The
<jsp:include>
Standard Action
The
<jsp:include>
action provides a mechanism for including additional static and dynamic
resources in the current JSP page. The syntax for this action is as follows:
<jsp:include page=”urlSpec” flush=”true” />
and
<jsp:include page=”urlSpec” flush=”true”>
<jsp:param ... />
</jsp:include>
The first syntax description does a request-time inclusion, whereas the second contains a list of
param
sub-elements that are used to argument the request for the purpose of inclusion. Table
16.6 contains the attributes and their descriptions for the
<jsp:include>
action.

This attribute represents a mandatory Boolean value stating whether or not the
buffer should be flushed. Currently, true is the only valid value for this attribute.

To further explain how the
<jsp:include>
works, we will create two JSPs. The first, which will
be the included JSP, will act as the header of the second JSP document. This JSP will search the
request
for an employee's name and title. Listing 16.3 contains the source for your first JSP.
