If you're using OpenXava 7.0 or newer look at the new instructions

Configuring your OpenXava 6.x (or older) application to go against MS SQL Server is very simple, basically you have to install the JDBC driver for MS SQL Server and define correctly the datasource. You don't need to touch any code of your application.

We assume you have already installed and running MS SQL Server.

Download the JDBC driver for MS SQL Server

Download the MS SQL Server driver from here: https://docs.microsoft.com/sql/connect/jdbc/download-microsoft-jdbc-driver-for-sql-server

You will download a file like this: sqljdbc_7.4.1.0_enu.exe (the version numbers may vary) that is a self-extracting file for Windows or sqljdbc_7.4.1.0_enu.tar.gz for Linux/Mac. Uncompress it to find inside a file called mssql-jdbc-7.4.1.jre8.jar (or so), this last file, the .jar, is the JDBC controller we're going to use.

Create a classpath variable in Eclipse

In order you can connect to MS SQL Server from Eclipse we're going to declare a classpath variable that points to the MS SQL Server JDBC driver, so you can use it in any project you need easily. For that, in Eclipse go to Window > Preferences > Java > Build Path > Classpath Variables where you can add the new variable:

You can call the variable MSSQLSERVER_DRIVER instead of DB_DRIVER if your prefer. The path is the path of the JDBC driver, in our case the path of mssql-jdbc-7.4.1.jre8.jar we have just downloaded.

Add the DB_DRIVER variable to your Eclipse project

In the project you're going to use MS SQL Server you have to add the variable declared above. Click with right mouse button on your project and then choose Java Build Path > Configure Build Path...:

With this we have the driver available for the development environment.

Add the JDBC driver to the production Tomcat

Adding the driver in production is much easier. Copy mssql-jdbc-7.4.1.jre8.jar to the lib folder of your Tomcat. Done.

Adjust your datasource definition

For development edit web/META-INF/context.xml of your Eclipse project, and for production edit conf/context.xml of your Tomcat to adjust the datasource to point to MS SQL Server, something like this:

<Resource name="jdbc/MyAppDS" auth="Container"
	type="javax.sql.DataSource"
	maxTotal="100" maxIdle="20" maxWaitMillis="10000"
	username="root" password="ao49fmsk"
	driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
	url="jdbc:sqlserver://localhost:1433;databaseName=myappdb"/>

The differences are the driverClassName and the url. The final part of the url, myappdb in this example, is the name of your MS SQL Server database. Obviously, instead of localhost you should put the address of the server that hosts MS SQL Server, and also put the correct username and password.
