Code:

private boolean executeShell(String strShellCmd) {
        try {
            procTemp=runEnv.exec(strShellCmd);

            //read the output from shell console
            BufferedReader brShellOP = new BufferedReader(
                    new InputStreamReader(procTemp.getInputStream()));
            String strShellOP = null;
            while ((strShellOP = brShellOP.readLine()) != null) {
                System.out.println(strShellOP);
            }
            brShellOP.close();

            // catch error from shell console (if any)
            BufferedReader brShellError = new BufferedReader(
                    new InputStreamReader(procTemp.getErrorStream()));
            String strShellError = null;
            while ((strShellError = brShellError.readLine()) != null) {
                System.out.println(strShellError);
            }
            brShellError.close();

            // wait for the process to finish
            try {
                intExitVal = procTemp.waitFor();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            
            
            //returns false if shell console throws error
            if(intExitVal!=0){
                return false;
            }
            return true;

        } catch (IOException ioEx) {
            System.out.println("error in executeShell().IOException");
            ioEx.printStackTrace();
            return false;
        }
    }

this is the entire method that does the execute operation.
Let me know if you require any other inputs for getting my issue solved.

PS: i'm new to this executing-unix-from-java thing.

Thanks a tonne,
Madhu.
