Connect to Browserless Data from a Connection Pool in Jetty

The CData JDBC driver for Browserless is easy to integrate with Java Web applications. This article shows how to efficiently connect to Browserless data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Browserless in Jetty.

Configure the JDBC Driver for Salesforce as a JNDI Data Source

Follow the steps below to connect to Salesforce from Jetty.

1. 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
   

2. Add the CData and license file, located in the lib subfolder of the installation directory, into the lib subfolder of the context path.

3. Declare the resource and its scope. Enter the required connection properties in the resource declaration. This example declares the Browserless data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   
   <Configure id='browserlessdemo' class="org.eclipse.jetty.webapp.WebAppContext">
       <New id="browserlessdemo" class="org.eclipse.jetty.plus.jndi.Resource">
       <Arg><Ref refid="browserlessdemo"/></Arg>
       <Arg>jdbc/browserlessdb</Arg>
       <Arg>
         <New class="cdata.jdbc.api.APIDriver">
           <Set name="url">jdbc:api:</Set>
           <Set name="Profile">C:\profiles\Browserless.apip</Set>
           <Set name="AuthScheme">APIKey</Set>
           <Set name="ProfileSettings">"ApiKey</Set>
         </New>
       </Arg>
     </New>
   </Configure>
   

   Browserless uses HTTP API token authentication. Your Browserless API token is sent as the token query parameter on every request. You can generate or view your token in the Browserless dashboard at https://account.browserless.io/.

   Using ApiKey Authentication

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

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your Browserless API token.

   Example connection string:

   Profile=C:\profiles\Browserless.apip;AuthScheme=APIKey;ProfileSettings="ApiKey=your_api_token";
   

4. Configure the resource in the Web.xml:

   
     jdbc/browserlessdb
     javax.sql.DataSource
     Container
   
   

5. You can then access Browserless with a lookup to java:comp/env/jdbc/browserlessdb:

   InitialContext ctx = new InitialContext();
   DataSource mybrowserless = (DataSource)ctx.lookup("java:comp/env/jdbc/browserlessdb");

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.
