Connect to Wave Financial Data from a Connection Pool in Jetty

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

   <Configure id='wavefinancialdemo' class="org.eclipse.jetty.webapp.WebAppContext">
    <New id="wavefinancialdemo" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg><Ref refid="wavefinancialdemo"/></Arg>
    <Arg>jdbc/wavefinancialdb</Arg>
    <Arg>
    <New class="cdata.jdbc.wavefinancial.WaveFinancialDriver">
    <Set name="url">jdbc:wavefinancial:</Set>
    <Set name="InitiateOAuth">GETANDREFRESH</Set>
    </New>
    </Arg>
    </New>
   </Configure>
   

   Connect using the API Token

   You can connect to Wave Financial by specifying the APIToken You can obtain an API Token using the following steps:

   1. Log in to your Wave account and navigate to "Manage Applications" in the left pane.
   2. Select the application that you would like to create a token for. You may need to create an application first.
   3. Click the "Create token" button to generate an APIToken.

   Connect using OAuth

   If you wish, you can connect using the embedded OAuth credentials. See the Help documentation for more information.

4. Configure the resource in the Web.xml:

    jdbc/wavefinancialdb
    javax.sql.DataSource
    Container
   
   

5. You can then access Wave Financial with a lookup to java:comp/env/jdbc/wavefinancialdb:

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