JSP Includes

It is possible -- and sometimes greatly desirable -- to nest JSPs.

There are two principle ways to do this:

Option 1: Directly include a file within another

<%@ include file="path/to/file.jsp" %>

Anything contained in this path is slapped directly in the HTML. This is useful if you have a lot of static elements repeated several times.

Option 2: Use a JSP include and pass in parameters

<jsp:include page="dogs.jsp" >
  <jsp:param name="dogName" value="${dogName}" />
  <jsp:param name="dogBreed" value="${dogBreed}" />
</jsp:include>

In this option, you can include a JSP file and pass in parameters. This is powerful if you have code that is very similar except for a few different values being passed through.

You can access the parameters within dogs.jsp by using ${param.dogName} and ${param.dogBreed}.
