Connect to ServiceNow Data from a Connection Pool in Jetty

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

   <Configure id='servicenowdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="servicenowdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="servicenowdemo"/></Arg> <Arg>jdbc/servicenowdb</Arg> <Arg> <New class="cdata.jdbc.servicenow.ServiceNowDriver"> <Set name="url">jdbc:servicenow:</Set> <Set name="OAuthClientId">MyOAuthClientId</Set> <Set name="OAuthClientSecret">MyOAuthClientSecret</Set> <Set name="Username">MyUsername</Set> <Set name="Password">MyPassword</Set> <Set name="Instance">MyInstance</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

   ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.

   See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

4. Configure the resource in the Web.xml:

   jdbc/servicenowdb javax.sql.DataSource Container

5. You can then access ServiceNow with a lookup to java:comp/env/jdbc/servicenowdb: InitialContext ctx = new InitialContext(); DataSource myservicenow = (DataSource)ctx.lookup("java:comp/env/jdbc/servicenowdb");
