Connect to PayPal Data from a Connection Pool in Jetty

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

   <Configure id='paypaldemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="paypaldemo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="paypaldemo"/></Arg> <Arg>jdbc/paypaldb</Arg> <Arg> <New class="cdata.jdbc.paypal.PayPalDriver"> <Set name="url">jdbc:paypal:</Set> <Set name="Schema">SOAP</Set> <Set name="Username">sandbox-facilitator_api1.test.com</Set> <Set name="Password">xyz123</Set> <Set name="Signature">zx2127</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

   The provider surfaces tables from two PayPal APIs. The APIs use different authentication methods.

   • The REST API uses the OAuth standard. To authenticate to the REST API, you will need to set the OAuthClientId, OAuthClientSecret, and CallbackURL properties.
   • The Classic API requires Signature API credentials. To authenticate to the Classic API, you will need to obtain an API username, password, and signature.

   See the "Getting Started" chapter of the help documentation for a guide to obtaining the necessary API credentials.

   To select the API you want to work with, you can set the Schema property to REST or SOAP. By default the SOAP schema will be used.

   For testing purposes you can set UseSandbox to true and use sandbox credentials.

4. Configure the resource in the Web.xml:

   jdbc/paypaldb javax.sql.DataSource Container

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