File.exists() returning false eventhough in reality the file exists

Question

Hi,
I am trying to create a PDF file using FDFMerge software.
For creating the PDF file, I need to execute a shell script from command-line, which I am doing using "Runtime.exec".
( I opted for this 'RunTime.exec' approach so as to read the output generated by the shell script.)
After executing the shell script and reading all the output generated by the process, I am trying to check if the PDF file exists in the location the process created.
When I do File.exists() its returning me "false" eventhough in reality the file exists.
Any guess, why this is happening?
Thanks in advance.

-SudheerI know the following method works for checking if a file exists...
public LineCounterB1()
          super( "GUI File reader" );
          tField = new JTextField("c:..\\FileScanner\\source\\test\\LineCounterB1.java");
          tField.setBackground(backColor1);
          tField.setForeground(foreColor1);
          tField.addActionListener( this );
public void actionPerformed( ActionEvent ae )
          File name = new File( ae.getActionCommand() );
          if( name.exists() )
               oArea.setText("FOUND " + name.getName() + "\n" +
                    (name.isFile() ? "File\n" : "Not a File\n" ) +
                    (name.isDirectory() ? "Directory\n" : "Not a Directory\n" ) +
                    (name.isAbsolute() ? "Absolute path\n" : "Not Absolute path\n" ) +
                    "Last modified" + name.lastModified() );
               if( name.isFile() )
                    try
                         BufferedReader reader = new BufferedReader( new FileReader( name ) );
                         StringBuffer buffer = new StringBuffer();
                         String text = null;
                         oArea.append("\n\n");
                         while((text = reader.readLine())!=null)
                              buffer.append(text + lineSep);
                         oArea.append(buffer.toString());
                    catch( IOException ioE)
                         JOptionPane.showMessageDialog(null,"Oooooo...");
                    //S7 scanner7 = new S7(/**name**/);                                        
               else if( name.isDirectory())
                    String directory[] = name.list();
                    oArea.append("\n\nDir contents:\n");                    
                         for( int i=0; i<directory.length; i++)
                              oArea.append( directory[i] + "\n");
          else
               JOptionPane.showMessageDialog(null, "No such file or directory.");
