Why cant I register a HttpRequestHandlerServlet via #Bean annotation in Spring Boot

I am currently using SpringBoot and a #Configuration JavaClass to register the Servlet HttpRequestHandlerService
But It always tells me that is is not available
Here is my code Class for the registration of the bean:
#Configuration
public class WebConfiguration extends SpringBootServletInitializer {
private static final String SERVLET_NAME = "DataFileServlet";
/**
* Initializer servlet context initializer.
*
* #return the servlet context initializer
*/
#Bean
public ServletContextInitializer initializer() {
return servletContext -> {
servletContext.setInitParameter("javax.faces.FACELETS_SKIP_COMMENTS", "true");
servletContext.setInitParameter("contextConfigLocation", "classpath:applicationContext.xml");
servletContext.setInitParameter("javax.faces.FACELETS_REFRESH_PERIOD", "1");
servletContext.setInitParameter("primefaces.THEME", "admin");
servletContext.setInitParameter("primefaces.FONT_AWESOME", "true");
servletContext.setInitParameter("com.sun.faces.sendPoweredByHeader", "false");
servletContext.setInitParameter("javax.faces.CLIENT_WINDOW_MODE", "url");
};
}
/**
* Is used to register the servlet HttpRequestHandler.
*
* #return the servlet "registartionBean"
*/
#Bean
public ServletRegistrationBean<HttpRequestHandlerServlet> dataFileServletRegistration() {
ServletRegistrationBean<HttpRequestHandlerServlet> registrationBean = new ServletRegistrationBean<>(new HttpRequestHandlerServlet());
registrationBean.setName(SERVLET_NAME);
registrationBean.setLoadOnStartup(1);
return registrationBean;
}
/**
* Is responcable for registering a filter.
*
* #return the filter "registrationBean"
*/
#Bean
public FilterRegistrationBean<CharacterEncodingFilter> encodingFilter() {
FilterRegistrationBean<CharacterEncodingFilter> registrationBean = new FilterRegistrationBean<>(new CharacterEncodingFilter());
registrationBean.setEnabled(true);
registrationBean.setOrder(1);
registrationBean.addInitParameter("encoding","UTF-8" );
registrationBean.addInitParameter("forceEncoding", "true");
return registrationBean;
}
/**
* Is resposible for registering a new listener.
*
* #return the listener "registrationBean"
*/
#Bean ServletListenerRegistrationBean<IntrospectorCleanupListener> IntrospectorCleanupListener(){
ServletListenerRegistrationBean<IntrospectorCleanupListener> registrationBean = new ServletListenerRegistrationBean<>();
registrationBean.setListener(new IntrospectorCleanupListener());
return registrationBean;
}
}
and here is my Stacktrace

What Can I do to get It to work properly?

HttpRequestHandlerServlet delegates to an HttpRequestHandler bean. This is described in the class's javadoc:
delegates to an HttpRequestHandler bean defined in Spring's root web application context. The target bean name must match the HttpRequestHandlerServlet servlet-name
When defining the registration bean for the servlet you have set its name to DataFileServlet. As a result, when the servlet receives a request, it is attempting to retrieve a bean named DataFileServlet. This is failing as there is no bean defined with that name.
To use HttpRequestHandlerServlet as you have configured it, you need to define an HttpRequestHandler bean named DataFileServlet:
#Bean(name="DataFileServlet")
public HttpRequestHandler dataFileServlet() {
return (request, response) -> {
// Handler implementation
};
}

You are importing #Import({SecurityConfig.class}) however in your project the class which extends WebSecurityConfigurerAdapter is SecurityConfiguration.
So try changing the line:
#Import({SecurityConfig.class})
to:
#Import({SecurityConfiguration.class})

I had this same exception, and it turns out that my AbstractAnnotationConfigDispatcherServletInitializer#getRootConfigClasses
was returning an array containing an instance of org.springframework.security.access.SecurityConfig rather than my own implementation of WebSecurityConfigurerAdapter which also happened to be named SecurityConfig. The org.springframework.security.access.SecurityConfig constructor takes a single string argument, which is where the unsatisfied dependency autowiring error is coming from.
If you are using a class named SecurityConfig make you imports are pulling from the correct packages, as your IDE's "auto import" feature can get you into trouble on this one as

}
}

Error was because dispatcher Servlet file. The Correct way of declare entitymanagerfactory was different. DatabaseInitilizer Class is used to intialize the database username and password in a encrypted format.

Where is passwordEncoder being constructed and set in the DataBaseInitializer? It looks like its still null when initDataBase() is called here:
User userUser = new User("user", this.passwordEncoder.encode("user"));

I have seen similar questions on SO, but none related to java/lang/Object.class. I hae no idea what is causing this.

Here is my WebConfig class:
#EnableWebMvc
#Configuration
#ComponentScan(basePackages = {"com.jverstry", "org.krams"})
#ImportResource("WEB-INF/spring-security.xml")
public class WebConfig extends WebMvcConfigurerAdapter {
#Bean
public ViewResolver getViewResolver() {
InternalResourceViewResolver resolver
= new InternalResourceViewResolver();
resolver.setPrefix("WEB-INF/pages/");
resolver.setSuffix(".jsp");
return resolver;
}
}

That is most peculiar.
Lets start with the what we do know. The class java.lang.Object and the corresponding java/lang/Object.class file most certainly do exist. If they didn't then is is highly unlikely that the JVM would have started in the first place.
So how come you get the exception?
My theory it that somewhere in your codebase (or the libraries you are using) there is a classloader that is breaking the rules. When it is asked to load a resource, a well behaved class loader will first delegate up the class loader chain to see if its parent classloader can load the resource. I suspect that what is happening is that the broken classloader is skipping the delegation step and just trying to load the resource itself. If the "rt.jar" is not on its list of JARs, etc (and it normally won't be) then the class loader won't find the Object.class file ... and you will get a FileNotFoundException.
UPDATE
I think I understand. If your Java installation was corrupted to the extent that it couldn't load java.lang.Object, then the JVM wouldn't boot. And if it had already booted before the corruption, then it wouldn't be trying to load the Object class.
But it is not trying to do that. It is actually trying to read the Object.class file. And the stacktrace seem to be saying that this is occurring in Spring's annotation processing code.
So I think that something has triggered a servlet restart after the Java installation was compromised. And the restart caused the spring configuration to be done again. Why it worked when you rebooted is a mystery ... unless the problem was due to a hardware error or stuck device driver that was cleared by the reboot.
(The post you found describes a different scenario ... where the JVM fail during its bootstrap. Your scenario is more complicated.)

It turns out my JRE6 installation was somehow corrupted. I reinstalled it manually and now I don't have an issue anymore. I have also found another post which might explain why the issue would disappear after rebooting.

Mapping URL to Java methods using Google App Engine and Jersey

I am trying to run the HelloWorld example for Jersey, but failing. This is what I've tried.
I have setup my appengine-web.xml like this

I have my service setup like this,
package com;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
#Path("/helloworld")
public class service {
#GET
#Produces("text/plain")
private String getString(){
return "hello";
}
}
I am using these libs
asm-3.3.1.jar
jersey-bundle-1.12.jar
jersey-core-1.12.jar
jersey-server-1.12.jar
Here's a video of the issue http://screencast.com/t/oIYKMQw1x
Any idea's what I'm doing wrong?
Thanks!

So my issue was that I was mapping to com.service which is the class. I needed to map to the package containing my class.
