Where is the index.* files mentioned in the welcome-file tag placed ?
when the application starts, it is checking the welcome-files mentioned in web.xml inside WebContent folder . But if you have placed them inside WebContent/jsps/ the requested files wont be found. That can cause a 404.
Solutions:
1.You can move your jsps to WebContent directory.
2. In the welcome-file tag give the complete path of the index.jsp
Example : <welcome-file>/jsps/index.jsp</welcome-file>
3.Since you are using Spring and an InternalResourceViewResolver you can also configure a controller to load the welcome page instead of moving the files.
Example :
#RequestMapping(value="Login.jsp")
public ModelAndView showLoginPage(HttpServletRequest request, HttpServletResponse response ){
return new ModelAndView("Login");
}
then accessing the page using the url:
http://localhost:port/context_root_of_your_application/Login.jsp
Dispatcher Servlet will pick this call -- redirect to controller -- look for the view ("Login" ) inside /jsps/ and if matching jsp is found it will redirect to that jsp.
Hope this helps

but .js file is not linked up, please give me a directions, thanks in advance!!!
I think you should put ${pageContext.servletContext.contextPath} and you should notice the name (and version ) declare in Spring-dispatcher-servlet.xml must same with the file in /js directory (jquery-1.6.2.js,jquery-1.11.1.js, jquery.js v.v...)
<script type="text/javascript" src="${pageContext.servletContext.contextPath}/js/jquery-1.6.2.js"></script>
and as everyone suggest, make sure you have
<mvc:resources mapping="/js/**" location="/js/" />
in Spring-dispatcher-servlet.xml
hope it work
Its not a very much spring way, but I could link a javascript file as below
<script type="text/javascript" src="/js/jquery-1.11.1.js" ></script>
Please check if it works for you also.!

Using apache velocity for view

i downloaded a sample application from RoseIndia http://www.roseindia.net/tutorial/spring/spring3/web/spring-3-mvc-hello-world.html and it works fine, but i want to use apache velocity instead of jsp. what changes should i need in the current project.
Note: I have changed the suffix value to ".vm" instead of JSP. and also view resolver to
"org.springframework.web.servlet.view.velocity.VelocityViewResolver"
i could not get the desired result, i got resource not found message.

Spring & Hibernate configuration ERROR Failed to import bean definitions from URL location

I’m trying to setup a new Spring/Hibernate/Apache 7/MySQL on Windows 7 x66, using NetBeans Development environment.
All the required Spring Framework & Hibernate JARS are already prepackaged by NetBeans.
I’m getting the following error:
SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from URL location [classpath:./WEB-INF/hibernate-context.xml]
Offending resource: ServletContext resource [/WEB-INF/applicationContext.xml];
Which indicates that my applicationContext.xml cannot find my hibernate-context.xml using the following tags :
Approach 1#
<import resource="hibernate-context.xml" />
Approach #2
<import resource="classpath:./WEB-INF/hibernate-context.xml" />
My hibernate-context.xml is actually present in “../WEB-INF/hibernate-context.xml”
So this seems to be some kind of Spring classpath issue, I set the classpath in environment variables but still getting error.
Please advise me on a clean solution.

You usually have the application-context.xml mentioned in the Web.xml.
This is the master configuration for all spring context files.
application-context.xml in turn contains separate context xml file which are imported; as you have done.
This is usually the approach taken.
If you already have a fixed number of context files and you do not see them changing you can do this:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
WEB-INF/applicationContext.xml,
classpath:hibernate-context.xml
</param-value>
</context-param>
As long as the context files are in your class path; you can just use "classpath:" and it should work fine.
