Thanks for your reply :)
I have already debugged the input string s. As I said
before, s is a string which is sent by client through
the "doPost()" method of servlet
At first, I thought that the analyzer is the cause of
the problem and that it lowercase all leters. However,
then, I have also known that WhitespaceAnalyzer do
not do that.
Therefore, I changed my mind and I wonder if the
problem is resulted from the servlet technology. Yet,
when I debugged the input string s I saw that before
the method, string s was still indentical to what was
sent from client.
