All,
A Spring newbie here.
I am trying to build a spring mvc(Sping 4.1.6 release) app. This app does not have a default landing page(like index.jsp, I have removed index.jsp from my app). This app will be called from another app by URL links or directly typing the path. My issue is I am not able to get this working. When I type localhost:8080/app/user.jsp(this is in WEB-INF/jsp folder) or localhost:8080/app/jsp/user.jsp(I would prefer not to use this path though).
Another question: I tweaked the app to have an index.jsp redirecting to user.jsp in the WEB-INF folder(not the WEB-INF/jsp) and the Controller #RequestMapping("/"), the user.jsp loads but the textbox is not displayed.
My web.xml

I am not sure what I am missing in both the scenarios. Thanks.
EDIT: The suggestion by minion solved my issue. Thanks.
There are couple of issues or changes you need to do. Here is the Gist of the issue :
Your spring servlet is mapped to / and the requested url is of the
pattern *.jsp. So it would never hit the controller that you wrote.
So change your controller to like one below.
#Controller
#RequestMapping("/user")
public class userController {
#RequestMapping(method = RequestMethod.GET)
public String initForm(Model model){
user user = new user();
model.addAttribute("user", user);
System.out.println("IIIIIIIIInside user Controller");
return "user";
}
Use the url localhost:8080/app/jsp/user to hit the controller.
}

I think Spring is not able to scan base package: com.mvcform.*
Please let me know what I am missing here.
1) if you configured correct then you must check the json format which you sending to server to save it may be wrong (refere the urlenter link description here)
2) please check your controller controller doesn't have this url "URI [/SpringMVCForm/login.htm]" you have only /login.htm url.
Remove
#RequestMapping("/login.htm")
and keep only
#RequestMapping("/login")
in controller
I am a beginner and trying to run simple code and I encounter the warning No mapping found for HTTP request with URI [/Project_Tracker/] in DispatcherServlet with name 'spring

You can add / to
#RequestMapping(value="/LoginPage.html", method=RequestMethod.GET) like:
#RequestMapping(value= {"/", "/LoginPage.html"), method=RequestMethod.GET)
Or you can create a index page or welcome page in root path. What you met is just there is not a controller method which is mapped to /.
I am trying to learn Spring MVC on NetBeans 8.0.2 using Hibernate and frankly I am stuck. Any help is appreciated. I am only trying to do a very simple "hello world" type site.
Someone would on the first page hit a submit button and the resulting page would have a list of values from the DB. Sounds pretty simple right?
I've included 5 very short files here that will hopefully help you to help me if you are so inclined.
"web.xml", "dispatcher-servlet.xml","index.jsp", "TeamController.java", "secondView.jsp"
The way I understand how Spring MVC should work, using my files, is as follows...
1) Running the project from NetBeans, the index.jsp file is brought up.
This happens because the Web.xml is consulted, which has the following line...
"<welcome-file>redirect.jsp</welcome-file>"
once the redirect.jsp is consulted, we see that it has the following...
"<% response.sendRedirect("index.htm"); %>"
so with that redirect we go back to the web.xml which has the following...
"<servlet-name>dispatcher</servlet-name>"
"<url-pattern>*.htm</url-pattern>"
so with that request coming in as index.htm it is to be handled by the dispatcher servlet.
In the dispatcher servlet's config file, the view resolver will add the following...
p:prefix="/WEB-INF/jsp/"
p:suffix=".jsp" />
so index.htm gets changed to /WEN-INF/jsp/index.jsp and that page is brought up.
2) At this point the index.jsp is brought up. The only thing in this file is a form with a submit button. The intent is just to have someone press the button and info from the DB is returned on screen. I have Hibernate as part of this web project and I have created a java class "Team.java" based on a DB table "Team". It is populated with a few records.
Currently what I am seeing is that once the index.jsp comes up and I hit submit, it is giving a 404.
This is the URL shown for the form
"host:port/HelloWebFour/index.htm "
if I do a view source it shows it as the index.jsp. When I hit submit it gives a 404 with this url
"host:port/HelloWebFour/team? "
btw, "HelloWebFour" is the name of my project in NetBeans.
I am not sure what is happening, if my understanding is right or if I need to add anything. any help is appreciated...
The very short code files are below...

As far I see you Submiting to "/HelloWebFour/team but your only request handler method is mapped to /team, try to submit to just /team. I don't use any prefix on Dispatcher mapping so can be a missed .htm on url combining with the unknown request url /HelloWebFour/team.
Then if one of above solutions work, your method may fail because you are expecting a modelAttribute named as "SpringWeb" of type Team, but your form actually dont post any data and it's modelAttribute is mapped to "command", the default value, so removing this can possibly remove a further error if occurs.
I'm new to Spring.I have made an application named "BookWorkshop" using spring-3.1 by following MVC architecture.but as soon as I'm hitting the
url:http://localhost:8087/BookWorkshop I'm getting the error as follows:

can anyone give any solution to this?????????????
Try this:
<property name="commandClass">
<value>
com.edifixio.model.UserBook
</value>
</property>
you can download a fully working spring mvc form based example from here . You can then modify that example in whatever way you want.
I'm trying to create a simple Spring 3 application and have the following files. Please tell me the reason for this error
Below is my web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>
Below is my index.jsp

<form:input path="password" id="password"/><br/>
<input type="submit" value="submit"/>
</form:form>
Go to Registration Page

Below is my dispatcher-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
</bean>
<bean name="/login" class="com.infy.controller.LoginController"/>
</beans>
This is the LoginController.java
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class LoginController {
#RequestMapping(value="/login", method=RequestMethod.POST)
public ModelAndView loginAction(#ModelAttribute("loginBean")LoginBean bean){
return new ModelAndView("success", "success", "Successful Login");
}
}
And finally my LoginBean
public class LoginBean {
private String userName;
private String password;
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
You'll have to have a ContextLoaderListener in your web.xml - It loads your configuration files.
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
You need to understand the difference between Web application context and root application context .
In the web MVC framework, each DispatcherServlet has its own WebApplicationContext, which
inherits all the beans already defined in the root WebApplicationContext. These inherited
beans defined can be overridden in the servlet-specific scope, and new scope-specific
beans can be defined local to a given servlet instance.
The dispatcher servlet's application context is a web application context which is only applicable for the Web classes . You cannot use these for your middle tier layers . These need a global app context using ContextLoaderListener .
Read the spring reference here for spring mvc .
And if you would like to use an existing context, rather than a new context which would be loaded from xml configuration by org.springframework.web.context.ContextLoaderListener,
