Connect to DB2 Data in NetBeans

The CData JDBC Driver for DB2 integrates connectivity to live DB2 data in IDEs that support JDBC. The JDBC standard enables you to use built-in data access wizards and other tools supporting rapid development. This article shows how to connect to DB2 data in NetBeans. You will create a connection and edit and save DB2 data in the Table Editor.

Create a JDBC Data Source for DB2 in NetBeans

To create the JDBC data source, expand the Database node in the Service window, right-click the Drivers node, and select New Driver. In the New Driver wizard that results, enter the following information:

• Driver File(s): Click Add and, in the file explorer dialog that appears, select the cdata.jdbc.db2.jar file. The driver JAR is located in the lib subfolder of the installation directory.
• Driver Class: Click Find to search for the driver class inside the JAR. Then select cdata.jdbc.db2.DB2Driver from the menu.
• Name: Enter the name for the driver.

Define Connection Parameters

Follow the steps below to define required connection properties:

1. In the Service window, right-click the Database node and click New Connection.

2. In the New Connection Wizard, enter the following connection properties:

   • Driver Name: In the menu, select the CData JDBC Driver for DB2.
   • User Name: Enter the username. This can also be defined in the JDBC URL.
   • Password: Enter the password. This can also be defined in the JDBC URL.

   • JDBC URL: Specify the JDBC URL.

     Set the following properties to connect to DB2:

     • Server: Set this to the name of the server running DB2.
     • Port: Set this to the port the DB2 server is listening on.
     • Database: Set this to the name of the DB2 database.
     • User: Set this to the username of a user allowed to access the database.
     • Password: Set this to the password of a user allowed to access the database.

     You will also need to install the corresponding DB2 driver:

     • Windows: Install the IBM Data Server Provider for .NET.

       On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

     • Java: Install the IBM Data Server Driver for JDBC.

       In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

     Built-in Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the DB2 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     java -jar cdata.jdbc.db2.jar
     

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

     A typical JDBC URL is the following:

     jdbc:db2:Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;

Query DB2 Data

To connect to DB2 data, right-click the connection in the Database node and click Connect. After the connection is established, you can expand it to discover schema information.

To load a table in the Data Views window, right-click the table and then click View Data. You can also insert, update, or delete records in the Data Views window.
