WebService问题

1.报错：

 

javax.servlet.ServletException: javax.servlet.ServletException: org.apache.axis2.AxisFault: The system is attempting to engage a module that is not available: addressing
	org.apache.axis2.transport.http.AxisServlet.init(AxisServlet.java:462)

	java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
	java.lang.Thread.run(Thread.java:619)

 因为没有引入axis的modules文件夹到工程的WEB-INF目录

 

 

2.报错：

org.apache.axis2.deployment.DeploymentException: The following error occurred during schema generation: null

原因是在要通过soap协议传输的POJO对象（主要是getter/setter方法）中包含了不能序列化的对象。。因为有些属性没有办法序列化，我最后又封装了一层，这样才成功

 

3.返回对象中不能有list，要转成数组
