    Problem configuring datasource in JBoss AS 7

    Marcos Antonio Novice

      Hello, everybody!

       

      I'm having problems trying to configure a datasource in JBoss AS 7. I did this:

       

      1. Copied the JDBC driver file (postgresql-9.0-801.jdbc4.jar) to "JBOSS_HOME/standalone/deployments" directory.
      2. Added the following datasource element to the "JBOSS_HOME/standalone/configuration/standalone.xml" file:


      <datasource jndi-name="java:jboss/datasources/SCDH_DS" pool-name="SCDH_DS" enabled="true" jta="true" use-java-context="true" use-ccm="true">
          <connection-url>
              jdbc:postgresql://localhost/solicitacoes
          </connection-url>
          <driver>
              org.postgresql.Driver
          </driver>
          <new-connection-sql>
              select 1
          </new-connection-sql>
          <security>
              <user-name>
                  user
              </user-name>
              <password>
                  password
              </password>
          </security>
          <validation>
              <check-valid-connection-sql>
                  select 1
              </check-valid-connection-sql>
              <validate-on-match>
                  false
              </validate-on-match>
              <background-validation>
                  false
              </background-validation>
              <useFastFail>
                  false
              </useFastFail>
          </validation>
      </datasource>

       

      Now, when I start the server I get these messages:

       

      08:01:43,390 INFO  [org.jboss.as.controller] (Controller Boot Thread) Service status report
         New missing/unsatisfied dependencies:
            service jboss.jdbc-driver.org_postgresql_Driver (missing)

      I would like to know what I am missing or doing wrong.

       

      Thank you.

          I run into the same problem with mysql driver. Somehow the jar from deplayments directory gets deployed late or lazy, so I decided to create a module instead. That worked quite well and the error on startup was gone.

          Have a look here how to do it: http://community.jboss.org/wiki/DataSourceConfigurationInAS7#Installing_a_JDBC_driver_as_a_module

          or http://www.mastertheboss.com/jboss-application-server/308-jboss-as-7-introduction.html (Section: "Step #2: Install the driver")

           

          hope that helps

            Hello, Christoph! Thank you for the answer.

             

            I'm almost sure that if I create a module, as you did, the problem will be solved. I just would like to make this work in the simplest way possible, I mean, by installing the JDBC driver as a deployment, not as a module, as the article pointed by you (which I already read) says it's possible. But unfortunatelly it seems that installing the JDBC driver as a deployment doesn't work as it should. Maybe I'll be forced to install it as a module.

              The problem is the <driver> tag. It have to point to driver name, that is in case of hot deployment the filename of deployed jar.

              For a complete description have a look here: http://www.javalinux.it/wordpress/2011/07/14/how-to-create-an-manage-datasources-in-as7/

                hi Stefano,

                hmm, good point. I also used some other driver name ("mysql-connector"), as I did not like the version number in the name. Maybe that's why it throw that error for me, too.

                  Hello, Stefano.

                   

                  If I understand what you said, I changed the driver tag to this:

                   

                  <driver>

                      postgresql-9.0-801.jdbc4.jar

                  </driver>

                   

                  But I'm still getting the missing/unsatisfied dependencies message, although it says that the service was corrected:

                   

                  08:51:50,937 INFO [org.jboss.as.controller] (Controller Boot Thread) Service status report

                    Hi Marcus,

                     

                    log is saying that dependency has been corrected after jar deployment. It's correct and after last message your DS should work fine.

                     

                    Look at this log and my explanations:

                     

                    08:51:50,937 INFO [org.jboss.as.controller] (Controller Boot Thread) Service status report

                    New missing/unsatisfied dependencies:

                    service jboss.jdbc-driver.postgresql-9_0-801_jdbc4_jar (missing)

                     

                    I saying that jdbc driver isn't availabel during server startup and so the DS has a missing dependency. Then....

                    08:51:50,953 INFO [org.jboss.as.server.deployment] (MSC service thread 1-3) Starting deployment of "postgresql-9.0-801.jdbc4.jar"

                    08:51:51,062 INFO [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-3) Deploying non-JDBC-compliant driver class org.postgresql.Driver (version 9.0)

                    Here you have deployed the jar, or if the jar was already in place, server has reached the deploy phase for the jar.

                     

                    08:51:51,062 INFO [org.jboss.as.connector.subsystems.datasources] (MSC service thread 1-3) Bound data source [java:jboss/datasources/SCDH_DS]

                    Dependency are so fixed, and the DS can be bound

                    08:51:51,093 INFO [org.jboss.as.server.controller] (DeploymentScanner-threads - 2) Deployed "postgresql-9.0-801.jdbc4.jar"

                    08:51:51,093 INFO [org.jboss.as.controller] (DeploymentScanner-threads - 2) Service status report

                    Newly corrected services:

                    service jboss.jdbc-driver.postgresql-9_0-801_jdbc4_jar (now available)

                    And the controlle tell you explicitly that the service previosly missing is now available.

                     

                     

                    hoping it helps

                      Yes, I saw the message saying that the service jboss.jdbc-driver.postgresql-9_0-801_jdbc4_jar is now available. I just got confused because I also saw the message "Newly corrected services". Well, if something was "corrected", I thought I was still doing something wrong or missing something for JBoss to have the need to correct something. But if JBoss display these messages for all JDBC drivers installed as a deployment ("missing" first and after that, "now available"), I think that there's no problem. Thank you, Stefano.
