Flex Blazeds Java NoSuchMethodException

Question

Hi All

We have a Flex-BlazeDS-Spring-JMS application. The issue is sometimes we get a Blazeds error: NoSuchMethodException. It is not able to find the Java service. The weird issue with this it does not happen all the item...1 time it goes through and returns the result, the 2nd time it fails, 3rd time fails and so on. Also not all methods fail, only 2 method calls fail.

Flex Method:

patientModel.patientRequest.startIndex=1;
patientModel.patientRequest.numberOfItems=10;
patientModel.patientRequest.medicareId=null;
patientModel.patientRequest.dateOfBirth = DateField.stringToDate("04/21/1982","MM/DD/YYYY");
//patientModel.patientRequest.dateOfBirth = new Date();
patientModel.patientRequest.lastName="null;
patientModel.patientRequest.firstName="leo";

return service.getPatientDataMeasurements(patientModel.patientRequest);

Java Method:

public PatientDataMeasurementCollectionList getPatientDataMeasurements(
   PatientDataRequest request);

XML Response:

We are not sure if this a Flex - BlazeDS error or Spring Remoting issue. Appreciate it a lot if anyone can help on this issue.

Thanks

Answer 1

I don't know much about the technologies involved (besides Java), but is it possible that some of the invocations are using different class loaders? Objects of the same type, but whose classes are loaded by different class loaders, are considered to be incompatible and that might lead to a no such method error.

Answer 2

Thanks for your answer. But we have resolvd the issue...I had given 1 queue for 2 services and it was serving the right service one time and went to the wrong service the next time and was not able to find the method...anyway it is solved :)
