    learner Newbie

      Hi All
      Is there any step-by-step resource available for sql server 2000 and Jboss 3.2 connectivity?
      If not, then how i can configure sql server 2000 with jboss 3.2.

              Where did you put the msbase and msutil jars? Just a guess as I don't use SQLServer 2000 but they are required by the MS SQLServer driver according to the documentation.

                OK, let me take a shot at answering this,

                Here's my setup

                Apache, JBOSS 3.2.0 bundled with Tomcat, SQLServer2000 on W2K Server.

                %JBOSS_DIST is the JBOSS install directory (in my case D:\jboss-3.2.0_tomcat-4.1.24\)

                The steps I followed were :

                1. Download and install the microsoft jdbc driver.

                2. Copy the msbase.jar, mssqlserver.jar and msutil.jar files from the C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib directory(or wherever you installed it) to the %JBOSS_DIST%\server\default\lib directory.

                3. Copy the mssql-ds.xml file from the %JBOSS_DIST%\docs\examples\jca directory into the %JBOSS_DIST%\server\default\deploy directory.

                4. Modify the mssql-ds.xml file with the appropriate values.
                Eg.
                here's what my mssql-ds.xml file looks like

                <local-tx-datasource>
                <jndi-name>MSSQLDS</jndi-name>
                <connection-url>jdbc:sqlserver://yourSQLServerIP:1433/yourDatabase</connection-url>
                <driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>
                <user-name>yourUser</user-name>
                yourPwd
                <min-pool-size>2</min-pool-size>
                <max-pool-size>10</max-pool-size>
                </local-tx-datasource>



                Note: The name of the -ds.xml file should correspond to the jndi-name value.

                5. Add the datasource to the %JBOSS_DIST%\server\default\conf\standardjbosscmp-jdbc.xml file. Just the and <datasource-mapping> elements should be sufficient.

                This is what i used:

                MSSQLDS
                <datasource-mapping>MS SQLSERVER</datasource-mapping>

                6. Do the same as in step 5 in the %JBOSS_DIST%\server\default\conf\standardjaws.xml file.



                Now in your code you can access the Connection pool like so :

                Context ctx = new InitialContext();
                DataSource ds = (DataSource)ctx.lookup("java:/MSSQLDS");
                Connection con = ds.getConnection();
                ......

                or

                If you want to use direct JDBC access :

                Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
                Connection con = DriverManager.getConnection("jdbc:microsoft:sqlserver://yourSQLServerIP:1433;DatabaseName=yourDB;User=yourUser;Password=yourPwd");
                .......

                If you want do EJB you are on your own, haven't tried as yet.

                This is just what worked for me after a bit of trial and error today

                JBOSS/SQLServer guru's feel free to correct this as necessary.

                  Thats it, thx.

                  Why does he throw a ClassNotFoundException, when the SQLDriver from M$ is in the mssqlserver.jar and this file is in the lib directory? Why the mssqlserver.jar file is not loaded by the classloader?

                  regards
