Java packaged as EXE and portable

Questions and ideas

People may encounter this situation, their hard-working Java program, but on someone else's computer can not run, there may be several reasons for this:

• Your own programs rely on external jar packages
• The picture cannot be displayed after the program has been shot into a jar package
• The other computer does not have a Java environment

But isn't Java a good portability? Is there a way to do a Java program that can be executed everywhere? There are various methods on the Internet, but they are relatively general, or can not be used in some cases, here is a practical experience of my own as an example for everyone to reference.

The core ideas are as follows:

• Make your own program into a jar package
• Turn the jar package into an EXE file while establishing a jar package dependency, and a relative link to the JRE environment
• Create the Installer

Required Software:

• Of course eclipse is essential (or myeclipse)
• EXE4J (turn jar into exe) Download: http://www.onlinedown.net/soft/15755.htm
• Inno Setup (build installer) Download: Http://rj.baidu.com/soft/detail/15918.html?ald
