Configure the CData JDBC Driver for Bing Search 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 Bing Search results from a connection pool in Tomcat.

Connect to Bing Search Results 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 Bing, set the ApiKey connection property. To obtain the API key, sign into Microsoft Cognitive Services and register for the Bing Search APIs.

   Two API keys are then generated; select either one.

   When querying tables, the SearchTerms parameter must be supplied in the WHERE clause.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.bing.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/bing" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.bing.BingDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:bing:APIKey=MyAPIKey;" maxActive="20" maxIdle="10" maxWait="-1" />

   To allow a single application to access Bing Search results, 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 Bing Search for all applications.

3. Add a reference to the resource to the web.xml for the application. Bing Search results JSP jdbc/Bing 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/Bing"); Connection conn = ds.getConnection();
