Hey all.
I have a JSP page with some text fields and a form, when submitting this
form, the jsp will called a servlet to insert the text field's values into
a database.
inside this servlet , I have a method called createUser(....) , this method
is called within doPost method.
now, should I declare createUser( ) method with the synchronized keyword
to prevent the concurrent requests ?
thanks.

I would think that any shared resource which should not have simultaneous access should be synchronized.

In your case, if this servlet can be accessed by n no. of users to create new users at the same time, then you should synchronize database access.

I would assume though that there would database row level loking while inserting...
