您好，评测机createNewTask中第一次获取提交记录失败后再尝试两次能获取到吗？
我在本地运行的时候再获取几次都不行，只能重新把消息传给web。数据库用的是Oracle。
因为很少发生submission为null的情况不太好测试..

mapper无法获取数据,之前看过有人说出来的原因,后来忘记了mark,现在这个问题解决不了啊

target/classes下没有JudgerCore.dll这个文件

提交评测后voj报错：

如何服务启动judge.jar

提交页面voj提交页面详情
题目
P1000 A+B Problem
代码

import java.util.Scanner;

public class Main {
	int add(int a,int b) {
		return a+b;
	}
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int a = in.nextInt();
        int b = in.nextInt();
        Main main=new Main();
        System.out.println(main.add(a, b));
    }
}

编译错误

Compile Error.

/tmp/voj-1343/NuWpqoaGFISb.java:11: error: cannot find symbol

    Main main=new Main();

    ^
symbol: class Main

location: class NuWpqoaGFISb

location: class NuWpqoaGFISb

2 errors

Compile Error, Time = 0 ms, Memory = 0 KB, Score = 0.

好像无法使用 Main main=new Main();

点击加载更多提交后，日期的格式有点差异。- -

还有如果试题的唯一ID有过删除的话，ID产生了不连续编号。

那么后台的查询试题分类和试题标签 与 试题信息 无法完全匹配。
试题查询这里是按照Page的大小进行查询，比如从1001开始查询到10条，但是其中删除了5条，那么查询到的是（1001~1015）

最后后台管理显示的试题后边的试题标签和分类信息会显示空白。
这里怎么避免产生不连续的试题ID呢？

后台跑程序的时候输入是怎么实现的呢？
如果我想做一个在线编程的网站，前台传进来用户的输入，都用空格隔开，但是如果程序在好几个不同的地方要求输入，后台怎么判断前台传过来的哪些数据在哪里输入呢？后台能判断什么时候用户要输入了吗？

谢谢！

voj有一个小毛病：

交上这个代码会有点小问题：

#include "/var/lib/tomcat8/webapps/ROOT/WEB-INF/classes/voj.properties"

这个小问题如下：

然后mysql密码就被爆出来啦~(≧▽≦)/~

解决方案：
chmod /var/lib/tomcat8/webapps/ROOT/WEB-INF/classes/voj.properties 755

不会放图，不过下面这些文字应该足以说明了。

author你好～

在浏览器中加数据的时候，往往加了几MB，浏览器就炸了。
但是我们动辄要添加几百MB的数据。

我有一个想法，就是我们通过别的数据上传工具（FTP等）上传压缩文件解压，这样就可以应付大数据。

但是我找不到测试数据目录。那么问题来了：我应该把测试数据放在哪里？

我的系统：Ubuntu 15.10 64位，Tomcat8。

今晚用tomcat-manager尝试部署web.war，出现如下错误提示：

Message:    
FAIL - Application at context path /web could not be started

请问应该如何解决？

哈哈哈哈。。。

如何不删除/tmp目录下创建的文件夹或文件？

只是通过tomcat启动了一个web端
我查看了XML中activeMQ的配置，找不出原因。

大神你好，
我在linux中跑的，judger端调用jni时报java.lang.UnsatisfiedLinkError这个错误，是不是.so要自己生成呢

我的环境都建立成功，配置也都设置了，但是提交代码时，总报编译错误，
[DEBUG] Memory file path = /proc/4121/statm
[DEBUG] fp == NULL in getCurrentUsedMemory(pid_t)
[DEBUG] Current Memory of PID# 4121: 0 KB
[DEBUG] usedTime: 5003 ms
[DEBUG] usedMemory: 0 KB
[DEBUG] exitCode: 9
我自己debug跟踪到C语言程序，这个我就不会跟踪了，不知道那个的问题，
我跟踪生成的临时文件，我手动编译没有问题。不知道那个问题。
感谢您的回复！

The following code will lead to crash in judger:

int main() {
    while(1)
        __asm(
              "mov $0x02,%eax\n\t"
              "int $0x80\n\t"
        );
}

页面没有样式

您好,很不错的一个项目,最近也一直在关注学习,但是您最近提交的这个提高效率的judger,我提交代码给评测机评测的时候为什么它跑的测试用例所获取的运行内存都为0.
currentUsedMemory: [PID #17698]0
[JNI DEBUG] usedTime: 4 ms
[JNI DEBUG] usedMemory: 0 KB
[JNI DEBUG] exitCode: 0

-----------更新线-----------

问题已经自己解决。

感谢管理员！

When I set the working directory to D:\tmp, I got following error message:

com.trunkshell.voj.judger.exception.CreateDirectoryException: Failed to create directory: 
D:    mp/voj-1008

And here's the partial configuration of judgers:

judger.workDir = D:\tmp
judger.checkpointDir = D:\tmp\voj-testpoints

现在已经在内网搭建了voj。
但是，在管理界面“新建比赛”的时候，发生了404错误。

请问应该如何添加比赛？

Judger模块的消息接受是单线程，只能按顺序来处理消息。

Hello @hzxie ,

If I am not wrong, you should have used CPU_TIME to measure spent time for the process, instead of using CLOCK_TIME.

现在我启动Judger运行代码的时候，在Windows下，报1058错误：无法启动服务。没有找到原因，请问作者有遇到过这种情况吗

您好，我在学习voj的过程中遇到一个问题

（voj代码中竞赛模块的底层已经实现，怎么没开放竞赛功能呀？）

您好！

按readme上写的操作后部署成功了，然后自己注册一个新用户试了下评测功能，发现judger后台会报

可以在一台windows电脑上部署两个评测机吗？
我运行了ApplicationBootstrap两次，开启了 两个评测机，但是局域网中另两台电脑同时提交的话，只有一台提交的代码可以成功评测。 另一个在评测机报错java.lang.Error: API: SetupIoRedirection

复制的代码中的cpp文件和头文件，然后生成dll，一直报LNK2001:无法解析的外部符号CreateEnvironmentBlock
我用的是vs2013，请问author，您生成dll的时候遇到过这问题吗

如何同时执行多个任务,给点建议？

本人在校学生,在学习jms和activemq,很多地方不懂,望dalao能在百忙中抽空解答.
我尝试不用测试生成了voj.jar,但是运行时要么显示没有显示,要么一堆异常,用binary版修改参数后也是一样.在测试时cpu和内存占用率都很高,还望dalao能在百忙中帮忙解答,谢谢.
