How to set value of html text field using java code

Question

I can get the value of a textfield from html to java using the following code:

String id = request.getParameter("id");

Is there a way where I can set an HTML text field using a Java code?

Answer 1

Just let JSP/EL print it in the value attribute of the field.

<input type="text" name="id" value="${param.id}" />

or, better, to avoid XSS attacks, use JSTL fn:escapeXml().

<input type="text" name="id" value="${fn:escapeXml(param.id)}" />
