I have my tiles.xml as:
<tiles-definitions>
<definition name="base.definition" template="/WEB-INF/views/home.jsp">
<put-attribute name="body" value="/WEB-INF/views/menu.jsp" />
</definition>
</tiles-definitions>
And finally my servlet-context.xml has following entries:
<beans:bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<beans:property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView"/>
</beans:bean>
<!--
<beans:bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<beans:property name="viewClass">
<beans:value>
org.springframework.web.servlet.view.tiles2.TilesView
</beans:value>
</beans:property>
</beans:bean>
-->
<beans:bean id="tilesConfigurer"
class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
<beans:property name="definitions">
<beans:list>
<beans:value>/WEB-INF/tiles.xml</beans:value>
</beans:list>
</beans:property>
</beans:bean>
There is some commented part because I tried this answer from previously posted question but same problem occurred.
My POM.xml has following entries.(Just to be sure)
<dependency>
<groupId>org.apache.tiles</groupId>
<artifactId>tiles-core</artifactId>
<version>2.2.2</version>
<type>jar</type>
<scope>compile</scope>
</dependency>

<artifactId>tiles-servlet</artifactId>

I have this code in my home.jsp as:
<tiles:insertAttribute name="body" />
And my menu.jsp is:
<ul>
<li><a href="search.htm">Search</a></li>
<li><a href="showMessages.htm">Messages</a></li>
<li><a href="contacts.htm">My Contacts</a></li>
<li><a href="change.htm">Password</a></li>
<li><a href="logout.htm">Logout</a></li>
</ul>
Please help. If anything else is needed, please ask. thanks in advance.

I found the answer after few changes in the tiles.xml
The main problem with it is that you can not use the definition directly. You have to extend it and then you can use it.
Refer this my edited code:
<definition name="new.definition" template="/WEB-INF/layout/newlayout.jsp">
<put-attribute name="title" value="" />
<put-attribute name="body" value="" />
<put-attribute name="menu" value="" />
</definition>
<definition name="choice" extends="new.definition">
<put-attribute name="title" value="" />
<put-attribute name="body" value="/WEB-INF/views/choice.jsp" />
<put-attribute name="menu" value="" />
<put-attribute name="right" value="" />
</definition>
<definition name="logout" extends="new.definition">
<put-attribute name="title" value="Logging out.." />
<put-attribute name="body" value="/WEB-INF/views/logout.jsp" />
<put-attribute name="menu" value="" />
<put-attribute name="right" value="" />
</definition>
As you can see, I initially created new definition as "new.definition" and then for choice and logout I am extending the existing definition.
