2.13.4.1

Syntax

and

{  }*

The first syntax just does a request time inclusion.  In the second case, the values in the 

param subelements are used to augment the request for the purposes of the inclusion.

The valid attributes are:

page

The URL is a relative 

urlSpec

 is as in Section 2.5.2.

Accepts a request time attribute value (which must evaluate to a String 

that is a relative URL specification).

flush

Mandatory boolean attribute. If the value is  true , the buffer is 

flushed. A  false  value is not valid in JSP 1.1.

2.13.5

A 

 element allows the runtime dispatch of the 

current request to a static resource, a JSP pages or a Java Servlet class in the same context as 

the current page. A jsp:forward effectively terminates the execution of the current page. The 

relative 

urlSpec

 is as in Section 2.5.2.

The request object will be adjusted according to the value of the 

page

 attribute.

A 

jsp:forward

 action may have 

jsp:param

 subelements that can provide values for 

some parameters in the request to be used for the forwarding.

If the page output is buffered then the buffer is cleared prior to forwarding.

If the page output was unbuffered and anything has been written to it, an attempt to forward 

the request will result in an 

IllegalStateException

.

Examples

The following element might be used to forward to a static page based on some dynamic 

condition.

<% String whereTo =  /templates/ +someValue; %>
