标题: LR java vuser 空指针异常 [打印本页] 作者: zbzbzb022 时间: 2010-6-28 16:29 标题: LR java vuser 空指针异常 我用java写了一个远程调用的程序，通过url携带参数的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了。我把编译好的包含绝对路径的Class文件放到虚拟用户目录下，有三个需要的第三方jar包，我也同样放到了虚拟用户的目录下了。使用如下代码进行调用。
import lrapi.lr;
import com.lt.test.*;
import com.lt.testauth.*;
public class Actions
{
public int init() throws Throwable {
return 0;
}//end of init
public int action() throws Throwable {
lr.rendezvous("申请任务！");
new AuthUtil().main((String[])null);
return 0;
}//end of action
public int end() throws Throwable {
return 0;
}//end of end
}
可是为什么会报出空指针异常呢？异常信息如下：
Virtual User Script started
Starting action vuser_init.
Ending action vuser_init.
Running Vuser...
Starting iteration 1.
Starting action Actions.
Rendezvous 申请任务！

大家帮忙看看啊，我是新手啊，什么都不懂啊！作者: yinxiaodan 时间: 2010-7-8 20:36
是不是少了什么外部文件没有拷贝到脚本目录下作者: 泊涯 时间: 2010-7-9 19:28
是不是有JAR 包没有加载进去
或者你系统环境变量没设置对作者: msnshow 时间: 2010-7-16 20:48
初始化就失败了，应该是少了需要的包作者: iewgku 时间: 2010-10-9 10:50
请问楼主的问题解决了吗?我也碰到这个问题.不知从何下手.在其它开发工具中都能成功运行.但是在LR中就报错了.作者: lilye974 时间: 2012-3-2 16:47
同问，现在到底解决了没有。作者: 随风而动 时间: 2012-6-13 12:45
有解决办法没啊？？？作者: 金小言 时间: 2014-6-6 16:49
重新导入jar包以及Class文件作者: yetties2005 时间: 2014-9-29 17:17
JAR包要放在项目中，运行LoadRunner前要先编译作者: Frankwangyifang 时间: 2014-11-28 16:54
