Runtime.exec does not execute my program, but executes "ls"

Question

I am trying to run an exe from a Java program.
The program that I want to run is an output of a gcc -o ICDDATA ICDdata.c
Now when I use the Runtime.exec() and execute "ls", "cat" it is working fine without any errors.
But when i try to give the file(ICDDATA) that was created with the gcc, it generates an error code of "11" or "10" and exits the process.
Could anyone please let me know the reason why this is happenig and suggest and appropiate solution for this.

Answer 1

When I give ICDDATA at the prompt, it is executing perfectly fine.
But only when it is run inside the Java program its giving the error code 10.
Here is the source code:
======================================
public class InvokeInterface {
     This method takes two parameters and accordingly invokes one of the
     interface (ICD / Value).
     @Input : String, String
     @Return : void
     static void executeInterface(String processName, String debugOption)
     throws java.io.IOException     {
          String commandToExecute=". / ";
               // The command that has to be passed to the Shell.
          if(processName.equals("ICD"))
               commandToExecute="ICDDataRefresh";
          if(processName.equals("VALUE"))
               commandToExecute="ValueDataRefersh";
          commandToExecute += " "+debugOption;
          System.out.println("..."+commandToExecute);
          Runtime runtime = Runtime.getRuntime();
          Process proc = runtime.exec(commandToExecute);
               try {
                    if (proc.waitFor() != 0) {
                    System.err.println("exit value = " +
                    proc.exitValue());
          catch (InterruptedException e) {
               System.err.println(e);
