I suspect that your vector v has size zero and thus is not giving you anything in your text area.
Suggest you add a line or two of debug code to see what is being returned, if anything.



Vector v=methodCallwithReturntypeVector();
textAreaObject.append("v.size() = " + String.valueOf(v.size());
System.out.println("v.size() = " + String.valueOf(v.size());
for(int i=0;i<v.size();++i){
   System.out.println((String)v.elementAt(i));
   textAreaObject.append((String)v.elementAt(i));
}

Suggest you run the command
validate with the text area or the container object which contains the textarea.

If you are not getting anything at all to show up in the textarea, then the textarea you think you are writing to must not be the one you are looking at. This might mean that you have defined the textarea more than one time in your program, perhaps once globally and another time locally, with the global version being the one you are looking at and the local (inside a method) the one you are writing to. (OR vice versa).

You should be able to write and see the result of some fool proof dummy code you can insert to test it.

Suggest you look for where the text area is declared by searching all the times it occurs in your source code. (Control-F in windows..)
