Question

我正在尝试从Amazon WSDl创建自己的服务。从wsdl到wsdl 2.0到Java的步骤很好。即使是ant也可以毫无错误地编译服务。将服务上载到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-呼叫

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

答案总是内部服务器错误，并在glassfish“server.log”中出现以下错误：

我尝试编译最后一个axis2-snapshot，但是glassfish不接受它。（例外...）

有人能给我一些提示吗？

Answer 1

似乎SQS WSDL上的所有远程调用都将text / xml作为输入，而不是application / x-www-url-encoded。假设我正在查看与您相同的WSDL。

Answer 2

在我们的示例中，由于部署中缺少了jar，因此它抛出了相同的异常。

axis
jaxrpc
saaj
wsdl4j-1.5.1
commons-discovery-0.2

我们正在使用轴1.4

自己的服务总是导致Axis2中的NullPointerException
