Configure the CData JDBC Driver for Zoho CRM in a Connection Pool in Tomcat

Connect to Zoho CRM data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to Zoho CRM data from a connection pool in Tomcat.

Connect to Zoho CRM Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    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.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Zoho CRM JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.zohocrm.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/zohocrm" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.zohocrm.ZohoCRMDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:zohocrm:AuthToken=2ad3b3e719f6bed7368e5e7e26e4f988;" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Zoho CRM data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to Zoho CRM for all applications.

  3. Add a reference to the resource to the web.xml for the application. Zoho CRM data JSP jdbc/ZohoCRM javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/ZohoCRM"); Connection conn = ds.getConnection();
