Overview: i am using springsourcetool (similar to eclipse) as the development IDE. Glassfish as the application server. the web service is ChequeProcessingService, i generated the .aar file and deployed it under axis2 web project of glassfish. the client side code is generated using axis2 code generator tool, it is simply calling the web service method 'chequeCertification' that has a javabean request parameter and returns another javabean response object.

Axis2 version that am using is 1.6.2 with JDK 1.7
我使用的 Axis2 版本是 1.6.2 和 JDK 1.7
Kindly advice from where may come this problem.

The real problem is this NullPointerException in your server:
真正的问题是服务器中的 NullPointerException：
Caused by: java.lang.NullPointerException
at org.ws.server.implementation.ChequeProcessingService.chequeCertification
(ChequeProcessingService.java:18)
This is probably in some code that you wrote, so it's not possible to say exactly what the problem is.
这可能在您编写的某些代码中，因此无法准确说出问题所在。
The client error is probably just a reaction to the bad response returned from the server when the server threw an exception. You should consider adding some logic to catch AxisFaults that are thrown when you call a web service, so that you could for example print a more suitable error message.
客户端错误可能只是对服务器抛出异常时服务器返回的错误响应的反应。您应该考虑添加一些逻辑来捕获调用 Web 服务时抛出的 AxisFaults，以便您可以例如打印更合适的错误消息。
