2.13.5.1

Syntax

and

{  }*

This tag allows the page author to cause the current request processing to be effected by the 

specified attributes as follows:

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).

2.13.6

The 

jsp:param

 element is used to provide key/value information.  This element is used in 

the 

jsp:include

, 

jsp:forward

 and 

jsp:plugin

 elements.

When doing 

jsp:include

 or 

jsp:forward

, the included page or forwarded page will 

see the original request object, with the original parameters augmented with the new 

parameters, with new values taking precedence over existing values when applicable.  The 

scope of the new parameters is the jsp:include or jsp:forward call; i.e. in the case of an 

jsp:include

 the new parameters (and values) will not apply after the include. This is the 

same behavior as in the 

ServletRequest

include

 and 

forward

 methods (see Section 

8.1.1 in the Servlet 2.2 specification). 

For example, if the request has a parameter A=foo and a parameter A=bar is specified for 

forward, the forwarded request shall have A=bar,foo. Note that the new param has 

precedence.

2.13.6.1

Syntax

This action has two mandatory attributes: name and value.  Name indicates the name of the 

parameter, value, which may be a request time expression, indicates its value.
