Connect to Zoho CRM Data from a Connection Pool in Jetty

The Zoho CRM JDBC Driver supports connection pooling: This article shows how to connect faster to Zoho CRM data from Web apps in Jetty.

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

    <Configure id='zohocrmdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="zohocrmdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="zohocrmdemo"/></Arg> <Arg>jdbc/zohocrmdb</Arg> <Arg> <New class="cdata.jdbc.zohocrm.ZohoCRMDriver"> <Set name="url">jdbc:zohocrm:</Set> <Set name="AuthToken">2ad3b3e719f6bed7368e5e7e26e4f988</Set> </New> </Arg> </New> </Configure>

    You will need to obtain an AuthToken to authenticate to Zoho CRM. You can generate an AuthToken on the Zoho CRM website or by calling the GetAuthToken stored procedure. Note that when you generate an AuthToken from Zoho CRM, you can only generate an AuthToken for your user account. You can generate AuthTokens for other user accounts by calling GetAuthToken.

    See the "Getting Started" chapter in the help documentation for a guide.

  4. Configure the resource in the Web.xml:

    jdbc/zohocrmdb javax.sql.DataSource Container
  5. You can then access Zoho CRM with a lookup to java:comp/env/jdbc/zohocrmdb: InitialContext ctx = new InitialContext(); DataSource myzohocrm = (DataSource)ctx.lookup("java:comp/env/jdbc/zohocrmdb");
