我正在尝试从 Amazon WSDl 创建自己的服务。从 wsdl 到 wsdl 2.0 到 Java 的步骤运行良好。甚至 ant 编译服务也没有错误。将服务上传到 Axis2 后，将显示所有操作。但是如果我尝试调用一个操作，我总是会得到 NullpointerException。
以下是详细信息：
Glassfish 3.1.2 with axis2 1.6.2 on Windows 7 64-Bit, Java 1.7.0_25 JDK
HTTP 调用
POST /axis2/services/SimpleQueueService/CreateQueue HTTP/1.1
Host: localhost:8080
X-Amz-Date: 20130715T220823Z
User-Agent: aws-sdk-java/1.4.7 Windows_7/6.1 Java_HotSpot(TM)_64-Bit_Server_VM/23.25-b01
Content-Type: application/x-www-form-urlencoded
Content-Length: 17
Proxy-Connection: Keep-Alive
QueueName=MyQueue
答案始终是内部服务器错误，glassfish“server.log”中出现以下错误：

我试图编译最后一个axis2-snapshot，但glassfish不接受它。（例外...）
谁能给我一些提示？
