First I'll answer the question why you are getting index1.jsp as view. It will show you the view of index1.jsp when you run the application, why because you have specified index1.jsp in your welcome file list in web.xml. You will not be able to get Redirect.jsp, because you did not configure a view resolver in your SpringApp-servlet.xml. Add following bean to your SpringApp-servlet.xml

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
   <property name="prefix" value="/WEB-INF/jsp/"/>
   <property name="suffix" value=".jsp"/>
</bean>

In prefix property you have to give the path where your Redirect.jsp file is located (I am assuming in /WEB-INF/jsp folder). In suffix property you have to specify the extension of the view to be resolved.

Change the statement

return new ModelAndView("Redirect.jsp");

to 

return new ModelAndView("Redirect");

Run your application and access your application with request /Redirect.htm

It should work now. Hope this helps.

Be sure to read the spring reference manual at http://static.springsource.org/spring/docs/2.5.x/reference/view.html
