Hi

I am having exactly the same problem. Are functions like getParameter(),getParameterNames() deprecated?

Please help.

I think you will need the <Form> element in HTML.

<form action="" method="">
.. have your input text box here
</form>

You need to specify the form action that will handle whatever parameters you are submitting.

Try this html and I believe you already have a Servlet where the request should be submitted.
Change action attribute value of form to the actual one with the context prefixed.
