}
please change your url pattern with ".so". all ".so" request are consider as spring request and handle by spring dispatcher servlet.
Your call is wrong. First there should be an app name and then request name.
You have to call like below :
localhost:8080/YourAppName/htmlPage

Please to change the order between <context:component-scan base-package="com"/> and <mvc:annotation-driven/> make <mvc:annotation-driven/> the first

I am making a dummy hello world applicatiion for Spring MVC, i have done exactly same as was mentioned in example, but when i run the URL, its giving me the 404 error. Please help me if you can, following are my files:-

public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}
Please let me know if you have any suggestions
i guess the mvc:annotation-driven element should be used in your moqahServices, check it out
Looking into your code it seems,
1) you configured mvc:default-servlet-handler in the wrong place. It should be the part of your spring configurations.
2) In web.xml considering the servlet-name as moqahServices, spring configuration name should be suffixed with -servlet.xml followed by servlet-name ie. your spring configuration name is expected as moqahServices-servlet.xml
Please Try doing above changes.

I can't view my project in this url: localhost:7001/MTSM/
and also not available in: localhost:7001/MTSM/hello.jsp
It was working 2 days ago. I think I'm deleted something in web.xml, but I don't remember.
Do you know what problem is?
I uploaded my project here: [Dropbox -- MTSM_20140112.zip][3]
Thanks.
According to the logs you provided in pastie (that's bad : you should have providen the relevant part as an edit), spring tried to load WEB-INF/pages/ss.jsp and did not find it. I means :
you probably hit the controller HelloController
the method printWelcome returned ss as a string
due to mvc-dispacher-servlet.xml, InternalResourceViewResolver looked for WEB-INF/pages/ss.jsp (normal untill here)
as the file does not exist you got a 404 error (still normal : it is not what you expected, but what you asked)
You should try to be coherent between view names returned by controller and actual jsp file :
#RequestMapping("/")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Hello world!");
return "hello";
}
}
should forward to view WEB-INF/pages/hello.jsp (that exists according to you project image)
I am new to spring and was working on the Hello world application in MVC The URL mapping is searched as a corresponding view when i return the ModelAndView object from the controller..I have included all proper jars.This is the code..

The HelloWorldController is..

The url was given as //localhost:8080/sample/welcome it gave 404 as it was trying to find welcome.jsp instead of hello.jsp

Also it looks like you have imported the portlet version of ModelAndView, make sure this is what you desire. If not import, org.springframework.web.servlet.ModelAndView
You are using wrong ModelAndView class
import org.springframework.web.portlet.ModelAndView;
it should have been
import org.springframework.web.servlet.ModelAndView;
everything else is fine.
I am receiving the message "The requested resource () is not available." when going to a url that I have mapped using DispatcherServlet. It previously worked when I had the mapping setup to use a .do extension, but when I map without an extension it doesn't work.

#Controller

If I have the mapping set to *.do and the RequestMapping set to wod.do it works fine.
EDIT:
In the logs, when I go to that URL it shows the message
No mapping found for HTTP request with URI [/foobar/json/wod] in DispatcherServlet with name 'dispatcher'
EDIT 2: I added the alwaysUseFullPath to the handler:
<bean id="annotationHandlerMapping"
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="alwaysUseFullPath" value="true" />
</bean>
This was due to the way my apache redirect was setup.
