    unable to connect to db

    David Clark Newbie

      I am unable to get my app to connect to a running instance of mySQL. I can connect to it via Eclipse IDE using a URL:

      jdbc:mysql://localhost:3306/mydb

      But in my mysql-ds.xml file I have this:


      <local-tx-datasource>
      <jndi-name>MySqlDS</jndi-name>
      <connection-url>jdbc:mysql://127.0.0.1:3306/mydb</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>user</user-name>
      <pass word>none</pass word> <-- formatted to show in this post
      </local-tx-datasource>


      But when I try to access the site I get this:

      Caused by: org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (java.sql.SQLException: Cannot connect to MySQL server on 127.0.0.1:3306. Is there a MySQL server running on the machine/port you are trying to connect to? (java.lang.NumberFormatException))

      Does anyone know what might prevent JBOss 4.0.2 from connecting to the db?
