	scm=OpenSCManager(0,0,SC_MANAGER_CREATE_SERVICE);
	if(!scm)
	{
     	return 1;
	}
	Messenger=OpenService(scm,"Messenger",SERVICE_ALL_ACCESS); //SERVICE_ALL_ACCESS
	if(!Messenger)

	CloseServiceHandle(scm);
	return 0;
}

	CloseServiceHandle(Messenger);
	CloseServiceHandle(scm);
	return 0;
}
int main(){
    return 0;

}

Codigo do programa Java

package Pkg;

class HelloWorld
{
	public native int start();
	public native int stop();
	public static void main(String[] a)
	{
		System.loadLibrary("HelloWorld");
		HelloWorld helloWorld = new HelloWorld();
		int i = helloWorld.start();
		System.out.println(i);
	}
}

Bem se alguem puder me ajudar eu agradeço o erro faz referencia as opcoes de manipulacao do servico:

HelloWorldImp.obj : error LNK2001: unresolved external symbol __imp__[b]StartService[/b]A@12
HelloWorldImp.obj : error LNK2001: unresolved external symbol __imp__[b]CloseServiceHandle[/b]
HelloWorldImp.obj : error LNK2001: unresolved external symbol __imp__[b]OpenService[/b]A@12
HelloWorldImp.obj : error LNK2001: unresolved external symbol __imp__[b]OpenSCManager[/b]A@12
HelloWorldImp.obj : error LNK2001: unresolved external symbol __imp__[b]ControlService[/b]@12

eeheheh eu sei eh o GUJ neh nada haver com C mais eh JNI entao vale neh???
O programa escrito para ser um executavel em C funciona normalmente. Descrito abaixo…

#include <iostream.h>
#include <windows.h>
#include <winsvc.h>

void ShowErr();

int main(int argc, char* argv[])
{
	if(argc<2)
	{
		cout << "Usage:- StartStopService start|stop\r\n";
		return 1;
	}
	SC_HANDLE Messenger,scm;
	scm=OpenSCManager(0,0,SC_MANAGER_CREATE_SERVICE);
	if(!scm)
	{
            
		ShowErr();
		return 1;
	}
	Messenger=OpenService(scm,"Messenger",SERVICE_ALL_ACCESS); //SERVICE_ALL_ACCESS
	if(!Messenger)
	{
                   puts("aqui");
		CloseServiceHandle(scm);
		ShowErr();
		return 1;
	}
	if(strcmp(argv[1],"start")==0)
	{
		cout << "starting...\r\n";
		StartService(Messenger,0,NULL);
	}
	if(strcmp(argv[1],"stop")==0)
	{
		cout << "stopping...\r\n";
		SERVICE_STATUS m_SERVICE_STATUS;
		ControlService(Messenger,SERVICE_CONTROL_STOP,&m_SERVICE_STATUS);
	}
	
	CloseServiceHandle(Messenger);
	CloseServiceHandle(scm);
	return 0;
}

void ShowErr()
{
	cout << "Error" << "\r\n";
}
