Configure the CData JDBC Driver for Salesforce in a Connection Pool in Tomcat

Connect to Salesforce 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 Salesforce data from a connection pool in Tomcat.

Connect to Salesforce 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.

    There are several authentication methods available for connecting to Salesforce: Login, OAuth, and SSO. The Login method requires you to have the username, password, and security token of the user.

    If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication.

    SSO (single sign-on) can be used by setting the SSOProperties, SSOLoginUrl, and TokenUrl connection properties, which allow you to authenticate to an identity provider. See the "Getting Started" chapter in the help documentation for more information.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.salesforce.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/salesforce" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.salesforce.SalesforceDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:salesforce:User=username;Password=password;SecurityToken=Your_Security_Token;" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access Salesforce 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 Salesforce for all applications.

  3. Add a reference to the resource to the web.xml for the application. Salesforce data JSP jdbc/Salesforce 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/Salesforce"); Connection conn = ds.getConnection();
