Configure the CData JDBC Driver for Workday in 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 Workday data from a connection pool in Tomcat.

Getting Started

---

Connect to Workday 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.

   To connect to Workday, users need to find the Tenant and BaseURL and then select their API type.

   Obtaining the BaseURL and Tenant

   To obtain the BaseURL and Tenant properties, log into Workday and search for "View API Clients." On this screen, you'll find the Workday REST API Endpoint, a URL that includes both the BaseURL and Tenant.

   The format of the REST API Endpoint is: https://domain.com/subdirectories/mycompany, where:

   • https://domain.com/subdirectories/ is the BaseURL.
   • mycompany (the portion of the url after the very last slash) is the Tenant.
   For example, in the REST API endpoint https://wd3-impl-services1.workday.com/ccx/api/v1/mycompany, the BaseURL is https://wd3-impl-services1.workday.com and the Tenant is mycompany.

   Using ConnectionType to Select the API

   The value you use for the ConnectionType property determines which Workday API you use. See our Community Article for more information on Workday connectivity options and best practices.

   API	ConnectionType Value
   WQL	WQL
   Reports as a Service	Reports
   REST	REST
   SOAP	SOAP

   
   

   Authentication

   Your method of authentication depends on which API you are using.

   • WQL, Reports as a Service, REST: Use OAuth authentication.
   • SOAP: Use Basic or OAuth authentication.

   See the Help documentation for more information on configuring OAuth with Workday.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.workday.jar
   

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

   👁 Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)
   

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

   <Resource name="jdbc/workday" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.workday.WorkdayDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:workday:User=myuser;Password=mypassword;Tenant=mycompany_gm1;BaseURL=https://wd3-impl-services1.workday.com;ConnectionType=WQL;InitiateOAuth=GETANDREFRESH;" maxActive="20" maxIdle="10" maxWait="-1" />
   

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

3. Add a reference to the resource to the web.xml for the application.

    Workday data JSP
    jdbc/Workday
    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/Workday");
   Connection conn = ds.getConnection();

The steps above show how to connect to Workday data in a simple connection pooling scenario. For more use cases and information, see the JNDI Datasource How-To in the Tomcat documentation.
