Im trying to show the .jsp page, i have set the Controller class and the web.xml and servlet.xml. When i run it shows "404 page not found". Can you help me find mistake, step by step.
Im using intellij idea 2019, tomcat 9
#Controller
public class HomeController {
#RequestMapping("/")
public String showHome(){
return "nesto";
}
}
This is web.xml and servlet.xml

Change

to
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
You missed id="viewResolver"
adding this property to your "InternalResourceViewResolver" bean might help you

I started learning Spring MVC.I connected all required dependencies with maven and downloaded Tomcat.But when i run Tomcat my jsp file is not opening. What the problem? Annotations seem to be correct
My applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>
<context:component-scan base-package="com.ildar" />
<mvc:annotation-driven/>
<bean

Controller class:

public class MyController {

public String showMyView(){
return "first-view";
}
}
And when I run Tomcat , i just see eror 404 not found in browser
I created a project named "Testing" using maven in eclipse j2ee. I created a web.xml file in WEB-INF folder as follows :
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I have a controller called helloworldcontroller as follows
package com.spring.trial;
import org.springframework.beans.factory.annotation.Autowired;
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.spring.trial.access.Categories;
#Controller
public class HelloWorldController {
String message = "Welcome to Spring MVC!";
#Autowired
Categories categories;
#RequestMapping("/hello")
public ModelAndView showMessage(
#RequestParam(value = "name", required = false, defaultValue = "World") String name) {
System.out.println("in controller");
ModelAndView mv = new ModelAndView("helloworld");
mv.addObject("message", message);
mv.addObject("name", name);
return mv;
}
}
Okay now for the triky part....
1)i went through various tutorials online and in some sites the web.xml file has context params that pass the dispatcher-servlet to the context loader class. Does this mean that all the beans in the dispatcher servlet be initialised and autowired . And does it mean that the dispatcher servlet context is now the root application context??
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</context-param>
<!-- this class is responsible for auto-wiring all the beans together in
spring -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
In some sites the web.xml file is intialised as follows:
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/application-context.xml
</param-value>
</context-param>
<!-- Configurations for the DispatcherServlet application context (child context) -->
<servlet>
<servlet-name>spring-mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring-mvc-servlet.xml
</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>spring-mvc</servlet-name>
<url-pattern>/admin/*</url-pattern>
</servlet-mapping>
2) so again what is happening in this web.xml file?? is it loading 2 different contexts one for root and the other for dispatcher servlet??
and in case 2 they hace application-context.xml so on a jsp page i can easily retrieve a bean using
applicationContext context = new classpathxmlapplicationcontext("application-context.xml);
myclass mclass = (myclass)context.getbean("mclassname");
but in case I(first web.xml file that i posted on top) i dont have any application context so how am i supposed to retrive bean on my jsp page?? I just have the dispatcher and all the beans are declared in the dispatcher. please help me i am so confused ryt now.....
I have a small issue in request mapping,
I have controllerA with request mapping as
#Controller
#RequestMapping(value={"login/formA.html", "B/formB.html", "C/formC.html"})
public class ControllerA {
}
I need to create one more controller without disturbing the existing controller,
request mapping for secound controller like below
#Controller
#RequestMapping(value={"X/test1", "Y/test2", "Z/test3"})
public class ControllerB {
}
How can I configure the spring-servlet.xml to configure the above scenario and to make it work.
I have the web.xml:

