Problem: I have two identical pages home.jsp and contact.jsp with same structure. They differs only in body content and title. I want to create a Layout page using tiles framework and reuse the code for the two JSPs. The controller framework is yet not decided, it may be Spring MVC 3 or Struts 2.
Solution A: Calling JSP files/views directly from controller/action classes.
I write a single definition in tiles.xml like:
<definition name="baseLayout" template="/WEB-INF/jsp/layout/baseLayout.jsp">
<put-attribute name="title" value="" />
<put-attribute name="header" value="/WEB-INF/jsp/includes/header.jsp"/>
<put-attribute name="body" value="" />
</definition>
Now in baseLayout.jsp:
<html>
<head><title><tiles:insertAttribute name="title"/></title></head>
<body>
<div class="wrapper">
<div class="header"><tiles:insertAttribute name="header"/></div>
<div class="body"><tiles:insertAttribute name="body"/></div>
</div>
</body>
</html>
Now in home.jsp
<tiles:insertDefinition name="baseLayout">
<tiles:putAttribute name="title">
Title for home page
</tiles:putAttribute>
<tiles:putAttribute name="body">
Content for home page
</tiles:putAttribute>
</tiles:insertDefinition>
Similarly for contact.jsp :
<tiles:insertDefinition name="baseLayout">
<tiles:putAttribute name="title">
Title for contact page
</tiles:putAttribute>
<tiles:putAttribute name="body">
Content for contact page
</tiles:putAttribute>
</tiles:insertDefinition>
Solution B: Calling the tiles definition of different JSP files from cotrollers/action classes. This approach requires one tiles definition for each of the JSP file I would be writing. So altogether 3 tiles definitions (one is for baseLayout and other two are for home and contact).
tiles.xml :
<definition name="baseLayout" template="/WEB-INF/jsp/layout/baseLayout.jsp">
<put-attribute name="title" value="" />
<put-attribute name="header" value="/WEB-INF/jsp/includes/header.jsp"/>
<put-attribute name="body" value="" />
</definition>
<definition name="home" extends="baseLayout">
<put-attribute name="title" value="Title for home page" />
<put-attribute name="header" value="/WEB-INF/jsp/home.jsp"/>
</definition>
<definition name="contact" extends="baseLayout">
<put-attribute name="title" value="Title for contact page" />
<put-attribute name="header" value="/WEB-INF/jsp/contact.jsp"/>
</definition>
baseLayout.jsp : Same as **Solution A**
home.jsp : Content for home page
contact.jsp : Content for contact page
I want advice on which one of the above approaches I should stick to.

The second solution is the best way:
tiles properties for each
jsp layout.strutsFirst solution:

Solution B is the best approach to implement,
you will have individual style template what you can reuse later if required for other jsp's without messing the code in jsp like Solution A.
As of understanding the second approach is more clear and a common standard to follow.
