I get the following error when trying to set up a Spring project with Velocity.
PageNotFound - No mapping found for HTTP request with URI [/SpringMVCVelocity/Enquiries/viewAllEnquiries] in DispatcherServlet with name 'mvc-dispatcher'
I have set up the spring context.xml as-

My controller is:
#Controller
#RequestMapping("/Enquiries")
#SessionAttributes({"enqList", "search"})
public class EnquiryController {
private static final Logger logger = Logger.getLogger(EnquiryController.class);
private PagedListHolder<Enquiry> enqList = null;
private int pageSize = 10;
#Autowired
private EnquiryDao enquiryDao;
#RequestMapping("/viewAllEnquiries")
public String getAllEnquiries(#RequestParam(required=false) String page, Model model) {
if ("next".equals(page) && enqList != null) {
enqList.nextPage();
} else if ("previous".equals(page) && enqList != null) {
enqList.previousPage();
} else {
// well there is no page parameter, so it must be a new request
enqList = new PagedListHolder<Enquiry>(enquiryDao.getAllEnquiries());
enqList.setPageSize(pageSize);
}
model.addAttribute("search", new Search());
model.addAttribute("enqList", enqList);
return "viewAllEnquiries";
}
This controller is not even called. It does however successfully manage to resolve the welcome view with:
<mvc:view-controller path="/" view-name="welcome"/>
Problem solved,
I wasn't scanning the controller (context:component-scan) and had not wired the bean either in the Spring context.
So to fix it, I added it via spring injection:
<bean id="enquiryDao" class="ecommerce.dao.EnquiryDao"/>
<bean id="enquiryController" class="ecommerce.controller.EnquiryController">
<property name="enquiryDao" ref="enquiryDao"/>
</bean>

Please help. The below is my XML configuration file. My application runs properly. But it says no database selected when call database.
The exception looks like below:

I will be pleased for any suggestion.
Do not configure both jdbcUrl and dataSourceClassName, pick one style or the other. In this case, I suggest you stick with jdbcUrl.
I'm using spring mvc 4 , and there is a problem with message params in validation messages.
for example the output of #Size is : size must be between min and max.
and key bundle in hibernate validator is size must be between {min} and {max}.
this is my spring mvc config :

where is the problem?
finally i figured out the problem ...
i have to set
messageSource.setUseCodeAsDefaultMessage(false);
and then all message params replaced with the correct value !

I am trying to use struts2 validations. I have a setup with Struts2.2.3 and Spring 3.0.5. I have a -validation.xml in place. Fields are getting validated and error message is getting displayed on the server console, but its not getting displayed on the UI. Also action is not getting forwarded to the results specified for the "input" tag.
My action class does not extend from ActionSupport instead it implements Preparable. Is this could be the problem?
So I also tried with my Action class define as
public class CandidateAction extends ActionSupport implements Preparable
on hitting the page i am getting following error
Invalid action class configuration that references an unknown class named [candidateAction]
even though i have a bean defined with name "candidateAction" in the application context.xml

I can't figure out why Autowired of DAOs classes works fine in Test classes but not in servlets. web.xml file load correctly context configuration as i can see by the log, so the problem must be in my applicationContext file.
This is my servlet:
#Controller
public class TestAutowired extends HttpServlet {
private static final long serialVersionUID = 1L;
#Autowired
private IUserDao uDao;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
uDao.getUserById(1);
}
}

The servlet lifecycle is managed by the container, not Spring.
