and the link of the program https://github.com/mendlik/spring-mvc-thymeleaf

I search with this error on google but I can't find any problem with programs side.

tomcat users file shows,

<role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>

Have you included maven tomcat plugin in your pom.xml? build section of your pom shoul be like :

<build>
   <resources>
      <resource>
          <directory>src/main/resources</directory>
          <filtering>true</filtering>
          </resource>
   </resources>
   <plugins>
      <!-- Maven Tomcat Plugin -->
      <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>tomcat-maven-plugin</artifactId>
    <configuration>
        <url>http://127.0.0.1:8080/manager</url>
        <server>TomcatServer</server>
        <path>/mkyongWebApp</path>
    </configuration>
       </plugin>
    <plugins>
</build>

You also have to add an user with administrator access right for Tomcat. Edit the file – “%TOMCAT_PATH%/conf/tomcat-users.xml“ and add role manager for user tomcat.

<role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/>
  <user username="tomcat" password="tomcat" roles="tomcat,manager"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
