IBM Cloud SQL Query JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with IBM Cloud SQL Query.

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

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

    <Configure id='ibmcloudsqldemo' class="org.eclipse.jetty.webapp.WebAppContext"> <New id="ibmcloudsqldemo" class=""> <Arg><Ref refid="ibmcloudsqldemo"/></Arg> <Arg>jdbc/ibmcloudsqldb</Arg> <Arg> <New class="cdata.jdbc.ibmcloudsqlquery.IBMCloudSQLQueryDriver"> <Set name="url">jdbc:ibmcloudsqlquery:</Set> <Set name="Api Key">MyAPIKey</Set> <Set name="Instance CRN">myInstanceCRN</Set> <Set name="Region">myRegion</Set> <Set name="Schema">mySchema</Set> <Set name="OAuth Client Id">myOAuthClientId</Set> <Set name="OAuth Client Secret">myOAuthClientSecret</Set> <Set name="InitiateOAuth">GETANDREFRESH</Set> </New> </Arg> </New> </Configure>

    IBM Cloud SQL uses the OAuth and HMAC authentication standards. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

  4. Configure the resource in the Web.xml:

    jdbc/ibmcloudsqldb javax.sql.DataSource Container
  5. You can then access IBM Cloud SQL Query with a lookup to java:comp/env/jdbc/ibmcloudsqldb: InitialContext ctx = new InitialContext(); DataSource myibmcloudsql = (DataSource)ctx.lookup("java:comp/env/jdbc/ibmcloudsqldb");

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.
