JNA:com.sun.jna.platform.win32.Win32Exception- access denied

问题:

I use following code to control a windows service from java program

public class PostgresService2 {     public static void main(String[] args)     {         try             {                 W32ServiceManager serviceManager = new W32ServiceManager();                 serviceManager.open(Winsvc.SERVICE_STOP);                 W32Service service = serviceManager.openService("DBService",                         Winsvc.SERVICE_ACCEPT_STOP);                 service.stopService();                 service.close();              }              catch (Exception ex)              {                  ex.printStackTrace();              }     } } 

This gives error on windows7 (64bit) machine

The shell from where the command is run has administrative privileges. How I can provide full access?

回答1:

I am using SC_MANAGER_ALL_ACCESS and that works. Not sure if that helps.

 W32ServiceManager serviceManager = new W32ServiceManager();                serviceManager.open(Winsvc.SC_MANAGER_ALL_ACCESS);                W32Service service = serviceManager.openService("servicename", Winsvc.SC_MANAGER_ALL_ACCESS);
