<%-- WEB-INF/tags/body.tag --%>
<%@ tag body-content="tagdependent" %>
Start <jsp:doBody /> End
<%-- output.jsp --%>
<%@ taglib prefix="ayo" tagdir="/WEB-INF/tags" %>
<% request.setAttribute("position","Middle"); %>
<html><body><ayo:body><%= request.getAttribute("position") %></ayo:body></body></html>
Answer:"Start End"
Reason: body-content is tagdependent, so it allows scriptlets, which is not evaluated.So no exception thrown.
------------------------------------
My question is: tagdependet treats body content as simple text. In this case, shouldn't the answer be "Start <%= request.getAttribute("position") %> End"?
<%@ tag body-content="tagdependent" %>
Start <jsp:doBody /> End
<%-- output.jsp --%>
<%@ taglib prefix="ayo" tagdir="/WEB-INF/tags" %>
<% request.setAttribute("position","Middle"); %>
<html><body><ayo:body><%= request.getAttribute("position") %></ayo:body></body></html>

On this post, you can see that you can have scriptlet inside the body of a tag file but they are ignored when you call "<jsp:doBody/>".

Correct me if I'm wrong.
