Hello guys i have been playing around with spring mvc and hibernate. But now i am getting an error when trying to connect both hibernate and spring with XML configuration. I get this error below:
03-Nov-2015 22:22:19.675 WARNING [RMI TCP Connection(2)-127.0.0.1] org.springframework.web.context.support.XmlWebApplicationContext.refresh Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personService' defined in ServletContext resource [/WEB-INF/services.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/services.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Error accessing stax stream
I created my webapp folder in src/main. in my webapp folder i created WEB-INF folder. And WEB-INF folder contained files: service.xml, dispatcher-servlet.xml. Now for my hibernate.cfg.xml, it was placed in src/main folder structure. But when i try to add it in the service.xml upon loading the dispatcher, my hibernate.cfg.xml seems not to be found. Does anyone know why? This is where i am having trouble:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="" />
</bean>
I can't seem to find the value of configLocation. Has anyone encountered this issue.
Below is my web.xml configuration:

I fixed my error by placing hibernate.cfg.xmlin the root directory of WEB-INF. That is placed in webapp folder and solved my issue.
you have already defined "DataSource" bean, I guess you don't need to configLocation property.
you can refer below link for more options http://www.mkyong.com/spring/maven-spring-hibernate-mysql-example

I am new to spring. And I have encounter an error on my spring application. It says :
GRAVE: Servlet [dispatcher] in web application [/web-customer-function] threw load() exception

I have beean dealing with this for a long time now... It has been 5 days. And this is what I have done...
Deployment Asssembly > Add lib folder to path
Stop,clean or/and delete server
Rewrite entire code
Download the org.springframework.web.servlet.DispatcherServlet and try to run again.
I would appreciate the help to all if possible.
This is my Web.xml

Thank you all for the help it made my think again. So I refactor the code from zero checked the libraries and it ran smoothly. So the issue was with the libraries because after refactoring the code it did not work. But checking the libraries it worked.
I am building a Spring MVC Web application. I have created applicationContext.xml file. I am trying to connect to mysql database. But when I define datasource bean in applicationContext.xml the tomcat server starts and it says 404- resource not found.
If I remove all the beans from the applicationContext.xml the project runs properly.
What am I doing wrong? It is said that datasources should be defined in the applicationContext.xml but is there other way to define datasource?
Here is my applicationContext.xml file.

Can you please point out what am I doing wrong here?
san your problem is most likely to be in <context:property-placeholder location="jdbc.properties" /> it should be like this <context:property-placeholder location="classpath:/jdbc.properties" /> i am assuming that the application can not start because there is an error in the listener (the listener can not find the jdbc.properties)i think that you have put jdbc.properties in your classpath because you probably wont put jdbc.properties in the web folder making it accessible to every one can access to your application

And mine controller:

logger.info("Device is "+device);
if(device.isNormal()){
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" />
<constructor-arg value="/studentacc" />
</bean>
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?
26027 ["http-bio-8080"-exec-6] DEBUG org.springframework.web.servlet.DispatcherServlet - Could not complete request

views.properties
pdfPrinter.(class)=library.controller.DummyController
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
I have an existing Spring application that does some server side processing. I am trying to create a webapp for this particular application and chose SpringMVC to serve my purpose.
I created a display controller as follows:
#Controller
#RequestMapping("/items")
public class ItemDisplayController {
private static final Logger LOGGER = Logger.getLogger(ItemDisplayController.class);
private static final String ITEMS_REDIRECT = "redirect:/item/items";
#Autowired
private ItemDisplay itemDisplay;
#RequestMapping
public String listItems(ModelMap model) {
if (LOGGER.isInfoEnabled()) {
LOGGER.info("List all items");
}
List<ItemDetail> itemDetails = itemDisplay.getAllItems();
model.addAttribute("itemDetails",itemDetails);
return "items";
}
}

In my *servlet.xml, I have defined the ViewResolver as follows:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

<mvc:annotation-driven/>
<context:annotation-config/>
<context:component-scan base-package="com.acme.item"/>
<bean id="primaryViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="suffix" value=".jsp"/>
<property name="contentType" value="text/html; charset=UTF-8"/>
<property name="order" value="1"/>

</beans>
And in the web.xml, I have the context-param defined:
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</listener>

</servlet-mapping>
</web-app>
When I run my application, the itemDisplay is not wired up and on the debugger it is showing up with a null value.
Can somebody point out what I may be doing wrong here? In an ideal world, I would assume that annotating the itemDisplay with #Autowired in the controller would help resolve the implementation of the interface.
Only thing I can think of is, ContextLoaderListener does not complain if the applicationContext.xml is not found, Let's try this add classpath*:applicationContext.xml also make sure applicationContext.xml is run time class path of the server
Here is an excellent article that provides a good insight into spring classpath resource.
Your files looks up fine at quick glance. As long as there is only one bean with of ItemDisplay type in your context it should be autowired by type, otherwise you should get error in log file.
One small thing I noticed, which is probably unrelated to your particular issue, is that you map your 'items' controller to all files in web.xml. Usually you would want it to map to particular type of files only - say *.htm so it won't get called for resources such as images etc.
Not sure if this is a typo in your applicationContext file :
<bean id="itemDisplay" class="com.acme.itemDisplayImpl"/>
Shouldn't the class be com.acme.item.DisplayImpl ?. If the name of class is indeed itemDisplayImpl, then you need to change the component-scan element in *servlet.xml to include the correct package.
