JavaServer Pages, Second Edition

Name

<jsp:forward>

Synopsis

The <jsp:forward> action passes the request processing control to another JSP page or servlet in the same web application. The execution of the current page is terminated, giving the target resource full control over the request.

If any response content has been buffered when the <jsp:forward> action is executed, the buffer is cleared first. If the response has already been committed (i.e., partly sent to the browser), the forwarding fails with an IllegalStateException.

The URI path information available through the implicit request object is adjusted to reflect the URI path information for the target resource. All other request information is left untouched, so the target resource has access to all the original parameters and headers passed with the request. Additional parameters can be passed to the target resource through <jsp:param> elements in the <jsp:forward> element’s body.

Syntax 1: Without parameters

<jsp:forward page="pageOrContextRelativePath" />

Syntax 2: With nested <jsp:param> actions

<jsp:forward page="pageOrContextRelativePath" />
  One or more <jsp:param> actions
</jsp:forward>
