source..

Please note that if you're in production mode in weblogic then you must click on lock and edit in the upper left corner and when done you should click on release configuration in the same location.. but when under development you wont need to do that..

After adding a new MySQL data source just go to java and

Context initialContext = new InitialContext();
DataSource ds = (DataSource) initialContext.lookup("THE_MYSQL_JNDI_NAME_YOU_CHOSE");
Connection conn = ds.getConnection();

And that's it.. :-)
