Hai,
I have a page with couple of form fields in it.I do client side 
validations using java script and display the error message using Alert 
message. I also do some validations on the server side depending upon the 
filled in form values.

My problem is after the validation in the server side, i want to 
display it on the same page which contains the form.After validation, how 
can i display the error message in the same page.

For example: when we try to register a username which already exists, we 
get a message as "User name already exists" at the top of the form.I want 
it like that.
