I have an Spring project with one simple entity and a JPA repository. The entity has three variables: Name (String), active (boolean) and date (java.util.Date). Once deployed, Hibernate creates the table in my MySQL database using varchar, tinyint and datetime. All seems correct but when I create/modify an instance of the entity and call the save() method of the repository, all fields are saved except the date. Is there any know problem storing dates with a JPA repository or meaby I'm doing something wrong?
I'm not putting any code here because is only a simple class and an interface for the repository. Also, the entity is being saved. My problem is only related with Date field (and any other Date field that I could define). Having said this, if anything is needed, just ask.

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.

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'm building the mobile version of the site with different layout. I'm using Spring mobile+Thymeleaf. For testing purposes, I'm getting redirected from main site to mobile version. Here's my web.xml

And mine controller:
public class MainController {
private static final Logger logger = Logger.getLogger(MainController.class.getName());
#RequestMapping(value = "/")
public String HelloWorld(Model model,Device device){
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'm new to Spring, using version 3.2 with Hibernate 4.1.9Final, it seems that #Transactional annotations are being ignored, i've tried to set it on the controller method, service method and dao, no success

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
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?

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";
}
}
I already have an applicationContext file with the following definitions:

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"

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

<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
<property name="contentType" value="text/html; charset=UTF-8"/>
<property name="order" value="1"/>
</bean>
</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"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5"

<param-value>classpath:applicationContext.xml</param-value>
</context-param>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>items</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>items</servlet-name>
<url-pattern>/*</url-pattern>
</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.
