Configure the CData JDBC Driver for SAP Business Warehouse in 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 SAP Business Warehouse data from a connection pool in Tomcat.

Connect to SAP Business Warehouse 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.

   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.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.sapbusinesswarehouse.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/sapbusinesswarehouse"   auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.sapbusinesswarehouse.SAPBusinessWarehouseDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:sapbusinesswarehouse:URL=https://mysapserver:8000;AuthScheme=Basic;User=username;Password=password;" maxActive="20" maxIdle="10" maxWait="-1" />
   

   To allow a single application to access SAP Business Warehouse 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 SAP Business Warehouse for all applications.

3. Add a reference to the resource to the web.xml for the application.

   
     SAP Business Warehouse data JSP
     jdbc/SAPBusinessWarehouse
     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/SAPBusinessWarehouse");
   Connection conn = ds.getConnection();
