Connect to Kintone Data from a Connection Pool in Jetty

The Kintone JDBC Driver supports connection pooling: This article shows how to connect faster to Kintone data from Web apps in Jetty.

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

    <Configure id='kintonedemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="kintonedemo" class=""> <Arg><Ref refid="kintonedemo"/></Arg> <Arg>jdbc/kintonedb</Arg> <Arg> <New class="cdata.jdbc.kintone.KintoneDriver"> <Set name="url">jdbc:kintone:</Set> <Set name="User">myuseraccount</Set> <Set name="Password">mypassword</Set> <Set name="Url"></Set> <Set name="GuestSpaceId">myspaceid</Set> </New> </Arg> </New> </Configure>

    In addition to the authentication values, set the following parameters to connect to and retrieve data from Kintone:

    • Url: The URL of your account.
    • GuestSpaceId: Optional. Set this when using a guest space.

    Authenticating with Kintone

    Kintone supports the following authentication methods.

    Using Password Authentication

    You must set the following to authenticate:

    • User: The username of your account.
    • Password: The password of your account.

    Using Basic Authentication

    If the basic authentication security feature is set on the domain, supply the additional login credentials with BasicAuthUser and BasicAuthPassword. Basic authentication requires these credentials in addition to User and Password.

    Using Client SSL

    Instead of basic authentication, you can specify a client certificate to authenticate. Set SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword. Additionally, set User and Password to your login credentials.

  4. Configure the resource in the Web.xml:

    jdbc/kintonedb javax.sql.DataSource Container
  5. You can then access Kintone with a lookup to java:comp/env/jdbc/kintonedb: InitialContext ctx = new InitialContext(); DataSource mykintone = (DataSource)ctx.lookup("java:comp/env/jdbc/kintonedb");

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.
