Perforce JViews Diagrammer Code Example: JDBC Data Connection

Description

This example shows how to display data contained in a database using a diagram component.

How to Use the Code Example

• Run the demo, and see the data from the two CSV files displayed in a diagram component.
• Exit the demo.
• Modify the data in CsvNodes.csv or CsvLinks.csv (for example, change a name).
• Restart the demo, and see the changes.

How to Run the Code Example as an Application

This code example can be run as an application. The installation directory contains an executable JAR file, diagrammer-jdbc.jar, that allows you to execute the code example with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the code example application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Perforce JViews.

Then, go to the installation directory of the code example and type:

ant run
