Connect to SAP Fieldglass Data from a Connection Pool in Jetty

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

   <Configure id='sapfieldglassdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="sapfieldglassdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="sapfieldglassdemo"/></Arg> <Arg>jdbc/sapfieldglassdb</Arg> <Arg> <New class="cdata.jdbc.sapfieldglass.SAPFieldglassDriver"> <Set name="url">jdbc:sapfieldglass:</Set> <Set name="EnvironmentURL">'https://myinstance.com'</Set> <Set name="Username">myuser</Set> <Set name="Password">mypassword</Set> <Set name="APIKey">xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

   To authenticate, you will need to specify the Username, Password, APIKey, and EnvironmentURL connection properties.

   To obtain an APIKey, log in to the SAP API Business Hub and click on Get API Key.

4. Configure the resource in the Web.xml:

   jdbc/sapfieldglassdb javax.sql.DataSource Container

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