lr执行java Vuser脚本的nullPointException

cflong_a

我用java写了一个远程调用的程序，通过socket方式访问远程服务器，以获取服务器的响应，在eclipse下编译通过也能正常访问远程服务器并能得到服务器的响应。
我把编译好的包含绝对路径的Class文件和第三方jar包放到虚拟用户的脚本目录下，用测试类测过这样的方式可以调用成功，再使用如下代码调用就出现nullpointexception：

import lrapi.lr;
//import d_20131001.*;
import org.engineClient.*;
public class Actions{
    public int init() throws Throwable {
        return 0;
    }//end of init
    public int action() throws Throwable {
        //HelloWorld.main((String[])null);
        Demo.main((String[])null);
        return 0;
    }//end of action
    public int end() throws Throwable {
        return 0;
    }//end of end
}

对应的java代码：
package org.engineClient;
import org.apache.log4j.Logger;
import org.hibernate.Transaction;
import com.amarsoft.core.object.ResultObject;
import com.amarsoft.socket.SocketObject;

15 public class Trade {
16    Logger logger = Logger.getLogger(Trade.class);
17    private static String sIP = "localhost";
18    private static int iPORT = 7000;
19    private static String sSAVEPATH = "";
20    private static boolean bUseSSL = false;
21    private static int sTIMEOUT = 180;
    ......
异常信息如下：
