My home
#RequestMapping(value = {"/home", "/"}, method = RequestMethod.GET)
public String showHome(Model model) {
log.info("showHome");
return "home";
}
And Yes I have the file home.jsp in the path src/main/webapp/WEB-INF/views
I'm not able to fixed it, someone can help me please?

Change your request mapping like this..
#RequestMapping(value = "/home", method = RequestMethod.GET)
public String showHome(Model model) {
log.info("showHome");
return "home";
}
and add this in your spring-servlet.xml..
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>

HTTP Status 404 - tomcat 7

I am building a spring + hibernate application. I'm getting a 404 error, when I run the project. The compiler does not show any error messages, it indicates that the application server (tomcat 7) loads the servlet, but does not display the root page indicated in the controller class.
Help please......

404 means, that your tomcat server is getting the request, but does not now how to process the given request path.
In other words you have a bug in your URL or your configuration does not what you want it to do.
We need your configuration and desired URL to help you.

The problem is that you map the dispatcher servlet only to *.html, but you map you Controllers without using the .html suffix.
To make it work, either map you controller differently, ie :
#RequestMapping(value = "/index.html", method = RequestMethod.GET)
public String welcomeHome(){
return "index";
}
OR (and what I would do) :
Map you dispatcher servlet to all requests in web.xml :
<servlet-mapping>
<servlet-name>sdnext</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Then if you want to call your application with a url looking like this :
http://somehost:someport/YourApplication/
Then you'll need to map some controller method like this :
#RequestMapping(value = {"/", "/index"}, method = RequestMethod.GET)
public String home() {
// your code here
}
This way, calling http://somehost:someport/YourApplication/ OR http://somehost:someport/YourApplication/index will result in the same controller method being called.

Spring mobile redirect 404 error

return "hello";
}
return "index";
}
}
Mine webapp folder look like this:
WEB-INF---
|
pages---
|
mobile---
|
index.html
So, the redirecting work just fine,I'm getting redirected to mobile version. But page i'm redirected to is non existing(404). I' just can't see the error. Thank you in advance.

"rotate" the redirect to url to sitename:8080/studentacc/m" because it is likely that "studentacc" is the name of your application in the application server, and therefore it must be the first part.
From a very short look to the API, I would try to use the SiteSwitcherHandlerInterceptor.urlPath(String mobilePath, String rootPath) method with the additional parameter for the rootPath
<bean class="org.springframework.mobile.device.switcher.SiteSwitcherHandlerInterceptor" factory-method="urlPath">
<constructor-arg value="/m" />

Removed hibernate.current_session_context_class=thread and it works. Spring injecting its own session context managing implementation when using Spring transaction support layer?

You are using #Transactional in the controller layer. It should be in your Service layer.
Make Categories.save method #Transactional and you might get this error away.

Try to add <context:component-scan base-package="your package here">
Looks like it just can't find annotations

Spring webmvc chaining viewresolvers gives BeanNotOfRequiredTypeException

I have a simple (sample) web application that i have a problem with if i try chaining multiple viewresolvers. When my application is configured in the way described below, trying to access http://localhost:8080/Library/spring/initApplication will throw the error described below.
It seems as though the InitApplication is erroneously being picked up by the wrong view resolver. If i change the order of the view resolvers everything works, but im still wondering why exactly this error occurs because i cant pinpoint why it happens. Im guessing a configuration issue?

It is certainly because your are mapping your view with a Controller class mate!
pdfPrinter.(class)= you should indicate a View class here!
For example to map a Controller to a jsp View, you will need to proceed like this:
login.(class)=org.springframework.web.servlet.view.JstlView
login.url=/vues/en/login.jsp

have you tried renaming your bean? You may be clobbering an internal bean used by spring
