Connect to Presto Data from a Connection Pool in JBoss

Integrate Presto data into Java servlets: Use the Management Console in JBoss to install the Presto JDBC Driver.

CData JDBC drivers can be configured in JBoss by following the standard procedure for connection pooling. This article details how to access Presto data from a connection pool in JBoss applications. This article details how to use the JBoss Management Interface to configure the CData JDBC Driver for Presto. You will then access Presto data from a connection pool.

Create a JDBC Data Source for Presto from the Management Console

Follow the steps below to add the driver JAR and define required connection properties.

  1. In the Runtime menu, select the Domain or Server menu, depending on whether you are deploying to a managed domain or to a stand-alone server, and click "Manage deployments" to open the Deployments page.
  2. Click Add. In the resulting wizard, add the JAR file and license for the driver, located in the lib subfolder of the installation directory. Finish the wizard with the defaults, select the driver, and click Enable.
  3. In the Configuration menu, click Subsystems -> Connector -> Datasources. This opens the JDBC Datasources page.
  4. Click Add and, in the resulting wizard, enter a name for the driver and the JNDI name. For example: java:jboss/root/jdbc/Presto
  5. Select the driver that you added above.
  6. Enter the JDBC URL and the username and password. The syntax of the JDBC URL is jdbc:presto: followed by a semicolon-separated list of connection properties.

    Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

    To enable TLS/SSL, set UseSSL to true.

    Authenticating with LDAP

    In order to authenticate with LDAP, set the following connection properties:

    • AuthScheme: Set this to LDAP.
    • User: The username being authenticated with in LDAP.
    • Password: The password associated with the User you are authenticating against LDAP with.

    Authenticating with Kerberos

    In order to authenticate with KERBEROS, set the following connection properties:

    • AuthScheme: Set this to KERBEROS.
    • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
    • KerberosRealm: The Kerberos Realm used to authenticate the user with.
    • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
    • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
    • User: The user who is authenticating to Kerberos.
    • Password: The password used to authenticate to Kerberos.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Presto JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.presto.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    A typical connection string is below:

    jdbc:presto:Server=127.0.0.1;Port=8080;
  7. Test the connection and finish the wizard. Select the Presto data source and click Enable.
