Executing an file.exe from a jar file?

Question

Does anyone know how to execute an *.exe file from jar file?
I have two files that I want to execute in one java.class, Monview.exe and Moninit.exe. Both are stored in the same jar file as the class called link.class.
This is my code to run one of the files from the hard drive
String []cmd={"c:\\monview.exe"};
try
Process pr = Runtime.getRuntime().exec(cmd);
StringBuffer buf = new StringBuffer();
InputStream istr = pr.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(istr));
String str;
while ((str = br.readLine()) != null) {      
                         buf.append(str);
try {       
pr.waitFor();
} catch (InterruptedException e) { }
     if (pr.exitValue() != 0) {      
     br.close();
catch (IOException e){}
It works when i place both .exe on the local host harddrive but when I place it in the jar file nothing happens. Could anyone help me please on why does this happen and how I can fix it? Or on how to get the link.class code to extract it from the jar file and place it on the system directory and delete it from the system directory, without it knowing where the jar file comes from?

Hello,
If I am not mistaken, by including the JAR file in the CLASSPATH (specifying the absolute path), or after the -classpath option after the java command (java -classpath jar_archive main_class), the system will find both files in the JAR archive.
Hope this helps!
