Connect to Pushover Data from a Connection Pool in Jetty

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

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

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

   Pushover API Profile Settings

   Pushover uses API Key authentication. Your Pushover Application API Token is used to authenticate all requests. You can create and manage API tokens in the Pushover dashboard at pushover.net by registering an application under Settings > Your Applications.

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

   • AuthScheme: Set this to APIKey.
   • APIKey: Set this to your 30-character Pushover Application API Token.

4. Configure the resource in the Web.xml:

   
   
     jdbc/pushoverdb
     javax.sql.DataSource
     Container
   
   

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

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