Not working when file is imported

[System_Error]

Ok. In my the text editor I have been working on, I have methods that select or find parts of text. This works fine, but when you open a file, it doesn't.

Here is the code to open a file:

 public void processOpen()
 {
	 /* process Opening a new file
	 */
	 returnVal = chooser.showOpenDialog(this);
	 getFile = chooser.getSelectedFile().getPath();
	 try {
		 textArea2.read(new FileReader(getFile),null);
	 }
	 catch(IOException e)
	 {
		 e.printStackTrace();
	 }
	
	 
 }

Here is the code for finding text:

  public void processFind()
 {
	 /*  When the find method is invoked show an input dialg
	  * process the string inputed and highlight the text
	 */
	String searchString = JOptionPane.showInputDialog("Enter the string to search for");
	if (getFile == null)
	{
		String val = textArea2.getText();
		int left = val.indexOf(searchString);
		int right = left + searchString.length();
		/*  Use the setSelectionStar() and setSelectionEnd()
		*  methods to highlight the text
		*/
		textArea2.setSelectionStart(left);
		textArea2.setSelectionEnd(right);
	}
	else if (getFile != null)
	{
	}
	else 
	{
	}
 }

And here is the code to select all:

 public void processSelectAll()
 {
	 /*  When Select all is clicked by the user
	  *  process the starting and ending of the 
	  *  text area and select all of it
	  */
	 String val = textArea2.getText();
	 int left = val.indexOf(val);
	 int right = left + val.length();
	 /*  select it
	  */
	 textArea2.setSelectionStart(left);
	 textArea2.setSelectionEnd(right);

 }

I don't know why there would be conflict when I set the contents of the file to the text area.
Can anyone help me with this?
