Connect to Microsoft Dataverse 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 Microsoft Dataverse data from a connection pool in Tomcat.
About Microsoft Dataverse Data Integration
CData provides the easiest way to access and integrate live data from Microsoft Dataverse (formerly the Common Data Service). Customers use CData connectivity to:
- Access both Dataverse Entities and Dataverse system tables to work with exactly the data they need.
- Authenticate securely with Microsoft Dataverse in a variety of ways, including Azure Active Directory, Azure Managed Service Identity credentials, and Azure Service Principal using either a client secret or a certificate.
- Use SQL stored procedures to manage Microsoft Dataverse entities - listing, creating, and removing associations between entities.
CData customers use our Dataverse connectivity solutions for a variety of reasons, whether they're looking to replicate their data into a data warehouse (alongside other data sources)or analyze live Dataverse data from their preferred data tools inside the Microsoft ecosystem (Power BI, Excel, etc.) or with external tools (Tableau, Looker, etc.).
Getting Started
Connect to Microsoft Dataverse Data through a Connection Pool in Tomcat
- 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.
- Add a definition of the resource to the context. Specify the JDBC URL here.
You can connect without setting any connection properties for your user credentials. Below are the minimum connection properties required to connect.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- OrganizationUrl: Set this to the organization URL you are connecting to, such as https://myorganization.crm.dynamics.com.
- Tenant (optional): Set this if you wish to authenticate to a different tenant than your default. This is required to work with an organization not on your default Tenant.
When you connect the Common Data Service OAuth endpoint opens in your default browser. Log in and grant permissions. The OAuth process completes automatically.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Microsoft Dataverse JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.cds.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/cds" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.cds.CDSDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:cds:OrganizationUrl=https://myaccount.crm.dynamics.com/InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />
To allow a single application to access Microsoft Dataverse 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 Microsoft Dataverse for all applications.
- Add a reference to the resource to the web.xml for the application.
Microsoft Dataverse data JSP jdbc/CDS javax.sql.DataSource Container -
Initialize connections from the connection pool:
Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/CDS"); Connection conn = ds.getConnection();
