    Help for setting up PostgreSQL JDBC pool

    Shane Ye Newbie

      I am using JBOSS 2.4.5 and try to set up JBDC pool for Postgresql.
      my PostgreSQL version is 7.2.1
      I tried both jdbc7.0-1.2.jar and pgjdbc2.jar as driver

      code i put in jboss.jcml are:


      org.postgresql.Driver



      shaneTestDS
      org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl


      jdbc:postgresql://192.168.255.198:5432/shane_test

      1200000
      postgres
      10

      false
      false
      false
      true
      120000
      1800000
      false
      false
      1.0
      0




      relevant code I put in standardjaws.xml are

      java:/shaneTestDS
      <type-mapping>PostgreSQL</type-mapping>
      false

      for some reason when I startup Jboss, it shows error like this:

      //**************Jboss server output********************

          I am by no stretch of the imagination an expert in this field, yet a few questions:

          1) You did copy the pgjdbc2.jar into jboss' lib/ or lib/ext directory, didn't you?

          2) I am not sure whether those drivers you mentioned do indeed support XA data sources, that is distributed transactions. The PostgreSQL JDBC Status Page under http://lab.applinet.nl/postgresql-jdbc/ isn't shure either. What's more, I strongly suspect that this is not what you want. Most often, you will only need local transactions. So you should configure a local data source loader. Unfortunately, I'm using JBoss 3.0 and thus unable to offer you precise instructions as to how to do so.

          Anyway, hope this helps.

          Good luck,

          Olaf

            Thank you for clue

            Yes I did copy the drivers into the right place lib/ext

            I have no idea about the distributed transaction, but the example i found works for other database, i just changed the driver to use PostgreSQL driver and the URL of the database, and many tutorials I read said this too. My database does locate on another machine.
            just dont know why its not working for me
