Answer 1

axis好久以前用的,,差不多忘记了..!  还是帮你看看吧!顺便问下:LZ有JDK1.6的环境吗.? 

Answer 2

谢谢 我用的JDK1.5 

Answer 3

call.setUseSOAPAction(true);
  call.setSOAPActionURI(url);
去掉试试

Answer 4

空指针，
别人不了解你的程序逻辑，光凭你贴的这些代码很难找到问题的。同时贴一下你服务端queryDriver方法的代码。

Answer 5

空指针的36行是哪一行呢？真不明白，你既然用axis，何必还要写这个套路的代码？？？？
可以自动生成代码的呀。

Answer 6

我最近也在写一个webservice，用Axis
static String baseendpoint = "http://192.168.10.51:8080/smartSaleWS/services/BaseInfoWebService";


public static String DepartmentNum(String depId){
Service service = new Service();
Call call = null;
String DepartmentNum = "";
try {
call = (Call) service.createCall();
call.setOperationName(new QName(baseendpoint,"findDepartmentNum"));
call.setTargetEndpointAddress(new java.net.URL(baseendpoint));

DepartmentNum = (String)call.invoke(new Object[]{depId}); }catch(Exception ex)
{
//ex.printStackTrace();
logger.error("-->webservice出现异常");

}
return DepartmentNum;
}
这样的客户端就ok了，没LZ写的那么复杂！
顺便问一下，楼主确定调用服务端的这个方法返回的是String？

Answer 7

respXML= (String) call.invoke(new Object[] {"48019566268","2010060109253068","1","130100007184","h"});
