SQL Server data sources in JBoss AS 7

Last week, I set up a SQL Server 2008 data source on a JBoss AS 7.1.1 server, in order to be used by a Java EE application, so I’d like to share what I’ve learned.

The first step was to install the driver. There are two ways to do this, the quick one is simply to deploy the jdbc driver (sqljdbc4.jar) as a regular deployment, by typing this command in CLI (the name parameter is optional, but I found it useful):

deploy C:\software\drivers\sqljdbc4.jar –name=sqlserver

The second option is to install the jdbc driver as a core module, which it was what I finally did. This one was a bit more laborious. First of all, I turned off the server and I set up a directory structure under JBoss modules folder, in my case C:\jboss-as-7.1.1.Final\modules\com\microsoft\sqlserver\main, after that, I copied the driver sqljdbc4.jar there and I created a file called module.xml with the following content:

  <?xml version="1.0" encoding="UTF-8"?>
  <module xmlns="urn:jboss:module:1.0" name="com.microsoft.sqlserver">
    <resources>
      <resource-root path="sqljdbc4.jar"/>
    </resources>
    <dependencies>
      <module name="javax.api"/>
      <module name="javax.transaction.api"/>
    </dependencies>
  </module>

The key here is to create a directory structure that matches the module name. The final step of this option was to start the server and run the following CLI command:

/subsystem=datasources/jdbc-driver=sqlserver:add(driver-name=sqlserver,driver-module-name=com.microsoft.sqlserver,driver-xa-datasource-class-name=com.microsoft.sqlserver.jdbc.SQLServerXADataSource)

Once I had the driver configured, I created the data source by using this CLI command (for this sample, I set up a local SQL Server EXPRESS instance, with a test database and a test user):

data-source add –name=TestDS –jndi-name=java:/jdbc/Test –driver-name=sqlserver –connection-url=jdbc:sqlserver://localhost\SQLEXPRESS;databaseName=Test –user-name=test –password=test –min-pool-size=10 –max-pool-size=50 –pool-use-strict-min=true –pool-prefill=true –jta=true –use-ccm=true –prepared-statements-cache-size=32

 The data source has to be enabled:

data-source enable –name=TestDS

Finally, I tested the configuration with the following command:

/subsystem=datasources/data-source=TestDS/:test-connection-in-pool

Creating a XA data source was slightly different. The first step was to check out that my SQL Server installation was properly configured, by reviewing the chapter titled Configuration Instructions of this article. After that, I ran these commands:

xa-data-source add –name=TestDS–jndi-name=java:/jdbc/Test/XA –driver-name=sqlserver –user-name=test –password=test–min-pool-size=10 –max-pool-size=50 –pool-use-strict-min=true –pool-prefill=true –jta=true –use-ccm=true –prepared-statements-cache-size=32 –same-rm-override=false
/subsystem=datasources/xa-data-source=TestDS/xa-datasource-properties=ServerName:add(value=localhost\SQLEXPRESS)
/subsystem=datasources/xa-data-source=TestDS/xa-datasource-properties=DatabaseName:add(value=Test)
/subsystem=datasources/xa-data-source=TestDS/xa-datasource-properties=SelectMethod:add(value=cursor)
xa-data-source enable –name=TestDS
/subsystem=datasources/xa-data-source=TestDS/:test-connection-in-pool

A final tip, if you decide to deploy the driver, instead of installing it as a core module, you have to add the parameter –xa-datasource-class to the command xa-data-source add with the value com.microsoft.sqlserver.jdbc.SQLServerXADataSource

    Nice shot!

  2. fcosfc says:

    Later versions of JBoss Application Server (for example JBoss EAP 6.3 or Wildfly 8.2.1) allow to install the jdbc driver as a core module by executing the following CLI command:

    module add –name=com.microsoft.sqlserver –resources=[PATH TO JDBC DRIVER]/sqljdbc4.jar –dependencies=javax.api,javax.transaction.api
