    Help: JBoss 2.4.4 and MySQL

    Pyung Yoon Newbie

      I am new to JBoss and trying to get JBoss 2.4.2 and MySql working together. Following is what I did:

      1) modify jboss.jcml


      org.gjt.mm.mysql.Driver



      org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl
      mySQLDS
      jdbc:mysql://localhost/BFG
      1200000
      bfguser



      2) modify standardjaws.xml

      java:/mySQLDS
      <type-mapping>mySQL</type-mapping>
      false

      When I run JBoss, I got the following msgs:

      [INFO,JdbcProvider] Starting
      [INFO,JdbcProvider] Started
      [INFO,mySQLDS] Starting
      [INFO,mySQLDS] XA Connection pool mySQLDS bound to java:/mySQLDS
      [ERROR,mySQLDS] Stopped
      java.lang.NullPointerException

      Does anyone know what the problem is? I would appreciate your help.
