Problem with opening a file in its application using Runtime

Question

Dear experts,
excuse me for my ignorance, but I am facing a problem and I would really
appreciate some help. I am working on a java program in which I want the user
to have the ability to save the contents of a JTable into a file of his preference (the file could be of any type i.e xls, txt, doc...) and then open this file in its
default application (i.e the txt file through notepad, the xls file through excel etc..).
Everything works fine with the code below, if the filePath does not contain blank spaces. I did some search on the forun and the web, and also tried to
find a solution through the great link
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html but I still
cannot solve the problem. Below I quote the part of the code (actually the actionPerformed dunction of the equivallent button) which is responsible for the opening of the file.
    excelButton.addActionListener(new ActionListener()
       public void actionPerformed(ActionEvent e)
         //saveFileName is the File that I want to open
         String filePath = "\""+saveFileName.toString()+"\"";
         System.out.println(""+filePath);
         try
          String cmd="cmd.exe /C start "+filePath;
          String cmd="cmd.exe /C start C:\\Documents and Settings\\test.xls";
          Process p = Runtime.getRuntime().exec(cmd);
         }catch(IOException ec){}
     });Thank you in advance for your help!
Sincerely yours,
JIM
