我们有一个Flex-BlazeDS-Spring-JMS应用程序。问题是有时我们得到Blazeds错误：NoSuchMethodException。它无法找到Java服务。这个奇怪的问题并没有发生在所有项目中......一次通过并返回结果，第二次失败，第三次失败等等。此外，并非所有方法都失败，只有2个方法调用失败。
弹性方法：
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方法：
public PatientDataMeasurementCollectionList getPatientDataMeasurements(
PatientDataRequest request);
XML响应：

我们不确定这是Flex-BlazeDS错误还是Spring Remoting问题。如果有人可以帮助解决这个问题，那就非常感激。

我不太了解所涉及的技术（除了Java），但有些调用是否可能使用不同的类加载器？相同类型的对象，但其类由不同的类加载器加载，被认为是不兼容的，可能导致没有这样的方法错误。

感谢您的回答。但是我们已经解决了这个问题...我已经为2个服务提供了1个队列，并且它正在服务一次正确的服务并且下次没有找到该方法的错误服务...无论如何它已经解决了：）
