Running jar files from the command line

Question

I have always felt it would be useful to run a jar file from th command line in EXACTLY the same way as an EXE. On some systems, typing MYAPP.JAR will run the app, but doesn't output and command line data, so it only works for GUI apps. I've come up with a tiny C program that runs java -jar xxxx.jar for you.
#include <stdio.h>
#include <string.h>
#include <process.h>
void main(int argc,char *argv[])
     char cmd[1024];
     strcpy(cmd,"java -jar ");
     strcat(cmd,argv[0]);
     strcat(cmd,".jar");
     for(int arg=1;arg<argc;arg++)
          strcat(cmd," ");
          strcat(cmd,argv[arg]);
     system(cmd);
}Simply compile this to an exe, rename the exe to the name of your jar file and put it in the same directory. Then just type 'MyJarFile' (no jar extension) and it should run. It passes all command live args as well. Comments ?

Here's a better version. The JAR and the EXE can be anywhere in the PATH:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <process.h>
void main(int argc,char *argv[])
     char jar[1024];
     char cmd[1024];
     strcpy(cmd,argv[0]);
     strcat(cmd,".jar");
     _searchenv(cmd,"PATH",jar);
     strcpy(cmd,"java -jar ");
     strcat(cmd,jar);
     for(int arg=1;arg<argc;arg++)
          strcat(cmd," ");
          strcat(cmd,argv[arg]);
     system(cmd);
}
