Connect to Sage 200 Data from a Connection Pool in Jetty

The CData JDBC driver for Sage 200 is easy to integrate with Java Web applications. This article shows how to efficiently connect to Sage 200 data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Sage 200 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 Sage 200 data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   <Configure id='sage200demo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="sage200demo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="sage200demo"/></Arg> <Arg>jdbc/sage200db</Arg> <Arg> <New class="cdata.jdbc.sage200.Sage200Driver"> <Set name="url">jdbc:sage200:</Set> <Set name="SubscriptionKey">12345</Set> <Set name="Schema">StandardUK</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>
   • Schema: Determines which Sage 200 edition you are connecting to. Specify either StandardUK or ProfessionalUK.
   • Subscription Key: Provides access to the APIs that are used to establish a connection. You will first need to log into the Sage 200 API website and subscribe to the API edition that matches your account. You can do so here: https://developer.columbus.sage.com/docs/services/api/uk. Afterwards, the subscription key may be found in your profile after logging into Sage 200.

4. Configure the resource in the Web.xml:

   jdbc/sage200db javax.sql.DataSource Container

5. You can then access Sage 200 with a lookup to java:comp/env/jdbc/sage200db: InitialContext ctx = new InitialContext(); DataSource mysage200 = (DataSource)ctx.lookup("java:comp/env/jdbc/sage200db");
