You could try and add an  Controller annotation on top of your myController Class and try the following url   lt webappname gt  my hello html  This is because org springframework web servlet mvc support ControllerClassNameHandlerMapping prepends  my to each RequestMapping in the myController class

Had the exact same error and it took me a long time trying to understand it  It is most likely down to compilation errors  the java classes did not get published in your servlet  Please check this by going in the server that you are using  tmp1 wtpwebapps PROJECT NAME  WEB-INF classes  and try to find you controller classes to see whether or not they have been published  If not you need to get to the bottom of any compilation errors

It is not finding the controllers  this is basic issues  it can be due to following reasons   A  inside WEB-INF folder you have file web xml that refers to dispatcherServlet  Here it this case is mvc-config xml   lt servlet gt       lt servlet-name gt dispatcherServlet lt  servlet-name gt       lt servlet-class gt org springframework web servlet DispatcherServlet lt  servlet-class gt       lt init-param gt           lt param-name gt contextConfigLocation lt  param-name gt           lt param-value gt  WEB-INF mvc-config xml lt  param-value gt       lt  init-param gt       lt load-on-startup gt 1 lt  load-on-startup gt   lt  servlet gt    B  This mvc-config xml file have namespaces and it has to scan the controllers    lt context component-scan base-package  org vimal spring controllers    gt   lt mvc annotation-driven   gt    C   Check for the correctness of the package name where you have the controllers  It should work    All Controllers must be Annotated with  Controller

If you are using maven as build tool for project   build your project properly your changes in the code and xml files are not reflecting after compilations

User · Answer

If you are using   lt mvc annotation-driven  gt     make sure your spring-servlet xml has correct   lt context component-scan base-package  com     controller    gt  tag     Basically  you need to include all the packages where you have used the annotation in your java code   Also  please ensure you do not have duplication of component-scan  for a discovery of beans   If your config XML already contains the element  then any of your Controller classes that are annotated with  ComponentScan basePackages     needs to be stripped of the said annotation

I had the same issue and after lots of reserach I found the classes were not getting published in my target folder  So I had run the below two commands from cmd   mvn clean install mvn package   Surprisingly I was able to access the page and error was gone  Same can be verified from target folder where you will be able to find the complied classes which were missing earlier

Please check your  PROJECT NAME  target classes directory to see whether myController class is generated or not   If not  please check all your java source code whether there are any compilation errors

if you are using maven then do run maven install command before you run your web app on a server as it will generate a class file for your controller and in my experience that is what your application has been missing
