Hi All,
I am trying to migrate an application using Sprig 2.5.0 and Tiles 2 under Websphere 6.1 which gives me the below exception .Kindly note the same web application works fine under Tomcat 5.5 container.

Any help to resolve this issue would be greatly appreciated.

ApplicationContext.xml contains

<!-- Tiles Configuration -->
<bean id="tilesConfigurer"
class="org.springframework.web.servlet.view.tiles2 .TilesConfigurer">
<property name="definitions"
value="/WEB-INF/tiles/tiles-def.xml" />
</bean>

<bean id="viewResolverTiles"
class="org.springframework.web.servlet.view.UrlBas edViewResolver">
<property name="order" value="2" />
<property name="viewClass"
value="org.springframework.web.servlet.view.tiles2 .TilesView" />
</bean>
