Connect to Dynamics GP Data from a Connection Pool in Jetty

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

   <Configure id='dynamicsgpdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="dynamicsgpdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="dynamicsgpdemo"/></Arg> <Arg>jdbc/dynamicsgpdb</Arg> <Arg> <New class="cdata.jdbc.dynamicsgp.DynamicsGPDriver"> <Set name="url">jdbc:dynamicsgp:</Set> <Set name="CompanyId">mycompanyId</Set> <Set name="user">myuser</Set> <Set name="password">mypassword</Set> <Set name="URL">http://{servername}:{port}/Dynamics/GPService</Set> </New> </Arg> </New> </Configure>

   To authenticate set the User and Password connection properties.

   To connect set the URL to the Web services endpoint; for example, http://{servername}:{port}/Dynamics/GPService. Additionally, set CompanyId; you can obtain this value in the company setup window: Click Tools -> Setup -> Company.

   By default, data summaries are not returned to save performance. Set LookupIds to true to return details such as line items; however, note that entities must be retrieved one at a time.

4. Configure the resource in the Web.xml:

   jdbc/dynamicsgpdb javax.sql.DataSource Container

5. You can then access Dynamics GP with a lookup to java:comp/env/jdbc/dynamicsgpdb: InitialContext ctx = new InitialContext(); DataSource mydynamicsgp = (DataSource)ctx.lookup("java:comp/env/jdbc/dynamicsgpdb");
