Am having below enpoint method. Here am struct with processing the Soaprequest.
public JAXBElement<com.schema.get_response.v2.GetResponseType> handleGetresponse(#RequestPayload JAXBElement<Byte> Soaprequest){
.......................................
/* how to process the Soaprequest which contains the byte[] of base64Binary objects*/
}
My webservices is hitting the above endpoint and the Soap request is having JAXBElement byte[] of base64Binary objects.Am facing an issue with processing the above JAXBElement request object and getting the actual request from that. please anyone help me.
I just rewritten the above method declaration like below, it worked out.
public JAXBElement<com.schema.get_response.v2.GetResponseType> handleGetresponse(#RequestPayload JAXBElement<String> Soaprequest){
.......................................
/* how to process the Soaprequest which contains the byte[] of base64Binary objects*/
}
change description:
Declaration changed from JAXBElement<Byte> to JAXBElement<String>

I'd like to migrate a JAX-RS-REST-Restservice (running under Tomcat) to Quarkus.
I could solve most of my problems along the way but I still have a problem with one method.
In this function I do a OTA-download (firmware for a device). I set some headers and the MediaType and the content length.
In the original service my code looked as follows:
public HomeAutomationService
{
...
#Context
private HttpServletRequest request;
...
#GET
#Produces(MediaType.APPLICATION_OCTET_STREAM)
#Path("/v1/DownloadFirmware")
public Response getFirmware()
{
...
response.setHeader("X-OTA-SIGNATURE", signatureString);
response.setContentLength((int) file.length());
response.setContentType(MediaType.APPLICATION_OCTET_STREAM);
return Response.ok(file, MediaType.APPLICATION_OCTET_STREAM).build();
}
}
Unfortunately I can't find anything like a HttpServletResponse in Quarkus.
So I now use a ResponseBuilder to create a Response, where I can add headers as needed:
ResponseBuilder responseBuilder;
However, I am not sure how to instantiate the ResponseBuilder. There is a method to set headers for the ResponseBuilder, but I did not find anything on how to the content length and the content type.
I am not sure if I have to set the content-type since I already use a #Produces-annotation - but what about the content length? Is it set automatically? If no (that's what I guess) how can I set it correctly?
Thanks for reading and answering,
Rudi
You don't need to use #Produces in this case and your return should be something like the code below:
return Response.ok(yourFileBytes[])
.type(MediaType.APPLICATION_OCTET_STREAM)
.header(HttpHeaders.CONTENT_LENGTH, <yourFileLength>)
.header(HttpHeaders.CONTENT_DISPOSITION, "inline; ")
.build();
The code above can be written as:
ResponseBuilder resp = Response.ok(yourFileBytes[]);
resp.type(MediaType.APPLICATION_OCTET_STREAM);
resp.header(HttpHeaders.CONTENT_LENGTH, <yourFileLength>);
resp.header(HttpHeaders.CONTENT_DISPOSITION, "inline; ");
return resp.build();
I am trying to upload Array of Multipart file object using feign client.
This is the service am trying to call using Feign client.
public ResponseEntity<Object> manageFileUpload(#RequestParam("files") MultipartFile[] files)
I tried using,Feign client Annotation,
#FeignClient(value = "UPLOADUTILITIES", configuration = Upload.MultipartSupportConfig.class, fallback = UploadFallback.class)
My Method,
#RequestMapping(name = "upload", value = "/object", method = RequestMethod.POST)
#Headers("Content-Type: multipart/form-data")
ResponseEntity<Object> manageFileUpload(#Param("files") MultipartFile[] files);
I was rewarded by the error,
"message": "Type definition error: [simple type, class java.io.FileDescriptor]; nested exception is com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class java.io.FileDescriptor and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) (through reference chain: org.springframework.web.multipart.support.StandardMultipartHttpServletRequest$StandardMultipartFile[0]->org.springframework.web.multipart.support.StandardMultipartHttpServletRequest$StandardMultipartFile[\"inputStream\"]->java.io.FileInputStream[\"fd\"])",
Then by referring this link.I tried in my client side, the blow code.
public class MultipartSupportConfig {
#Autowired
private ObjectFactory<HttpMessageConverters> messageConverters;
#Bean
public Encoder feignFormEncoder() {
return new SpringFormEncoder(new SpringEncoder(messageConverters));
}
}
Then by the code example, i changed my MultiPart File object into File Object.Now my request got fired, but i got Not a multipart request.
I tried this https://github.com/pcan/feign-client-test#feign-client-test,
I created a class and used the encoder class, and changed my encoder as FeignSpringFormEncoder,
Still I am getting No serializer found error.
Could anyone share a simple client, server example with Array of Multipart file request, using feign cleint. Thanks!
I am trying to run a simple example in Jersey which has a GET method and returns a Custom object.
on calling GET I am getting following error
MessageBodyWriter not found for media type=text/plain
I have looked into few answers on stackoverflow where they are suggesting it to put a default constructor and jackson dependency in pom.xml. I have already done that but no luck. Can some one please suggest what I am doing wrong.
