    Problem using DB2 7.1 and 8.1 drivers together

    Michael Aplin Newbie

      Windows XP/JBoss 3.2.7/JDK1.4

      I am attempting to create two connection pools in JBoss, one that uses the DB2 7.1 Type 2 driver and one that uses the DB2 8.1 Type 4 driver. The problem is that the 7.1 pool does not work unless it is created before the 8.1 pool. If the 8.1 pool is created first, JBoss uses the 8.1 driver class to create the 7.1 connections. Here is the configuration info and log output. Any help is greatly appreciated!

      DB271-ds.xml
      <jndi-name>DB2v71</jndi-name>
      <connection-url>jdbc:db2:dbd2</connection-url>
      <driver-class>COM.ibm.db2.jdbc.app.DB2Driver</driver-class>

      DB281-ds.xml
      <jndi-name>DB2v81</jndi-name>
      <connection-url>jdbc:db2://mvsdev2.test.com:4240/test_dbd2</connection-url>
      <driver-class>com.ibm.db2.jcc.DB2Driver</driver-class>
