Slack JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with Slack.

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

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

    <Configure id='slackdemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="slackdemo" class=""> <Arg><Ref refid="slackdemo"/></Arg> <Arg>jdbc/slackdb</Arg> <Arg> <New class="cdata.jdbc.slack.SlackDriver"> <Set name="url">jdbc:slack:</Set> <Set name="OAuthClientId">MyOAuthClientId</Set> <Set name="OAuthClientSecret">MyOAuthClientSecret</Set> <Set name="CallbackURL">http://localhost:33333</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure> Slack uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Getting Started section of the help documentation for an authentication guide.
  4. Configure the resource in the Web.xml:

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

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.
