Hibernate -- argument type mismatch when setting an int as an int

I'm doing some refactoring on a legacy application (dependency version information included below), and extracted two related fields from Order to a smaller class, PriorityData. The fields still live in the same table, but are now mapped as a component.
When trying to load an Order, I'm getting an java.lang.IllegalArgumentException: argument type mismatch on one of the re-mapped fields (PriorityData.priority).
Normally, that means a simple type screw-up, but I've checked it several times and am coming up blank as to the cause. The mapping looks correct to me, the database types are correct, etc. Looking for a resolution, or at least a hint as to what I should examime.
The updated Order hbm mapping snippet is below:
Accessors from Order:
public PriorityData getPriorityData() {
return this.priorityData;
}
public void setPriorityData(PriorityData priorityData) {
this.priorityData = priorityData;
}
Accessors from PriorityData:
public int getPriority() {
return this.priority;
}
public void setPriority(int priority) {
this.priority = priority;
}
public Timestamp getPriorityChangeDate() {
return priorityChangeDate;
}
public void setPriorityChangeDate(Timestamp priorityChangeDate) {
this.priorityChangeDate = priorityChangeDate;
}
Database type declarations:
PRIORITY: INTEGER
PRIORITY_CHANGE_DATE: TIMESTMP
Dependencies: Spring 3.2.8, Hibernate 3.5, DB2 9.5

nullPointerException when injecting bean with Spring

I'm new to Spring 3.2.5 and I'm trying to inject a bean in another one as a property, but when I want to use the property it's always null.
I'm using the following configuration:
applicationContext.xml:
<bean id="subscriptionService" class="fake.services.SubscriptionService">
</bean>
<bean id="restController" class="fake.RestController">
<property name="subscriptionService" ref="subscriptionService"></property>
</bean>
RestController.java:
#Path("/")
#Secured("ROLE_USER")
public class RestController {
protected ISubscriptionService subscriptionService;
/**
* #return the subscriptionService
*/
public ISubscriptionService getSubscriptionService() {
return subscriptionService;
}
/**
* #param subscriptionService the subscriptionService to set
*/
public void setSubscriptionService(ISubscriptionService subscriptionService) {
this.subscriptionService = subscriptionService;
}
}
ISubscriptionService.java:
public interface ISubscriptionService {
public UUID subscribe();
}
SubscriptionService.java
public class SubscriptionService implements ISubscriptionService {
/**
*
*/
public SubscriptionService() {
}
/**
* Subscribes a user and returns a uuid for the queue
* #return the uuid for the queue
*/
public UUID subscribe() {
return UUID.randomUUID();
}
}
What am I missing?
thanks!
Update:
the error i'm getting:

Have you implemented the ISubscriptionService interface ? Your subscriptionService bean in applicationContext.xml should refer to the implementation of that interface.

I finally solved it, or rather found a way to get it working.
The problem is that jersey crates a new object for each request, and the bean is only injected once at the server start, thus at any subsequent creation of the object by jersey (at request time), the bean is not injected in the new object, and the null pointer exception is returned.
I added the following method to my controller:
/**
* Get the subscription bean
* #return the subscriptionService
*/
public ISubscriptionService getSubscriptionService(ServletContext servletContext) {
ApplicationContext ctx = WebApplicationContextUtils
.getWebApplicationContext(servletContext);
return ctx.getBean("subscriptionService", ISubscriptionService.class);
}
and to call the service, I just do
this.getSubscriptionService(servletContext).subscribe()
Hope it can help other people around

Spring controller called twice while playing video with vlc-plugin

When I play a video using the vlc-plugin and a Spring controller, the controller is called twice and the second time I get the error:

