You received HTTP 404 because your dispatcher controller can't find you view.
Your view is under lib folder, which is under WEB-INF folder.
All you need to do is the reconfigure you view resolver, instead of what you wrote:
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name="prefix">
<value>/WEB-INF/</value>
</property>
<property name="suffix">
<value>.jsp</value>
</property>
</bean>
write it like this: configure your view resolver to extract views from lib folder
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/lib/" />
<property name="suffix" value=".jsp" />
</bean>
One more thing, I would recommend that you place your jsp files under views folder under WEB-INF and not under lib folder.
lib under WEB-INF is a folder dedicated to 3rd party libraries and jars.
