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

Connect to CloudConvert 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.

   CloudConvert uses API key authentication. Your CloudConvert API key is used to authenticate requests as a Bearer token. You can generate or view your keys at https://cloudconvert.com/dashboard/api/v2/keys.

   Using API Key Authentication

   After setting the following connection properties, you are ready to connect:

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your CloudConvert API key.

   Example connection string:

   Profile=C:\profiles\CloudConvert.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";
   

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.api.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/api"   auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.api.APIDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:api:Profile=C:\profiles\CloudConvert.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";" maxActive="20" maxIdle="10" maxWait="-1" />
   

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

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

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