Connect to JotForm Data from a Connection Pool in Jetty

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

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

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

   JotForm API Profile Settings

   You will need to find your JotForm API Key in order to authenticate. To obtain an API Key, go to 'My Account' > 'API Section' > 'Create a New API Key'. Once you've created your new API Key, you can set it in the ProfileSettings connection property.

   Custom Enterprise API Domains

   Enterprise customers of JotForm are given custom API domains to connect to, rather than the default 'api.jotform.com' domain. If you are an enterprise JotForm customer, then set Domain to you custom API hostname, such as 'your-domain.com' or 'subdomain.jotform.com', inside the ProfileSettings connection property. Conversely, if you do not have a custom domain and still need to connect to 'api.jotform.com', then leave Domain undefined and set only APIKey.

4. Configure the resource in the Web.xml:

   jdbc/jotformdb javax.sql.DataSource Container

5. You can then access JotForm with a lookup to java:comp/env/jdbc/jotformdb: InitialContext ctx = new InitialContext(); DataSource myjotform = (DataSource)ctx.lookup("java:comp/env/jdbc/jotformdb");

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.
