Sometimes it is useful to know the details of the WebDrillDown control being used in your JSP page. This is especially true when you have multiple versions of the control on your machine. To help you determine which version is being loaded in your application, we created a diagnostic page that loads the control in the background and displays information about the control being bound to the page.

To run this test page, unzip and place this file into your web application's root folder. Then, view the pages through your web browser. The details of the control being used will be displayed in the text box at the top of the page.

When running a control in your production environment, it is a good practice to make sure the control is properly licensed. This can be determined by looking for the phrase "Licensed" in the About property displayed on the diagnostic page. The four possible states displayed and their meaning are:

• "Evaluation" - evaluation control under 30 days of usage.

• "Expired" - evaluation control over 30 days of usage.

• "No License" - licensed control with no registration key installed.

• "Licensed" - licensed control with registration key installed.

It is important to understand that the evaluation control will not accept your registration key, and it will expire. Only the licensed control obtained from the licensed download of the product will accept your registration key and should be used in production environments.
