The Google Search JDBC Driver supports connection pooling: This article shows how to connect faster to Google Search results from Web apps in Jetty.
The CData JDBC driver for Google Search is easy to integrate with Java Web applications. This article shows how to efficiently connect to Google Search results in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Google Search in Jetty.
Configure the JDBC Driver for Salesforce as a JNDI Data Source
Follow the steps below to connect to Salesforce from Jetty.
Enable the JNDI module for your Jetty base. The following command enables JNDI from the command-line:
java -jar ../start.jar --add-to-startd=jndi
- Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.
-
Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the Google Search data source at the level of the Web app, in WEB-INF\jetty-env.xml.
<Configure id='googlesearchdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="googlesearchdemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="googlesearchdemo"/></Arg> <Arg>jdbc/googlesearchdb</Arg> <Arg> <New class="cdata.jdbc.googlesearch.GoogleSearchDriver"> <Set name="url">jdbc:googlesearch:</Set> <Set name="CustomSearchId">def456</Set> <Set name="ApiKey">abc123</Set> </New> </Arg> </New> </Configure>
To search with a Google custom search engine, you need to set the CustomSearchId and ApiKey connection properties.
To obtain the CustomSearchId property, sign into Google Custom Search Engine and create a new search engine.
To obtain the ApiKey property, you must enable the Custom Search API in the Google API Console.
-
Configure the resource in the Web.xml:
jdbc/googlesearchdb javax.sql.DataSource Container -
You can then access Google Search with a lookup to java:comp/env/jdbc/googlesearchdb:
InitialContext ctx = new InitialContext(); DataSource mygooglesearch = (DataSource)ctx.lookup("java:comp/env/jdbc/googlesearchdb");

The steps above show how to configure the driver in a simple connection pooling scenario. For more use cases and information, see the Working with Jetty JNDI chapter in the Jetty documentation.
