SAS Data Sets JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with SAS Data Sets.



Connect to SAS Data Sets data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to SAS Data Sets data from a connection pool in Tomcat.

Connect to SAS Data Sets Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    Set the following connection properties to connect to your SAS DataSets files:

    • URI: Set this to the folder containing your .sas7bdat resources. Currently we only support local files.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the SAS Data Sets JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.sasdatasets.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/sasdatasets" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.sasdatasets.SASDataSetsDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:sasdatasets:URI=C:/myfolder;" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access SAS Data Sets data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to SAS Data Sets for all applications.

  3. Add a reference to the resource to the web.xml for the application. SAS Data Sets data JSP jdbc/SASDataSets javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/SASDataSets"); Connection conn = ds.getConnection();

The steps above show how to connect to SAS Data Sets data in a simple connection pooling scenario. For more use cases and information, see the JNDI Datasource How-To in the Tomcat documentation.
