Custom JSP Tag which include another JSP

Question

I want to create a custom JSP tag as follows.

<ng:template src="../js/Rule/templates/rule-list.jsp" />

Which will actually include the file "../js/Rule/templates/rule-list.jsp" inside a scripts tag and generate HTML as follows.

<script type="text/ng-template" id="../js/Rule/templates/rule-list.jsp">
    Content of ../js/Rule/templates/rule-list.jsp file
</script>

So far I have creates following tagfile.

<%@ attribute name="src" required="true" rtexprvalue="true" %>
<script type="text/ng-template" id="${src}">
    <%@ include file="${src}" %>
</script>

Which is giving this error

File "${src}" not found

Means its trying to include the ${src} instated of its value. Can any one suggest how to include file in tag file from specified attribute value?

Note: I am using angularjs. I want to load angularjs templates without ajax call. Because my browser is not able to load ng-template with AJAX call for cross domain call problem.

Answer 1

Got it. I need to use dynamic include as

<jsp:include page="${src}" />

This is working fine.

WEB-INF directory is a special directory that is not part of the public directory tree of your web (Servlet) application.

The Servlet Specification states (page 70 or so):

A special directory exists within the application hierarchy named “WEB-INF”. This directory contains all things related to the application that aren’t in the document root of the application. The WEB-INF node is not part of the public document tree of the application. No file contained in the WEB-INF directory may be served directly to a client by the container. However, the contents of the WEB-INF directory are visible to servlet code using the getResource and getResourceAsStream method calls on the ServletContext, and may be exposed using the RequestDispatcher calls.

AngularJS cannot see any folder inside your web application WEB-INF folder since it has no "connection" to it.

You will have to add those template files in a public folder, view-able by your Angular template files.
