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!

Vuser Terminated. 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. 大家帮忙看看啊,我是新手啊,什么都不懂啊! 是不是少了什么外部文件没有拷贝到脚本目录下 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 初始化就失败了,应该是少了需要的包 同问,现在到底解决了没有。 有解决办法没啊??? 重新导入jar包以及Class文件 JAR包要放在项目中,运行LoadRunner前要先编译 iewgku 发表于 2010-10-9 10:50
