Connect to Reckon Data from a Connection Pool in Jetty

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

   <Configure id='reckondemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="reckondemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="reckondemo"/></Arg> <Arg>jdbc/reckondb</Arg> <Arg> <New class="cdata.jdbc.reckon.ReckonDriver"> <Set name="url">jdbc:reckon:</Set> <Set name="User">RCUser</Set> <Set name="Password">RCUserPassword</Set> <Set name="URL">http://remotehost:8166</Set> </New> </Arg> </New> </Configure>

   When you are connecting to a local Reckon instance, you do not need to set any connection properties.

   Requests to Reckon are made through the Remote Connector. The Remote Connector runs on the same machine as Reckon and accepts connections through a lightweight, embedded Web server. The server supports SSL/TLS, enabling users to connect securely from remote machines.

   The first time you connect to your company file, you will need to authorize the Remote Connector with Reckon. See the "Getting Started" chapter of the help documentation for a guide.

4. Configure the resource in the Web.xml:

   jdbc/reckondb javax.sql.DataSource Container

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