Plese do give me suggestion to resolve this issue , struck with few days.
Thanks in Advance.
Add one more servlet mapping in web.xml like given below
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/public/*/*</url-pattern>
</servlet-mapping>
I'm creating a project with Spring 3.2.0, PrimeFaces 3.3.1, Mojarra 2.1.11 and then Spring Security 3.1.1.
My problem is the whenever an ajax call is fired by PrimeFaces, like for example in table pagination, the screen components are not refreshed.
EDIT #4
Whenever an ajax called is fired, an status 302 is returned from the server and the page is refreshed
I think the problem is related to Spring security, this are my settings:
<security:http entry-point-ref="authenticationEntryPoint" pattern="/spring/**">
<security:anonymous />
<security:http-basic />
<security:custom-filter position="FORM_LOGIN_FILTER" ref="authenticationProcessingFilter" />
<security:logout logout-url="/spring/logout" logout-success-url="/spring/login?logout=true" />
<security:intercept-url pattern="/spring/login" access="ROLE_ANONYMOUS,ROLE_USER,ROLE_ADMIN" />
<security:intercept-url pattern="/spring/logoutSuccess" access="ROLE_ANONYMOUS,ROLE_USER,ROLE_CLIENT" />
<security:intercept-url pattern="/spring/intro" access="ROLE_ANONYMOUS,ROLE_USER" />
<security:intercept-url pattern="/spring/flows/admin_main_flow/**" access="ROLE_ADMIN" />
<security:intercept-url pattern="/spring/flows/client_main_flow/**" access="ROLE_CLIENT" />
</security:http>
<security:http security="none" pattern="/javax.faces.resource/**" />
<security:http security="none" pattern="/ajax/**" />
<security:http security="none" pattern="/static/**" />
<security:http security="none" pattern="/resources/**" />
This happen just after the login so I don't think the session should be already expired.
EDIT #4 end
I stripped down the application to a minimum and tried this code:
<h:form id="testAjax" >
<h:panelGrid columns="4" cellpadding="5">
<h:outputLabel for="test" value="test:" style="font-weight:bold"/>
<p:inputText id="test" value="#{testBean.test}" />
<p:commandButton value="Submit" update="#form"/>
<h:outputText value="#{testBean.test}" id="display" />
</h:panelGrid>
</h:form>
note that I double checked that no forms are nested, I tried both "process" and "update" with #form or the elements id.
What happens is that the setter of TestBean is called, the attribute setted, but then the getter is never called again to display the new value. This are the logs on server side:
org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'Spring MVC Dispatcher Servlet' processing POST request for [/TryAjax/spring/WEB-INF/login.xhtml]
org.springframework.web.servlet.handler.SimpleUrlHandlerMapping - Mapping [/WEB-INF/login.xhtml] to HandlerExecutionChain with handler [org.springframework.web.servlet.mvc.UrlFilenameViewController#2f46ccac] and 1 interceptor

org.springframework.faces.mvc.JsfView - View rendering complete

Please if you see anything wrong or you have any idea help me, this issue is bugging me from days. Thank you!
EDIT #1
I add the code for the backing bean and the webflow code where I declare it:
public class TestBean implements Serializable {
private String test = "xxx";
public String getTest() {
return test;
}
public void setTest(String test) {
this.test = test;
}
}
<view-state id="home" view="../views/adminHome.xhtml">
<on-entry>
<evaluate expression="textManager.getTest()" result="viewScope.test"/>
</on-entry>
</view-state>
Now this of testBean is just the simplest test case I can make that doesn't work, the main problem I have is that no ajax call works, for example pagination for tables, adding or removing or modifying an element of a datatable, tabView etc.
I generally create the beans for the page and put them in the viewScope or flowScope, this also for lists of data coming from the database. I tryed also having the bean managed by Spring with scope Session but it doesn't work neither. Another note is that the default value display on the page correctly.
EDIT #2
using firebug and the eclipse debug i see this:
Initial value of TestBean.test is "xxx", I change to aaa and press submit.
An ajax post request is sent to the server:
javax.faces.ViewState e2s1
javax.faces.partial.ajax true
javax.faces.partial.execu... #all
javax.faces.partial.rende... testAjax testAjax:display
javax.faces.source testAjax:testButton
testAjax testAjax
testAjax:test aaa
testAjax:testButton testAjax:testButton
When the POST is sent I firt debug a call to TestBean.getTest() and then a call to TestBean.setTest("aaa") that has the correct value.
At this point I would expect another call to TestBean.getTest() when the response is built but the call does not happens and the response does not contain the correct value but the old value "xxx".
If now I refresh the page the getter is called and the new value "aaa" is displayed correctly.
EDIT #3
I still can sort this out. I noticed now with firebug an unexpected behaviour:
when I click the command button 2 requests are sent to the server, a POST and a GET.
The POST is sent first and return an status "302 Moved Temporarily", then the GET start and return a response without the updated data. Anyone knows what status 302 means in this case and what could be the cause?
Debugging in the same way the primefaces demo only a POST request is fired that return no status 302
Thank you
You need to add a parameter to the flow-executor to disable the redirect to the same state. The configuration becomes:
<webflow:flow-executor id="flowExecutor" flow-registry="flowRegistry">
<webflow:flow-execution-listeners>
<webflow:listener ref="flowExecutionListener" />
<webflow:listener ref="facesContextListener"/>
<!-- <webflow:listener ref="flowFacesContextLifecycleListener" />-->
</webflow:flow-execution-listeners>
<webflow:flow-execution-attributes>
<webflow:redirect-in-same-state value="false"/>
</webflow:flow-execution-attributes>
</webflow:flow-executor>
This prevents the flow executor to refresh the page completely after the ajax request is sent.
When you integrate JSF with Spring then your JSF managed beans become Spring beans. This is why Spring includes their own implementation of an ELResolver so that you can reference these Spring beans from within EL expressions.
Unfortunately though the only scopes that Spring supports out of box are #Request, #Session and #Application.
Fortunately a simple implementation of ViewScope that integrates with Spring can be integrated into your application. Cagatay Civici, the lead developer at PrimeFaces wrote a blog article showing an example of a simple ViewScope implementation that can be easily integrated into your application.
http://cagataycivici.wordpress.com/2010/02/17/port-jsf-2-0s-viewscope-to-spring-3-0/
With a managed bean that is view scoped then your beans will have enough persistence to dynamically render page elements on ajax updates.

