Connect to SAP ByDesign Data from a Connection Pool in Jetty

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

   <Configure id='sapbydesigndemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="sapbydesigndemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="sapbydesigndemo"/></Arg> <Arg>jdbc/sapbydesigndb</Arg> <Arg> <New class="cdata.jdbc.sapbydesign.SAPByDesignDriver"> <Set name="url">jdbc:sapbydesign:</Set> <Set name="URL">https://my999999.sapbydesign.com</Set> <Set name="User">username</Set> <Set name="Password">password</Set> <Set name="CustomService">servicename</Set> </New> </Arg> </New> </Configure>

   Set the following connection properties to connect to SAP ByDesign.

   • Url: Set this to the Url of your SAP ByDesign site. For example, https://test.sapbydesign.com
   • User: Set this to the username of your account.
   • Password: Set this to the password of your account.
   • CustomService or AnalyticsService: Only one of these must be specified. If you have a custom service you want to retrieve data from, specify CustomService. If you want to retrieve the reports of a analytical service, specify AnalyticsService.
     If neither is specified, 'cc_home_analytics.svc' will used as a default for the AnalyticsService property. If you are not sure what service to specify, you can always query the Services view to list available services.

4. Configure the resource in the Web.xml:

   jdbc/sapbydesigndb javax.sql.DataSource Container

5. You can then access SAP ByDesign with a lookup to java:comp/env/jdbc/sapbydesigndb: InitialContext ctx = new InitialContext(); DataSource mysapbydesign = (DataSource)ctx.lookup("java:comp/env/jdbc/sapbydesigndb");
