Default Ensure only one appl. is execution on PC?

Hi there,

Due to my inadequacy, I need some help for one “simple problem”.
(1) Only one copy of the application can be executed at one time on a desk top. One of the solutions I am trying is to check if a “special temporary file” existed when it first invoked. If the “file” existed, message is displayed to alter the user before it aborts itself. Conversely it creates a temporary file which will be deleted when this application is completed by the user. However this approach will cause problem when the system crashes or the user “kills” it. Under this abnormal condition, the temporary file will cause problem. Is there a method that Java provided for detecting this condition?
