Connect to Flowlu Data from a Connection Pool in Jetty

The CData JDBC driver for Flowlu is easy to integrate with Java Web applications. This article shows how to efficiently connect to Flowlu data in Jetty by configuring the driver for connection pooling. You will configure a JNDI resource for Flowlu 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 Flowlu data source at the level of the Web app, in WEB-INF\jetty-env.xml.

   
   <Configure id='flowludemo' class="org.eclipse.jetty.webapp.WebAppContext">
       <New id="flowludemo" class="org.eclipse.jetty.plus.jndi.Resource">
       <Arg><Ref refid="flowludemo"/></Arg>
       <Arg>jdbc/flowludb</Arg>
       <Arg>
         <New class="cdata.jdbc.api.APIDriver">
           <Set name="url">jdbc:api:</Set>
           <Set name="Profile">C:\profiles\Flowlu.apip</Set>
           <Set name="ProfileSettings">'APIKey</Set>
           <Set name="Company">your_company_subdomain'</Set>
         </New>
       </Arg>
     </New>
   </Configure>
   

   Start by setting the Profile connection property to the location of the Flowlu Profile on disk (e.g. C:\profiles\Flowlu.apip). Next, set the ProfileSettings connection property to the connection string for Flowlu (see below).

   Flowlu API Profile Settings

   In your Flowlu account, navigate to System Settings > API Settings > Create to generate an API key. Your Company name is the subdomain from your Flowlu account URL.

4. Configure the resource in the Web.xml:

   
     jdbc/flowludb
     javax.sql.DataSource
     Container
   
   

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

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