I got it to work with a shell script.  Here are my Java source and shell
script.  Be sure the script has executable permissions.


import java.io.*;
public class execTest {
	public static void main(String argv[]) {
		//String myString[] = {"CC", "-o", "/home/escambia/jmcla/src/crypt_test", "/home/escambia/jmcla/src/crypt_test.C"};
		String myString[] = {"/home/escambia/jmcla/testscript"};
		try {
			Process rt = Runtime.getRuntime().exec(myString);
		}
		catch (IOException ie1) {
			System.out.println("Oops!");
		}
	}
}


#!/bin/csh -f

CC -o /home/escambia/jmcla/src/crypt_test /home/escambia/jmcla/src/crypt_test.C

This worked great.  Hope this helps.
