DataPA requires an environmental variable, CLASSPATH, to be set on the client machine. DataPA sets this as a system wide environmental variable so DataPA will work for any user logged on to the machine. This environmental variable is often used by other applications, and some apply this variable at a user level and do not inherit the system level variable, causing this issue.

To determine whether this is the issue, follow these steps.

  1. From the start menu, select Run
  2. In the Run window, enter cmd into the open text box and press enter.
  3. At the command line prompt, type echo %CLASSPATH% and press enter.

If your CLASSPATH does not include a reference to, follow these steps to reolve it:

  1. From the start menu select Control Panel to open the control panel.
  2. From the Control Panel, select System.
  3. Select the Advanced tab in the System window.
  4. Press the Environmental Variables button.
  5. Ensure the CLASSPATH variable at the system level contains a reference to <DataPA Install Sir>/java/
  6. If CLASSPATH is set at the user level, ensure it contains a reference to <DataPA Install Sir>/java/
