java调用webservice接口,并解析返回参数问题

// 确定传参格式以及赋值
String reqXml = "<createAppParam>\n" +
                    "<serviceUserName>auth</serviceUserName>\n" +

                    "<resNum>1000</resNum>\n" +
                    "<operationCode>"+operationCode+"</operationCode>\n" +
                    "<functionCode>668801</functionCode>\n" +
                    "<authMode>"+mode+"</authMode>\n" +
                    "<applyReason>"+sendApplyParam.getCerReason()+"</applyReason>\n" +
                    "<userTimes>9999</userTimes>\n" +
                    "<duration>"+sendApplyParam.getExpire()+"</duration>\n" +
                    "<userIP>"+ip+"</userIP>\n" +
                    "<selectedApprover>"+sendApplyParam.getApproverId()+"</selectedApprover>\n" +
                    "<workOrderID>999999</workOrderID>\n" +

//方法调用
