请问os400下Java代理使用axis调用webservice服务无法运行异常

请教os400下Java代理使用axis调用webservice服务无法运行错误
我写了一个使用axis调用webservice服务的java代理，在windows系统下都可以成功运行，可是当要部署到正式的os400环境时就会报错。另外我把axis jar包放在正式环境os400上的/QIBM/ProdData/LOTUS/DOMINO703/JVM/LIB/EXT目录下，不知道对不对？
请大家帮帮忙，我都块崩溃了，这个问题困扰我一个多月了。

java代理如下：

Java code

import lotus.domino.*;
//引用axis需要的类
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class JavaAgent extends AgentBase {
    public void NotesMain() {
        Session session = null;
        AgentContext agentContext = null;
        Service service = null;
        Call call = null;
        String result = null;
                
        try {
            session = getSession();
            agentContext = session.getAgentContext();    

            //用axis方式初始化webservice对象
            service = new Service();
            call = (Call) service.createCall();
            call.setTargetEndpointAddress("http://127.0.0.1/hyzqoa/indiwscenter.nsf/wsCheckUser22");
            call.setOperationName("wsCheckUser22");            
            //访问webservice，并返回数据
            result = (String) call.invoke(new Object[]{});
            System.out.println(result);
            
        } catch(Exception e) {            
            e.printStackTrace();            
        }
    }       
}

错误信息如下：
