Hi, I have ported the jsonp binding from version 2.0 to version 1.4 and have declared the following service:
<component name="ExpLocComponentP">
<implementation.java
class="com.service.explocp.ExpLocServiceImpl"/>
<service name="ExpLocService">
<tuscany:binding.jsonp uri="/API/locatorp"/>
</service>
</component>
The class has the following method I want to reach:
package com.service.explocp;
import java.util.ArrayList;
public class ExpLocServiceImpl implements ExpLocService {
...
@Override
public void submitQuestion (QuestionDTO qDTO) throws Exception{
try {
qDTO.setSite("EL");
ExpLocCommon.submitQuestion(qDTO) ;
} catch (Throwable _ex) {
LOGGER.error(_ex);
}
}
Remembering that the ExpLocService has the annotation:
@Remotable
public interface ExpLocService {
Now, debugging the error presented when executing the URL:
http://localhost:8080/eed/API/locatorp/submitQuestion?1=[{"userEmailId":";
[email protected]","expertEmailId":"[email protected]
","subject":"hello","question":"test test test test
","isST":"true","searchKeyword":"","expertiseId":"","site":"test"}]
It will go into the code for class JSONPServlet:
...
@Override
public void service(ServletRequest servletRequest, ServletResponse
servletResponse) throws ServletException, IOException {
String jsonRequest = getJSONRequest(servletRequest);
Object[] args = jsonToObjects(jsonRequest);
Object response = invokeService(args); <--- the chain of requests
that will return into error starts here
String jsonResponse = getJSONResponse(servletRequest, response);
servletResponse.getOutputStream().println(jsonResponse);
...
later in the class :
package
org.apache.tuscany.sca.implementation.java.invocation.JavaImplementationInvoker
Message invoker(Message msg){
....
Object ret;
if (payload != null && !payload.getClass().isArray()) {
ret = imethod.invoke(instance, payload);
} else {
ret = imethod.invoke(instance, (Object[])payload);
<--------------------------
}
The imethod has a reference for the method
submitQuestion which is the method invoked from the
URL
(at this point the payload variable has
the following value in the array index 0 : [{[email protected],
[email protected], subject=hello, question=test test test
test , isST=true, searchKeyword=, expertiseId=, site=test}] )
and payload has the values passed on the URL but in as Array format
instead of the Object questionDTO required by the method.
at this moment the payload comes with the following value:
[{[email protected], expertEmailId=
[email protected], subject=hello, question=test test test test ,
isST=true, searchKeyword=, expertiseId=, site=test}]
So I Think that for some reason in the middle of everything the json
object was not converted into the object type required by the method, or
it should go into the imethod.invoke(instance, payload).
At the end I got the following error:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
description The server encountered an internal error () that prevented it
from fulfilling this request.
