Why does every passing parameters are empty ah ?
------ Solution ---------------------------------------- ----
new EndpointReference where the address should be without ? wsdl , and you then try to remove
------ For reference only ------------ ---------------------------
ah, I had to use axis1.4 can also pass a parameter of type String , and now nothing can not pass the
------ For reference only ----------------------------------- ----
how no one to speak it ?
------ For reference only -------------------------------------- -
(@ WebParam (name = "i") int i, @ WebParam (name = "j") int j)
axis2 service call java6 released when the method parameter annotation @ WebParam need to remove .
directly above sentence deleted or commented out. And then re-released under the call on OK

your original method parameters that the service class parameters gave comments. Is to give xfire call . If the method parameter annotation @ WebParam
removed. xfire will appear parameter is empty .

there are kinds of way is for species called.

The reason may be xfire than axis2 wsdl document specification requirements in multi- parameter piece something . I did not specifically look at in depth . To use CXF company behind it. Good luck !
------ For reference only -------------------------------------- -
no way you solve ? ?

------ For reference only ---------------------------------- -----
call.addParameter ("xmlStr", XMLType.XSD_STRING, ParameterMode.IN);
call.setReturnType (XMLType.XSD_STRING);

I resolved, before calling together these two lines of code , meaning that you want to pass parameters to develop , as well as return type of the result . .
------ For reference only -------------------------------------- -


This is your axis1.4 version of it . axis2 seem insurmountable. I have encountered this problem.
------ For reference only -------------------------------------- -
I solved this problem . AXIS2 call CXF server method must be coupled into the reference parameter namespace as follows:

	@WebMethod	
  	public String operatorONUPort(
  			@WebParam(name="inparam",mode=WebParam.Mode.IN,targetNamespace="http://XXXXX/")
                  String inparam){
  		logger.info("PON业务方法开始，输入参数："+inparam);

------ For reference only ---------------------------------- -----
this problem has troubled me for two days , and finally was I tried out. I hope for your help ! ! !
