问题描述

多线程调用Axis客户端异常问题请教

相同版本程序大部分时间可以正常运行（一直为bug不规律出现烦恼，提升并发线程数量不会增加其出现频率，至今出现2次），

偶尔启动运行抛出以下异常（不存在参数个数不匹配问题)。下附异常信息与代码片段：

run（）方法中部分代码：
call = (Call) soapService.createCall();//soapService为单例，因为不规律报错，无法证实是此原因

call.setTargetEndpointAddress(soapService.getUrl());
call.setOperationName(new QName(soapService.getTargetObjectURI(),soapService.getMethodName()));
call.addParameter(new QName("http://***********/********/exchange", "parameters"), new QName

("http://***********/********/exchange", "parameters"), String.class, ParameterMode.IN);//

    call.setReturnType(XMLType.XSD_STRING);

response = (String) call.invoke(new Object[] { crmReq });
