<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" >

<property name="prefix">

<value>/WEB-INF/html/</value>

</property>

<property name="suffix">

<value>.jsp</value>

</property>

</bean>

<bean id="portletModeHandlerMapping" class="org.springframework.web.portlet.handler.PortletModeHandlerMapping">

<property name="portletModeMap">

<map>

<entry key="view"><ref local="springController"/></entry>

</map>

</property>

</bean>

<bean id="springController" class="com.sigma.SigmaController" >

<property name="viewName" value="view" />

</bean>

</beans>
