lauch4j你好世界计划 [英] lauch4j hello world program

问题描述

我创建了一个"hello world" java程序，并使用lauch4j将可执行的jar转换为.exe文件.当我尝试在cmd中运行它时，什么都没打印出来.我也尝试在launch4j中运行它.日志指示:执行中:C:\ Documents and Settings \ cnbq84 \ Desktop \ helloworld.exe.但是仍然没有显示"hello world".

I created a "hello world" java program and use lauch4j to convert executable jar to .exe file. When I tried to run it in cmd, but nothing printed out. I also tried to run it in launch4j. Log indicates: Executing: C:\Documents and Settings\cnbq84\Desktop\helloworld.exe. But still no "hello world" is displayed.

如何显示"Hello World"消息?

How to display the "Hello World" msg?

推荐答案

您可能未处于控制台模式.

You may not be in console mode.

来自 http://launch4j.sourceforge.net/docs.html

要在控制台模式下包装jar，请使用 launch4jc.exe并指定 配置文件. launch4jc.exe config.xml

To wrap a jar in console mode use launch4jc.exe and specify the configuration file. launch4jc.exe config.xml
