I'm having problems getting Jackson to work in my Spring app.
I'm using
Spring MVC 3.1.2
Jackson 1.9.1 mapper asl
I've added the Jackson library to /WEB-INF/lib/ folder and added to my spring config file.
spring-config.xml

#RequestMapping(value = "/get_json", method = RequestMethod.GET, headers = "Accept=*/*")
public #ResponseBody List<String> getTechList() {
List<String> countryList = new ArrayList<String>();
countryList.add("test");
return countryList;
}
When i go to localhost:8888/get_json i get a error 406.
I have tried a solutions on the internet but none of them seem to work. Any help would be appreciated!
PS: I use Spring MVC in combination with Google App Engine and Spring Security.
I have got it working after 2 days. I forgot to add jackson-core-asl-1.9.10 to my library and when i made a request using jQuery, everything worked. It does not working going to the link in a browser but i guess thats fine for now.

I have my hibernate entity manager factory declared in jpa.xml, hazecast configured in hazelcast.xml and I have domain model setup and I have corresponding componentContext.xml present in the domain model project where my entity manager factory class is implemented in it. But the problem I am
facing is that my bean in componentContext.xml is getting intialized in a loop (observed from hibernate.log)
My Web.xml has only com.sun.faces.config.ConfigureListener listenere configured.

I have tried debugging multiple times but I am not able to figure out why the initialzing is happening multiple times (as if in a loop). Any pointers greatly appreciated!
I finally figured out the reason! There was an additional #ComponentScan annotation specified in the application configuration class which was causing the loop to be triggered.

I think the problems may be located on the returned view name. Since the view name is the same as the /index path, so maybe it will be dispatched by spring dispatcher again. Maybe you can try to change the view as another name to have a try.
I work with Spring MVC. I have a dynamic web project.
Project structure is
I have a correos.properties in /WEB-INF/classes.
correos.properties is
correosalida = xxx

}
Value of correosalida is null.
How can I get a property from correos.properties?
Did you try to reach the file using classpath?
It should be like this:
<context:property-placeholder location="classpath:correos.properties" order="1" ignore-unresolvable="true" />
EDIT:
Try to load this way:
<util:properties id="correos" location="classpath:correos.properties"/>
And shouldn't be with a "#" instead of a "$"?
#Value("#{correos.correosalida}")
Please help me! I am modifiyng my spring mwc application. But I am not able to understand what does mean one tag in the webmvc-config.xml file . I mean why it is written common.index and not common/index ? In fact into the directory view/common there is the file index.jsp.

From spring 3.0 documentation
This tag is a shorcut for defining a ParameterizableViewController
that immediately forwards to a view when invoked. Use it in static cases
when there is no Java Controller logic to execute before the view generates
the response
I'm using
<mvc:resources mapping="/resources/**" location="/resources/" />
To handle static content in my SpringMVC app. This works fine. I am able to upload images and retrieve them within the application using the "/resources" url .I want to use an jpeg for a background image in a jsp, so I though I would simply drop the jpeg into the resources folder in my workspace. However, there is no resource folder in my workspace folder anywhere. Where is spring storing these images? How do I get to this folder to add my background image?

The call to the save image method
saveImage(context.getRealPath("/resources/" + person.getId() + ".jpg"), image);
However, there is no resource folder in my workspace folder anywhere
It should be present in WebContent. If its not there then <mvc:resource> is not being used to serve static content.
How do I get to this folder to add my background image?
Create resources folder under WebContent and put your images into it. Access the images by /resources/foo.jpeg.
