可用方法的NoSuchMethodException

Question

我正在使用一个开放的KM应用框架作为我的应用程序。奇怪的是，有时我会在代码中为可用的方法获取NoSuchMethodException。一旦我开始得到这个异常，它就会一直重复，直到我重新启动服务器(Jboss7)。一旦重新启动，这将工作文件，直到某个点，然后再一次，这个异常将发生，并继续发生。

有人能帮忙吗？

我的异常跟踪

我还添加了其他一些跟踪，以了解调用类和预期方法是什么。这些都是结果

19:34:10,719 INFO  [stdout] (http--192.168.1.62-8080-2) Trying to fetch method ========      create from class : interface com.openkm.ws.client.document.OKMDocument

19:34:10,719 INFO  [stdout] (http--192.168.1.62-8080-2) >>>>>>>>>.... [B

这是调用的方法端点类中的getMethods的结果。

19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2)  Method Name :: create
19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters.... java.lang.String
19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters....  com.openkm.ws.client.document.Document
19:34:10,721 INFO  [stdout] (http--192.168.1.62-8080-2) Parameters.... [B

正如我们所看到的，调用签名是

create(String, com.openkm.ws.client.document.Document, byteArray)

目标类也有一个具有相同签名的方法，但有时我仍然会得到这个NoSucnMethodException，就像前面说的那样，一旦它来了，它就会永远地出现，直到我重新启动服务器。

任何帮助..。

com.openkm.ws.client.document.Document是一个接口。我怀疑运行时部署中缺少实现。
