如何读取 JSP 到 java servlet 中的值

Question

the questions is How can i use id from servlet for use in delete submit(delete submit dont have a id input text when execute always errors 500 cause in delete cant see id )

Answer 1

What I did when I was working with jsp and servlets is passing a hidden id inside the form.

<input type="hidden" name="employeeId" value="// write value here//" />

With this you'll be able to recover it with request.getParam...
