Configure the CData JDBC Driver for Dynamics 365 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 Dynamics 365 data from a connection pool in Tomcat.

Getting Started

Connect to Dynamics 365 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.

   Edition and OrganizationUrl are required connection properties. The Dynamics 365 connector supports connecting to the following editions: CustomerService, FieldService, FinOpsOnline, FinOpsOnPremise, HumanResources, Marketing, ProjectOperations and Sales.

   For Dynamics 365 Business Central, use the separate Dynamics 365 Business Central driver.

   OrganizationUrl is the URL to your Dynamics 365 organization. For instance, https://orgcb42e1d0.crm.dynamics.com

   Built-in Connection String Designer

   For assistance in constructing the JDBC URL, use the connection string designer built into the Dynamics 365 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

   java -jar cdata.jdbc.dynamics365.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/dynamics365" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.dynamics365.Dynamics365Driver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:dynamics365:OrganizationUrl=https://myaccount.operations.dynamics.com/;Edition=Sales;InitiateOAuth=GETANDREFRESH;" maxActive="20" maxIdle="10" maxWait="-1" />
   

   To allow a single application to access Dynamics 365 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 Dynamics 365 for all applications.

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

    Dynamics 365 data JSP
    jdbc/Dynamics365
    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/Dynamics365");
   Connection conn = ds.getConnection();

The steps above show how to connect to Dynamics 365 data in a simple connection pooling scenario. For more use cases and information, see the JNDI Datasource How-To in the Tomcat documentation.