Resource Class
#Path("customdatatyperesource")
public class CustomDataTypeResource {
#GET
public CustomResource1 get(#Context UriInfo ui) {
return new CustomResource1();
}
}
Custom Class
#XmlRootElement
public class CustomResource1 {
#XmlElement
String res;
public CustomResource1() { }
#Override
public String toString(){
return "Custom : "+res;
}
}
pom.xml
Thanks
So I figured out that error is not in the code but in the request sent.
When I send the request with header accept: text/plain
I am getting the error MessageBodyWriter not found for media type=text/plain
The resolution is accept header needs to match with what resource can produce.
In this case our resource is capable of producing XML or JSON
A better and more comprehensive way to write this code would be to put produce annotation on the methods.
#Produces(MediaType.TEXT_XML)
and put correct accept header such as
accept: application/json
I am trying to implement REST Service using XPage REST Service Control. I have opted for "customRESTService".
I would like to emit JSON when this service is requested. I can write logic in Server Side Java Script.
But I noticed that this customRESTService also supports "serviceBean", meaning I can write whole logic in pure JAVA.
I have given below code of the bean. I have declared it in faces-config.xml as well. But it throws exception while rendering. Has anyone used "serviceBean" in customRESTService?
I appreciate any help!! Thanks!!
public class GetApproverJSON{
public GetApproverJSON(){
System.out.println("Instantiating Bean");
}
public String doGet() throws NotesException{
JSONObject mainObj = new JSONObject();;
JSONObject itemObj;
try{
mainObj.put("label", "name");
mainObj.put("identifier", "abbr");
itemObj = new JSONObject();
itemObj.put("name", "");
itemObj.put("abbr", "");
mainObj.accumulate("items", itemObj);
return mainObj.toString();
}catch(Exception e){
System.out.println("Exception occured while generating JSON ");
e.printStackTrace();
return mainObj.toString();
}finally{
}
}

You need to change your code to:
public class GetApproverJSON{ ...}
to:
public class GetApproverJSON extends CustomServiceBean {
#Override
public void renderService(CustomService service, RestServiceEngine engine) throws ServiceException {
HttpServletRequest request = engine.getHttpRequest();
HttpServletResponse response = engine.getHttpResponse();
response.setHeader("Content-Type", "application/json; charset=UTF-8");
// Here goes your code, get the response writer or stream
}
since that's the interface the REST service is expecting. You will need to implement just renderService. You can get the method (GET, POST etc.) from the request object
I've never used the service bean before, I usually create my own parser with a static doGet method very similar to yours and in the doGet property of the custom REST service make a call to the static doGet method I create. But I think (I'm probably wrong on this count) if you use the service bean it has to be an entire servlet like if you wrote your own actual REST Service, and not just the parser portion.
I've created quite a few of the parsers and have found that a list of maps:
List>
is usually the best approach for building the initial data. I then loop through the list to build my JSON. In the Extension Library there is a class called JsonWriter which makes it very easy to build a JSON Object. Use the JsonWriter like:
StringWriter sw = new StringWriter();
JsonWriter jw = new JsonWriter(sw);
jw.startObject();
jw.startProperty("SomeProperty");
jw.outStringLiteral("SomeValue");
jw.endProperty();
jw.endObject();
return sw.toString();
For a full on example you can take a look at the REST service I built for my JQuery FullCalendar demo. While none of the methods are static (I need to track a couple of properties) you should get the basic idea. But what kicks the whole thing off is a call to the writeJson() method. That is invoked in this custom control.
Those examples should get you going on building your own custom JSON parser and emitting that JSON back to your application.
I have an interceptor like this:
public class WebServiceInterceptor extends EndpointInterceptorAdapter {
#Inject
private Jaxb2Marshaller myJaxb2Marshaller;
#Inject
private WebServiceHistoryDao webServiceHistoryDao;
#Override
public boolean handleRequest(MessageContext messageContext, Object endpoint)
throws Exception {
Source payloadSource = messageContext.getRequest().getPayloadSource();
Object unmarshaled = myJaxb2Marshaller.unmarshal(payloadSource);
//EXTRACT XML HERE
//is there a better way than this:
String extractedXml = myJaxb2Marshaller.marshal(unmarshaled);
return true;
}
}
How can i extract the whole xml of envelope (for logging purposes - to write it to the DB)
You don't need to write one, there's an existing one in the API - SoapEnvelopeLoggingInterceptor. See the javadoc.
SOAP-specific EndpointInterceptor that logs the complete request and response envelope of SoapMessage messages. By default, request, response and fault messages are logged, but this behaviour can be changed using the logRequest, logResponse, logFault properties.
If you only need to see the payload, rather than the entire SOAP envelope, then there's PayloadLoggingInterceptor.
