Just follow up on Christophe with some book-keeping:
We prefer to keep conversations in the forums rather than email. That way it helps everyone. 'abt servlet' is not a useful topic and won't help you get a response. Putting more effort in to your posts gives a better chance of a useful response.
In an effort to help you get the most from our forums, we've compiled a list of tips for asking questions here. You can find the list in our FAQ section here. In particular please see: UseAMeaningfulSubjectLine In a forum dedicated to servlets the subject line 'about servlets' is completely meaningless.
UseRealWords Abbreviations such as "u" or "ur" in place of "you" and "you are" or "you're" confound language translation software making it hard for our non-English speaking members to read your posts. 'abt' is not a word in the English language.
Again, welcome to JavaRanch and good luck with your question. -Ben
