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

Connect to ZeroBounce 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.

   Using API Key Authentication

   ZeroBounce uses API key authentication. To obtain an API key:

   1. Log in to your ZeroBounce account at https://app.zerobounce.net
   2. Navigate to the API tab in your account dashboard
   3. Copy the API key displayed on the page

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.
   Set the following in the ProfileSettings connection property:
   • APIKey: Set this to your ZeroBounce API key.

   Example Connection String

   Profile=C:\profiles\ZeroBounce.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 ZeroBounce 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\ZeroBounce.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";" maxActive="20" maxIdle="10" maxWait="-1" />
   

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

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

   
     ZeroBounce 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();

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