These notes illustrate an interesting way of developing and using capture tags in jsp to accomodate masterpages or tiles. This specific example talks about how this is done in AspireWeb but the ideas can be easily extended to any java based server side framework.
The notes will explore a) how to define a jsp page in response to an incoming url in an MVC fashion b) it then goes into identifying a tiles or masterpage pertaining to that URL c) an example of the master page d) an example of the jsp page with capture tags e) the resulting out put combining the master page and the url specific jsp page. f) what the incoming url will look like

Define your primary content page
captestJSPURL=/testdir/capture/capture-test1.jsp
captestJSPURL.transformType=JSP
request.captestJSPURL.transform.className=com.ai.jsp.JSPTransform
captestJSPURL.dataRequestName=mydata
request.mydata.className=com.ai.htmlgen.DBHashTableFormHandler1

Define your master page
#############################################
# Your master jsp page
#############################################
captestURL=aspire:\\testdir\\capture\\captest.html

The master page looks like: captest.html
<html>
<head>
<title>A custom tag: body content</title>
</head>
<body>
<hr>
{{cap1}}
<hr>
<p>After
</body>
</html>

the content jsp looks like:capture-test1.jsp
<%@ taglib uri="/aic" prefix="aic" %>
<%@ page import="com.ai.htmlgen.*" %>
<%@ page import="com.ai.application.utils.*" %>
<%@ page import="com.ai.common.*" %>
<%@ page import="com.ai.aspire.utils.*" %>
<%!
String hello()
{
return "helloworld. in deed";
}
%>
<%
ihds pageData = (ihds)request.getAttribute("Aspire.formHandler");
if (pageData == null)
{
out.println("Some html segment about empty data set if needed");
return;
}
%>
<aic:CaptureTag captureAsName="cap1">
<p>Hello world</p>
<p>
<%="My name is super"%> <%=hello()%>

<%
String cap1Value = (String)request.getAttribute("cap1");
java.util.HashMap map = new java.util.HashMap();
map.put("cap1",cap1Value);
java.io.PrintWriter myout = new java.io.PrintWriter(out);
TransformUtils.transformHds("captestUrl",myout,(IFormHandler)pageData,map);
%>
