Java Spring get data from html form

We would need more configuration to Spring modules to get this working. You may go with Option 1 - with web.xml or Option 2 - without web.xml:

Option 1 (web.xml)

1. Modify your web.xml to:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">
    <display-name>SimpleProject</display-name>

    <servlet>
        <servlet-name>SimpleProjectServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>
                 /WEB-INF/config/SimpleProjectServlet-servlet.xml
            </param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>SimpleProjectServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>query.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
</web-app>

2. Create file with path - WEB-INF/config/SimpleProjectServlet-servlet.xml

3. Add following contents to the file created in Step 2. You would need to edit the Spring version references:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.2.xsd">
    <context:component-scan base-package="com.mycompany.myproject" />
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/views/jsp/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>
    <mvc:resources mapping="/resources/**" location="/resources/" />
    <mvc:annotation-driven />
</beans>

4. Set right package name as you have in the above configuration at context:component-scan

Option 2 (non-web.xml)

1. Delete your web.xml

2. Add Java Config for annotation based Spring MVC

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@EnableWebMvc
@Configuration
@ComponentScan({ "com.mycompany.myproject" })
public class SpringWebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations(
                "/resources/");
    }

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/views/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

}

3. Modify SpringWebConfig with the right package at @ComponentScan

4. Add Java Config for WebApplication. Create a class extending WebApplicationInitializer with required configurations:

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;

    import org.springframework.web.servlet.DispatcherServlet;

    public class MyWebAppInitializer implements WebApplicationInitializer {

        public void onStartup(ServletContext container) throws ServletException {
            AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
            ctx.register(SpringWebConfig.class);
            ctx.setServletContext(container);

            ServletRegistration.Dynamic servlet = container.addServlet(
                    "dispatcher", new DispatcherServlet(ctx));
            servlet.setLoadOnStartup(1);
            servlet.addMapping("/");
        }
    }

Update

Here we had few configuration part that was resulting in this error:

1. DispatcherServlet was configured to accept url with views/*
2. Deployment Descriptor did not have src\main\java to WEB-INF\classes
3. User had Spring 3 running on Tomcat 8 which defaults to JDK-8 and ASM Loader could not load files. Had to move to Spring version 4.0.1-RELEASE
