I am having some classes and an exe file in a directory. I have made them in to a Jar file. In a class file which is in that jar file i want to execute a Exe file which is also resides in that jar file. Is it possible to exexute that EXE file?
For Example....
1. Im having a directory named CLIENT.
2. In that directory I have 10 clss files and an EXE file.
3. These class files and EXE files are ziped in to a Jar file.
4. I have to give the Jar file to my client.
5. He can put that Jar file where ever he installed my product may be C driver or D drive like that
Now the problem is...
I want to execute the Exe File from one of the class where both the exe file and class file resides in the Jar file
This is my requirment
Can anyone Help to me to solve this problem?
Thanks in Advancd

Answer 1

The answer is to extract the EXE into a temp directory, execute it, and delete it when you're done. For example:
//This is the path *inside* the JAR file!
InputStream in = getClass().getResourceAsStream("/resources/myprog.exe");
OutputStream out = new FileOutputStream("myprog.exe");
File file = new File("myprog.exe");
int data;
while((data = in.read()) >= 0) out.write(data);
in.close();
out.close();
//Execute the EXE here using java.lang.Runtime.exec()
if(file.exists()) file.delete();
