using namespace std;
int main()
{
 while(true)
 { 
  system("ps auwx | grep \"java -jar BusinessServer.jar\" | grep -v \"grep\" > MonitorServer.log");
  sleep(1);
  FILE* pFile = fopen("/usr/myprogram/MonitorServer.log","r");
  char result[512] = "\0";
  if(pFile != NULL)
  {
   fscanf(pFile,"%s",result);
   fclose(pFile);
  }
  if(strcmp(result,"\0") != 0)
  {
   cout<<"BusinessServer.jar is alive"<<endl;  
  }
  else
  {
            system("java -jar BusinessServer.jar &");
   cout<<"BusinessServer.jar is dead"<<endl;
