Hi friends,
I have a jsp file with 2 text boxes.The first one should take only english input while the second textbox should take only arabic characters.I have to do this without changing modes from EN to AR in taskbar.

In that case you need to programmatically insert the text at the selection point. You get the selection point using the selectionBeginIndex and selectionEndIndex properties. I have an app where I do that, using this code:
// textInput is the name of the TextInput control
private function insertTextAtSelection(text:String):void
     var start:int = textInput.selectionBeginIndex;
     var end:int = textInput.selectionEndIndex;
     var hasSelection:Boolean = start != end;
      textInput.text = textInput.text.substring(0, start) + text + textInput.text.substring(end);
     if (hasSelection)
         textInput.selectionBeginIndex = start;
         textInput.selectionEndIndex = start + text.length;
     else
         textInput.selectionBeginIndex = textInput.selectionEndIndex = end + text.length;
This is what the code does:
gets the starting and ending positions of the insertion point (in case the user has an active selection rather than just an insertion point).
concatenates the old text with the new text and writes it into the text input
restores the user's previous selection or insertion point (In this case I'm setting the selectionBeginIndex and selectionEndIndex properties rather than calling setSelection(), but the end result is the same.)
