Java SE (Java Platform, Standard Edition)

Is there a better way to set the Java Runtime parameters -Xms etc on Windows XP other than using the control panel and the Java Applet. This process normally has to be done for each individual user id on a system and this is extremely time consuming for many individual users.

I have found that the parameters are stored in a specific configuration file under documents and Settings/Applications Data..... however the file gives a general warning not to monkey with it as it is written back by the control panel applet.

As my PC configuration is well controlled I dont see any problem with creating a standard parameter file and copy it into this directory for each user, but would prefer a clearer approach, but cannot seem to find one.

Any suggestions and any concerns about using the template file idea?
