SEVERE: Servlet.init() call for Servlet [appServlet] caused an exception

While implementing CRUD with a spring, this error occurred and has not been able to proceed with CRUD for several hours...
"Line 7 of the xml document of the servlet context resource [/web-inf/spring/appservlet/slaplet-slap.xml] is invalid."
Even if line 7 is erased, line 6 is an error and line 5 is an error if erased once again, so I don't think this is an empty tag problem.
Just in case, I'll put the controller and dao.
I'm worried that it'll be uncomfortable to watch. sorry..
help me!!

Web Application based on Spring Security crashes during startup (NullPointerException)

My application, which make use of Spring Security, is crashing during the startup. Tracking the execution of the application, I could verify the error is happening in method onStartup from class MainWebAppInitializer:
public class MainWebAppInitializer implements WebApplicationInitializer {
/**
* Register and configure all Servlet container components necessary to power the web application.
*/
#Override
public void onStartup(final ServletContext sc) throws ServletException {
// Create the 'root' Spring application context
final AnnotationConfigWebApplicationContext root = new AnnotationConfigWebApplicationContext();
root.scan("com.spring.web.config");
// Manages the lifecycle of the root application context
sc.addListener(new ContextLoaderListener(root));
// Handles requests into the application
final ServletRegistration.Dynamic appServlet = sc.addServlet("horariolivreapp", new DispatcherServlet(new GenericWebApplicationContext()));
appServlet.setLoadOnStartup(1);
final Set<String> mappingConflicts = appServlet.addMapping("/");
if (!mappingConflicts.isEmpty()) {
throw new IllegalStateException("'appServlet' could not be mapped to '/' due " + "to an existing mapping. This is a known issue under Tomcat versions " + "<= 7.0.14; see https://issues.apache.org/bugzilla/show_bug.cgi?id=51278");
}
}
}
More specificly, the error occurs in the line
appServlet.setLoadOnStartup(1)
where a NullPointerException is triggered. Follow it is my configuration files, for reference:

Looking in this files, someone can find the reason for this problem?
UPDATE 1
This is my Controller (DispatcherServlet) class:
package com.horariolivreapp.controller;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import com.horariolivreapp.core.Sessao;
import com.horariolivreapp.data.UsuarioDAO;
#Controller
public class HorarioLivreController {
private Sessao sessao;
#RequestMapping("/cadastra_evento")
public ModelAndView cadastra_evento() {
return null;
}
#RequestMapping(value="/listagem_evento", method=RequestMethod.GET)
public ModelAndView listagem_evento() {
return null;
}
#RequestMapping("/cadastra_horario")
public ModelAndView cadastra_horario() {
return null;
}
#RequestMapping("/listagem_horario")
public ModelAndView listagem_horario() {
return null;
}
#RequestMapping("/cadastra_usuario")
public ModelAndView cadastra_usuario() {
return null;
}
#RequestMapping("/listagem_usuario")
public ModelAndView listagem_usuario() {
return null;
}
#RequestMapping("/cadastra_tipo")
public ModelAndView cadastra_tipo() {
return null;
}
#RequestMapping("/cadastra_campo")

return null;
}
#RequestMapping("/usuario_config")
public ModelAndView usuario_config() {
return null;
}
#RequestMapping(value="/usuario_login", method=RequestMethod.POST)
public ModelAndView usuario_login(#RequestParam("j_username") String username, #RequestParam("j_password") String password) {
UsuarioDAO usuario = new UsuarioDAO(username, password);
if(usuario.getUsuario() != null) {
this.sessao = new Sessao(usuario.getUsuario());
}
return new ModelAndView("usuario_start","usuario",usuario.getUsuario());
}
#Configuration
#ImportResource({ "classpath:webSecurityConfig.xml" })
public class SecSecurityConfig {
public SecSecurityConfig() {
super();
}
}
}

An NPE at that point means that appServlet is null, which in turn means that sc.addServlet(...) returned null.
The Javadoc for addServlet says this:
"Returns: a ServletRegistration object that may be used to further configure the given servlet, or null if this ServletContext already contains a complete ServletRegistration for a servlet with the given servletName or if the same servlet instance has already been registered with this or another ServletContext in the same container."
Now you are instantiating the Servlet object at that point, so it cannot have previously been registered. But there could be another Servlet with the same name ... and that's the probable immediate cause of the problem.
And in fact, it looks like you have already registered a servlet called "horariolivreapp" by declaring it in the web.xml file.

How can I map my Spring URL to a JSP file in /WEB-INF/views?

I'm having trouble doing a Spring (using 3.0.5.RELEASE) mapping. I want to map the URL http://mydomain/context-path/user/registrationform.jsp to my JSP page at
/WEB-INF/views/user/registrationform.jsp
but I'm getting a 404. I have my controller setup like so …
#Controller
#RequestMapping("registrationform.jsp")
public class RegistrationController {
private static Logger LOG = Logger.getLogger(RegistrationController.class);
…
public void setRegistrationValidation(
RegistrationValidation registrationValidation) {
this.registrationValidation = registrationValidation;
}
// Display the form on the get request
#RequestMapping(method = RequestMethod.GET)
public String showRegistration(Map model) {
final Registration registration = new Registration();
model.put("registration", registration);
return "user/registrationform";
}
here is my dispatcher-servlet.xml …

What else do I need to configure (or configure differently) to make this mapping work? This is harder than - Dave

#RequestMapping("registrationform.jsp")
public class RegistrationController {
The RequestMapping annotation at class level should be use for a common url pattern like "item/*" and all the links that contains "/item" followed by other pattern would be mapped it to the controller. "user/" in your case
The RequestMapping annotation at method level is used for mapping the sub URL like "item/add" or "item/delete", "registrationform.jsp' in your case
So try this:
#Controller
#RequestMapping("/user")
public class RegistrationController {
private static Logger LOG = Logger.getLogger(RegistrationController.class);
…
public void setRegistrationValidation(
RegistrationValidation registrationValidation) {
this.registrationValidation = registrationValidation;
}
// Display the form on the get request
#RequestMapping(value="/registrationform.jsp",method = RequestMethod.GET)
public String showRegistration(Map model) {
final Registration registration = new Registration();
model.put("registration", registration);
return "user/registrationform";
}
This will map /user/registrationform.jsp

Change the RequestMapping to:
#RequestMapping("/user/registrationform.jsp")
