Answer 1

<form method="post" action="doSaveNews?NewsName1=<%=NewsName %>">

<%=NewsName %>

you are trying to submit the url using a variable called "NewsName" it is supposed to be a Java object because it is inside the scriptlet tag.

What you need to do is.

• Get the value of the input element in javascript.
• Write a "onSubmit" method in javascript, serialize the form & then form your url in javascript, submit the form.
