Connect to Asana Data from a Connection Pool in Jetty

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

   <Configure id='asanademo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="asanademo" class="org.eclipse.jetty.plus.jndi.Resource"> <Arg><Ref refid="asanademo"/></Arg> <Arg>jdbc/asanadb</Arg> <Arg> <New class="cdata.jdbc.asana.AsanaDriver"> <Set name="url">jdbc:asana:</Set> <Set name="OAuthClientId">YourClientId</Set> <Set name="OAuthClientSecret">YourClientSecret</Set> <Set name="CallbackURL">'http://localhost:33333'</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

   You can optionally set the following to refine the data returned from Asana.

   • WorkspaceId: Set this to the globally unique identifier (gid) associated with your Asana Workspace to only return projects from the specified workspace. To get your workspace id, navigate to https://app.asana.com/api/1.0/workspaces while logged into Asana. This displays a JSON object containing your workspace name and Id.
   • ProjectId: Set this to the globally unique identifier (gid) associated with your Asana Project to only return data mapped under the specified project. Project IDs can be found in the URL of your project's Overview page. This will be the numbers directly after /0/.

   Connect Using OAuth Authentication

   You must use OAuth to authenticate with Asana. OAuth requires the authenticating user to interact with Asana using the browser. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

4. Configure the resource in the Web.xml:

   jdbc/asanadb javax.sql.DataSource Container

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

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.