Here is my client side embed element using vlc-plugin:
<div id="videoPlayerContainer">
<embed type="application/x-vlc-plugin" pluginspage="http://www.videolan.org" src="subject/play?subjectId=X" width="500" height="300" />
</div>
Here is my controller:
/**
* Gets stream to the broadcasting video of the subject.
*/
#RequestMapping(method = RequestMethod.GET, value = PLAY)
public void play(final UserEntity sessionUser, #RequestParam("subjectId") int subjectId, HttpServletResponse res) {
String path = null;
try {
SubjectEntity subject = subjectService.getById(subjectId);
path = storageService.getFilePathBySubject(subject, FileType.SD);
if(StringUtils.isBlank(path)) {
logger.warn("Missing path of the '" + FileType.SD + "' file corresponding with the subject '" + subjectId + "': " + path);
res.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
return;
}
File file = new File(path);
res.setHeader("Content-Disposition", "attachment; filename=" + file.getName().replace(" ", "_"));
res.setHeader("Content-Type", "video/mp4");
res.setHeader("Content-Length", String.valueOf(file.length()));
InputStream inputStream = new FileInputStream(file);
ServletOutputStream outputStream = res.getOutputStream();
IOUtils.copy(inputStream, outputStream);
res.flushBuffer();
res.setStatus(HttpStatus.OK.value());
IOUtils.closeQuietly(inputStream);
IOUtils.closeQuietly(outputStream);
// return new FileSystemResource(path);
} catch(Exception ex) {
// ...
}
}
On the second call, the exception is thrown on the line:
IOUtils.copy(inputStream, outputStream);
This is the only controller which is called twice.
I'm using Spring 4.0.6.RELEASE.
The video can be played anyway, but I'm not reassured by this situation...
Anyone has an idea?
Thanks for your help.

dynamic json response: Could not read JSON: N/A (through reference chain) jackson fasterxml

I want to access a REST api with a variable amount of product codes as parameters.
The JSON response will give me a token for every code I submit.
The problem is the root elements of the json response will be the product codes I submitted, so I can't use the standard #JsonProperty annotation in my receiving class.
How to go about this ?!
For instance:
URL: http://example.com/listing?code=123456&code=456789
Response:
{
"123456": {
"code": 123456,
"primaryToken": "4176d70b52c3f3287c7"
},
"456789": {
"code": 456789,
"primaryToken": "6ddsd25a36bdf7fb"
}
}
I call the API like this :
ImageListingResponse response = restTemplate.getForObject(url, ImageListingResponse.class, apiArguments);
And my ImageListingResponse class is :
#JsonIgnoreProperties(ignoreUnknown=true)
public class ImageListingResponse {
private Map<String, ImageResponse> response;
#JsonAnyGetter
public Map<String,ImageResponse> get() {
return response;
}
#JsonAnySetter
public void set(String name, ImageResponse value) {
response.put(name, value);
}
}
ImageResponse :
#JsonIgnoreProperties(ignoreUnknown=true)
public class ImageResponse {
#JsonProperty("code")
private Long code;
#JsonProperty("primaryToken")
private String primaryToken;
...
}
Thanks in advance !
EDIT: forgot the stacktrace :

Isn't it just because you didn't initialize the Map<String, ImageResponse> response field?

ClassNotFoundException YaHP Converter

I'm trying to use YaHP Converter API.
First I want to convert a simple html code, then I will take mine from a filter.
I used maven to import YaHP.
Here what I have :
#RequestMapping("/edition")
public void buildPdf(HttpServletRequest request, HttpServletResponse response)
throws IOException, CConvertException {
String myHtml = "<div><h1>test html</h1></div>";
String htmlContents = myHtml;
CYaHPConverter converter = new CYaHPConverter();
Map properties = new HashMap();
List headerFooterList = new ArrayList();
properties.put(IHtmlToPdfTransformer.PDF_RENDERER_CLASS, IHtmlToPdfTransformer.FLYINGSAUCER_PDF_RENDERER);
OutputStream os = response.getOutputStream();
response.reset();
response.setContentType("application/pdf");
// String[] fname = filename.split("\\\\");
// if (fname[0].equals(filename)) {
// fname = filename.split("/");
// }
String pdfName = "export";
response.setHeader("Content-Disposition", "attachment; filename= \"" + fileName + ".pdf\"");
converter.convertToPdf(htmlContents, IHtmlToPdfTransformer.A4P, headerFooterList, "file:///temp/html/", os,
properties);
response.flushBuffer();
// super.buildPdfReport(request, response);
}
I get :

SEVERE: Error while getting transformer 'org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer' ! : org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer
I would appreciate helping me to resolve my issue.

Add the following dependency
<dependency>
<groupId>com.google.code.maven-play-plugin.org.allcolor.yahp</groupId>
<artifactId>yahp-internal</artifactId>
<version>1.3</version>
</dependency>

You need to add library with class org.allcolor.yahp.cl.converter.CHtmlToPdfFlyingSaucerTransformer to your Tomcat classpath.
For example you could add this library to %CATALINA_HOME%\lib directory.
