    jdbcOdbcBridge service for CMP (JBoss3)

    David Treves Newbie

      Hi all,

      I searched ALL the forums, and could not find this question... I am using JBoss 3 (beta) and I wish to create a service that will connect me to an MS SQL server 7 database.

      I managed to get to some examples of "*-service.xml" files, but none were for jdbcOdbcBrigde. I am aware of the performance of the bridge, but that's another issue...

      Can anyone please post a valid version of an XML service file for connecting via ODBC to a DB server using that bridge?

          Don't use that lame odbc bridge driver. There are other drivers available, and there is even one available from ms at:

            Hi Dain,

            I am working with SQL 7, and currently there is no available FREE JDBC driver for it.

            If there is a driver please notify me...

              I'm struggling with this same issue. I used to connect with the jdbc/odbc bridge from JBoss 2.4 to SQL Server 7.0 with no issues. But with the upgrade to JBoss 3.0, I'm connectionless.

              I'm on NT4-SP5, Java SDK 1.4, JBoss 3.0, and my config files look like this:

              === login-config.xml ===
              <application-policy name = "MSSQLDbRealm">

              <login-module code = "org.jboss.resource.security.ConfiguredIdentityLoginModule"
              flag = "required">
              <module-option name = "principal">sa</module-option>
              <module-option name = "userName">sa</module-option>
              <module-option name = "password">scoobydoo</module-option>
              <module-option name = "managedConnectionFactoryName">jboss.jca:service=LocalTxCM,name=MSSQLDS</module-option>

              === login-config.xml ===

              === mssql-service.xml ===

              <!--make the rar deploy! hack till better deployment-->

              === mssql-service.xml ===

              The error I get is here:
              [java] org.jboss.util.NestedSQLException: Failed to register driver for: or
              g.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl; - nested throwable: (java.lang.Cl
              assNotFoundException: org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl); - nested
              throwable: (org.jboss.resource.ResourceException: Failed to register driver for

              g.ClassNotFoundException: org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl))

              So I'm thinking that the XADataSourceImpl is in a different place or doesn't exist at all anymore in 3.0. I can't download the JBoss source here at work because of a network security policy that I won't get into. I'll do that at home when I get a chance... Using Google here at work, I didn't find much.

              The other thing I wonder is if I should be using XADataSourceImpl anyway since in the config files I specified LocalTxCM rather than xa, but maybe I'm out to lunch on that.

              Well, any help is appreciated. I just found the free driver at thinweb.com so I'll try that too.

                replying to myself...

                The thinweb.com driver worked for me on the first try. I haven't done lots of testing or anything, but I read the contents of a table so that's a good start.

                Here's how you do it:
                1) copy the TwFreeTds_1.0.jar to your lib directory
                2) use the configuration of my previous post except for the following two lines in mssql-service:

                <config-property name="ConnectionURL" type="java.lang.String">jdbc:twtds:sqlserver://machinename/databasename</config-property>
                <config-property name="DriverClass" type="java.lang.String">com.thinweb.tds.Driver</config-property>

                3) enjoy the connected goodness

                good luck everyone,
