Java program is packaged into exe

Background: Recently, an old friend who was a teacher asked me to write a small program for her. The program is very easy to implement, but I have never played the .exe application. I searched the Internet and there are several tools that can be packaged. The package was successfully packaged and used. There was an episode of system incompatibility during the period. Finally, it was replaced with 32-bit. It can run on both 32-bit and 64-bit systems. Be sure to use the created jre directory environment for packaging, because the jdk environment will not be installed on a non-developer computer.

working environment

  系统：win10  64位

  JDK：jdk1.8  64位

  开发工具：myeclipse2015

  打包工具：exe4j_windows-x64_5_1   下载地址：http://www.ej-technologies.com/download/exe4j/files.html

The program is packaged into .jar
1. Open myeclipse, select the program you want to package, right-click and select export

Click ok and
click finish, the sas.jar file will appear on the desktop

Fourth, convert jar into exe.
Create a new folder, the role of the folder is to save the generated exe file directory, in the newly created folder also create three subfolders file, res, jre

 file:文件夹是放临时文件的可以没有

 res:文件夹是放资源文件的，如图片，配置文件等也可以没有

 jre:这个是必须的，该文件中的内容可以直接把JDK安装目录下jre的内容拷贝过来即可。有了它可以不用再装java运行环境 

 上面提到我的运行环境是jdk64位，但是在这里面应该放上 jdk32位，即jdk32安装目录下的 jre文件内容，嗯，还有就是如果程序中有任何jar包应该放在SAS\jre\lib\ext文件里。

 


 将exej4下载到电脑上  如果运行界面没有出现  就在安装目录下 bin 目录中点击 exe4j