Solved my problem.
I was using org.springframework.web.servlet.handler.SimpleUrlHandlerMapping for navigation with JSF 1.x RichFaces 3.x.
When moving to JSF 2.x and PrimeFaces/RichFaces 4 the ajax aspects of the DataTables did not work (e.g. displayed but would not sort)
Adding this xml worked like magic (as it would need to since I don't know what I am doing)
I'm using spring mvc 3 along with webflow 2. I have been following online resources and have been trying to get an example working. I am unable to get the webflow url mappings to work. It is only the webflow that is not working, the mvc part is working fine.
The error I keep getting is:
No mapping found for HTTP request with URI [/Project2Admin/pizza] in DispatcherServlet with name 'appServlet'
I have pasted my servlet-context.xml below.
Your help is much appreciated!

Try changing your FlowHandlerMapping to
<beans:bean
class="org.springframework.webflow.mvc.servlet.FlowHandlerMapping">
<beans:property name="flowRegistry" ref="flowRegistry" />
<beans:property name="order" value="-1" />
</beans:bean>
You are using the annotation driven configuration for Spring MVC which registers a default HandlerMapping for you, and I suspect it doesn't fall through to the next HandlerMapping. This has previously been reported as an issue. You want the WebFlow FlowHandlerMapping to come first - so you set the order to -1. This is what we have in our configs.
I managed to solve the problem by creating a dispatcher servlet for webflows. I'm not sure this is the ideal solution, but it works. Both mvc and webflows are now working fine.
If someone knows a more graceful way to handle this.. i.e. use only one dispatcher servlet to handle mvc and webflow calls, please post an answer, your help would be much appreciated.
thanks!

I think the problem here is with two different view resolvers in your servlet-context.xml file.
Please remove the InternalResourceViewResolver and put the viewClass, prefix and suffix properties in the TilesViewResolver bean.
According to me this should solve your problem.
Cheers.
everything is working fine for me with both WebFlow and Spring MVC
here is part of my my web.xml:
<servlet>
<servlet-name>web-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>

<url-pattern>/public/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>web-dispatcher</servlet-name>
<url-pattern>/error/*</url-pattern>
</servlet-mapping>
and my web-dispatcher:
<bean id="viewNameTranslator" class="org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator" />
<bean id="basicViewResolver" class="org.springframework.web.servlet.view.ResourceBundleViewResolver" >
<property name="basename" value="views"/>
</bean>
<!-- Resolves logical view names returned by Controllers to Tiles; a view name to resolve is treated as the name of a tiles definition -->
<bean id="tilesViewResolver" class="org.springframework.js.ajax.AjaxUrlBasedViewResolver">
<property name="viewClass" value="org.springframework.webflow.mvc.view.FlowAjaxTilesView"/>
</bean>
<!-- Configures the Tiles layout system -->
<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">

<!-- Flow views -->

</property>
</bean>
hope this helps
