I have tried multiple times, but still I am getting these issue, but unable to understand from where this is arising.

org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI
[/Demo/greeting.html] in DispatcherServlet with name 'demoServlet'
My web.xml
<servlet>
<servlet-name>demoServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>

</init-param>
</servlet>
<servlet-mapping>
<servlet-name>demoServlet</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
And My servlet-config.xml
<mvc:annotation-driven />
<context:component-scan base-package="com.demo.controller" />
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/content/" p:suffix=".jsp"></bean>
My HelloController
#Controller
public class HelloController {
#RequestMapping(value ="/greeting")
public String sayHello(Model model){
model.addAttribute("greeting","Hello World !");
return "hello";
}
}
I have no idea but this solved my problem!! [Would Like to know the reason for the original problem]
I changed
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
to
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
and it ran perfectly fine :)
Try to replace:
#RequestMapping(value ="/greeting")
with:
#RequestMapping(value ="/greeting.html")

I try to modify server list (or default server) on Swagger UI.
1/ On Spring (Not Spring Boot) configuration class I add this :
#Bean
public OpenAPI customOpenAPI() {
log.info("<<<customOpenAPI>>>");
Server server = new Server();
server.setUrl("http://localhost:8091/eatery_spring_rs/rs/");
return new OpenAPI()
.servers(List.of(server));
}
2/ But I never obtain result on Swagger UI, no server is added :
3/ Maven dependencies are :
<!--SWAGGER-->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springdoc/springdoc-openapi-ui -->
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.7</version>
</dependency>
<!-- END -->
5/ Question :
Is it possible to change context path, or add server URL, by program ?
6/ I can affine the description of problem
The context path of application is not complete
It is a Spring 5.3 application, start with web.xml in App Server.
like Tomcat, ...
This is the web.xml definition :
`
<servlet>
<servlet-name>springServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:servlet-service.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springServlet</servlet-name>
<url-pattern>/rs/*</url-pattern>
</servlet-mapping>`
This mean that the real context path is : [app.context]/rs but in the case of :
#Bean public Docket api(ServletContext servletContext) {
servletContext is equal to [app.context] NOT to [app.context]/rs
It's help ?
I am entering Spring MVC but it does not redirect me to the url with the RequestMappin, it only does it with the main page but with the others if I add it manual it does not execute, what can I have wrong?
the url that I use to enter login is http://localhost:8080/spring-mvc/login
#WebServlet(urlPatterns = "/login.do") <------------------This work
public class LoginServlet extends HttpServlet {
private LoginService service = new LoginService();
#Controller
public class LoginController { <!---------------------------This not-->
#RequestMapping(value="/login")
#ResponseBody
public String decirHola() {
return "Hola a todos";
}

I am attempting to use Weld with Tomcat7 and Jersey, and in my log files I am seeing this:
org.jboss.weld.exceptions.IllegalStateException: WELD-001304: More than one context active for scope type javax.enterprise.context.RequestScoped
The application deploys properly and I only see this when attempting to hit on my Jersey endpoints.
Here is the pertinent parts of the pom.xml

I am uber-confsued what could be going wrong.
I have created simple spring security demo with REST webservice.
I have spent lot of hours on It.Need strong pointers regarding simple working spring security for rest webservice with latest versions.
My Controller is
#Controller
public class RestContoller {
#RequestMapping(value = "/countryJSONProduce", method = RequestMethod.GET)
public ResponseEntity<CountryDetail> getCountryJSON() {
CountryDetail countryDetail = new CountryDetail("Values");
ResponseEntity<CountryDetail> rentity = new ResponseEntity<CountryDetail>(countryDetail, HttpStatus.OK);
return rentity;
}
#RequestMapping(value = "/countryJSONConsume", consumes = MediaType.APPLICATION_JSON_VALUE, method = RequestMethod.POST)
public String consumeJSON(#RequestBody CountryDetail countryDetail) {
System.out.println("Country Detail Example");
return "home";
}
}
web.xml is

When I Run the code sometimes it shows popup in my Eclipse Mars INTENAL
browser for user and password.when i put my credentials it will goes to
localhost:8080/SpringMavenRest2/ welcome page ok.when I hit the
url localhost:8080/SpringMavenRest2/hello/countryJSONProduce
which is calling my first service.. it is showing the Error :Access to
the specified resource has been forbidden.403
Even I put user name and
password as basic auth.Now I am testing this second url FROM CHROME
POSTMAN CLIENT.
I am using this configuration Java 1.8 ,Tomcat 8.0
spring.version4.1.0.RELEASE ,springsecurity.version 4.0.2.RELEASE.
and maven 3.3
Its
working well without authentication.Could you give any best referenced demo
for spring security with basic authentication. I have refered this also
http://www.mkyong.com/spring-security/spring-security-hello-world-example/
Try this :
<security:intercept-url pattern="/hello/**" access="hasRole('ROLE_USER'') "/>
and / or
<security:intercept-url pattern="/**" access="hasAnyRole('IS_AUTHENTICATED_ANONYMOUSLY','ROLE_USER')"/>
I can't seem to get my jersey resources recognized in my app. According to everything I read online, there are two possible cases where this may happen.
There is no valid package declared in the web.xml under com.sun.jersey.config.property.packages.
This is my web.xml:
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
metadata-complete="false">
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>
com.sun.jersey.spi.container.servlet.ServletContainer
</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>my.package</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
:
2. There is no valid resource class in my.package.
My resource class:
package my.package;
import javax.ws.rs.Path;
import javax.ws.rs.GET;
import javax.ws.rs.core.Response;
#Path("/")
class MyClass{
#GET
public Response asdf(){
return Response.ok().build();
}
#Path("/test")
#GET
public Response test(){
return Response.ok().build();
}
}
As far as I can tell, neither of these two conditions are satisfied.
For the sake of completion, here are my dependencies:
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>jsr311-api</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>com.sun.jersey</groupId>

<version>1.17</version>
</dependency>
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-servlet</artifactId>
<version>1.17</version>
</dependency>
Any ideas as to why I might be getting this error?
#Path("/")
class MyClass{
The class isn't visible to Jersey. Try changing it to (note the addition of "public"):
#Path("/")
public class MyClass{
