SAS Data Sets JDBC Driver

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

The SAS Data Sets JDBC Driver supports connection pooling: This article shows how to connect faster to SAS Data Sets data from Web apps in Jetty.

The CData JDBC driver for SAS Data Sets is easy to integrate with Java Web applications. This article shows how to efficiently connect to SAS Data Sets data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for SAS Data Sets in Jetty.

Configure the JDBC Driver for Salesforce as a JNDI Data Source

Follow the steps below to connect to Salesforce from Jetty.

  1. Enable the JNDI module for your Jetty base. The following command enables JNDI from the command-line:

    java -jar ../start.jar --add-to-startd=jndi
  2. Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.
  3. Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the SAS Data Sets data source at the level of the Web app, in WEB-INF\jetty-env.xml.

    <Configure id='sasdatasetsdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="sasdatasetsdemo" class=""> <Arg><Ref refid="sasdatasetsdemo"/></Arg> <Arg>jdbc/sasdatasetsdb</Arg> <Arg> <New class="cdata.jdbc.sasdatasets.SASDataSetsDriver"> <Set name="url">jdbc:sasdatasets:</Set> <Set name="URI">C:/myfolder</Set> </New> </Arg> </New> </Configure>

    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.
  4. Configure the resource in the Web.xml:

    jdbc/sasdatasetsdb javax.sql.DataSource Container
  5. You can then access SAS Data Sets with a lookup to java:comp/env/jdbc/sasdatasetsdb: InitialContext ctx = new InitialContext(); DataSource mysasdatasets = (DataSource)ctx.lookup("java:comp/env/jdbc/sasdatasetsdb");

The steps above show how to configure the driver in a simple connection pooling scenario. For more use cases and information, see the Working with Jetty JNDI chapter in the Jetty documentation.
