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

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 !

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

IllegalStateException: getOutputStream() has already been called for this response on retrieving image

i wanted to display image that present in a specific folder. when i send request from server, on client side i am getting following exception "**getOutputStream() has already been called for this response "
This is HTML code
<td><img id="imagePreview" src="../catalogue/displayCatalogueImage.action?catalogueTitleNumber=${imageDisplay}" alt="Item Image" width="96" height="80"/></td>
Hear " catalogueTitleNumber " is unique Name of image
This Is My Controller
#RequestMapping("/catalogue/displayCatalogueImage.action")
public String getDisplayImage(String catalogueTitleNumber, HttpServletRequest request) {
try {
System.out.println("Image Display Title number = > "+catalogueTitleNumber);
if(catalogueTitleNumber!= null && !"".equals(catalogueTitleNumber)){
File image = new File("images/"+catalogueTitleNumber);
BufferedImage originalImage=ImageIO.read(image);
ByteArrayOutputStream baos=new ByteArrayOutputStream();
ImageIO.write(originalImage, "jpg", baos );
byte[] imageInByte = baos.toByteArray();
request.setAttribute("imageInByte", imageInByte);
baos.close();
}
} catch (Exception e) {
e.printStackTrace();
}
return "catalogue/displayCatalogueImage";
}
This is " displayCatalogueImage.JSP " page which help to write the image for requested img tag
<%#page import="java.io.OutputStream"%>
<%#page import="java.sql.Blob"%>
<%
try{
byte[] image = (byte[]) request.getAttribute("imageInByte");
response.setContentType("image/png");
OutputStream os = response.getOutputStream();
os.write(image);
os.flush();
os.close();
out.clear();
out=pageContext.pushBody();
} catch(Exception ex) {
out.println("Unable To Display image");
out.println("Image Display Error = " + ex.getMessage());
}
%>
At beginning (only one time ) it showed image after words i am keep getting this exception
Hear you can notices that i am calling '.write' for two times one in controller and another one in jsp page (in jsp .write help to write the byte code and in controller it helps to get byte code of a image ) i tried to avoid '.write' in controller, it not gave any ERROR but no use...!
i.e
private byte[] image_byte_data(BufferedImage image)
{
WritableRaster raster = image.getRaster();
DataBufferByte buffer = (DataBufferByte)raster.getDataBuffer();
return buffer.getData();
}
i was tried by calling above method in controller and initialized to byte[ ] even the byte variable got byte code of a image but jsp page code failed to write...?
any help will be appreciated, Thanks.

If you're just trying to send back the image data in response to a client image request, don't use a JSP. It doesn't really make sense because you're not returning any markup. Just write the image data straight to the output stream from the controller. Here's an example, refactored a little:
#RequestMapping("/catalogue/displayCatalogueImage.action")
public ResponseEntity getDisplayImage(String catalogueTitleNumber, HttpServletResponse response) throws Exception {
System.out.println("Image Display Title number = > "+catalogueTitleNumber);
if (StringUtils.isNotEmpty(catalogueTitleNumber)) {
response.setHeader("Content-Type", "image/png");
FileInputStream fin = new FileInputStream("images/"+catalogueTitleNumber);
ServletOutputStream out = response.getOutputStream();
IOUtils.copy(fin, out);
IOUtils.closeQuietly(fin);
response.flushBuffer();
return new ResponseEntity(HttpStatus.OK);
}
return new ResponseEntity(HttpStatus.NOT_FOUND);
}

You are first retrieving the OutputStream and then still mess around with the Writer out a couple of lines later.
You are not allowed to do both.
Simply remove the out calls and things should be fine,

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.
