Connect to SAP Business Warehouse Data from a Connection Pool in Jetty

The CData JDBC driver for SAP Business Warehouse is easy to integrate with Java Web applications. This article shows how to efficiently connect to SAP Business Warehouse data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for SAP Business Warehouse 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 SAP Business Warehouse data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   
   <Configure id='sapbusinesswarehousedemo' class="org.eclipse.jetty.webapp.WebAppContext">
       <New id="sapbusinesswarehousedemo" class="org.eclipse.jetty.plus.jndi.Resource">
       <Arg><Ref refid="sapbusinesswarehousedemo"/></Arg>
       <Arg>jdbc/sapbusinesswarehousedb</Arg>
       <Arg>
         <New class="cdata.jdbc.sapbusinesswarehouse.SAPBusinessWarehouseDriver">
           <Set name="url">jdbc:sapbusinesswarehouse:</Set>
           <Set name="URL">https://mysapserver:8000</Set>
           <Set name="AuthScheme">Basic</Set>
           <Set name="User">username</Set>
           <Set name="Password">password</Set>
         </New>
       </Arg>
     </New>
   </Configure>
   

   To connect to SAP Business Warehouse, set the URL property to a valid SAP Business Warehouse server base URL. The driver must connect to SAP Business Warehouse instances hosted over HTTP with XMLA access.

   The driver supports the following authentication schemes via the AuthScheme property:

   • None: Anonymous authentication, if available on the server.
   • Basic: Set User and Password and set AuthScheme to Basic.
   • Kerberos: See the Using Kerberos section of the help documentation for the required Kerberos properties.

   By default, the driver attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

4. Configure the resource in the Web.xml:

   
     jdbc/sapbusinesswarehousedb
     javax.sql.DataSource
     Container
   
   

5. You can then access SAP Business Warehouse with a lookup to java:comp/env/jdbc/sapbusinesswarehousedb:

   InitialContext ctx = new InitialContext();
   DataSource mysapbusinesswarehouse = (DataSource)ctx.lookup("java:comp/env/jdbc/sapbusinesswarehousedb");

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.
