Java program to package JRE and make installation package
Java Desktop program can only be run in eclipse after the operation is not possible, but also need to copy the program to other computers to run, so you need to make the other computer can run files, of course, on the computer installed with the JDK only need to export the program as a jar file can be run, But instead of installing the JDK on the computer where the Java program is being developed, there is no such environment on other people's computers, so it is also necessary to package the Java-ready environment in the program so that it can be run without the user installing the JDK.
The process of making an executable file
first, after the program is written, export the jar file.
1. Right-click the project file in Eclipse and select Export
2. Select Export as runnable jar file, then next
3. Select the main portal window of the application, save the path of the jar, export the file, select the first second can, they all contain the library files required by the program, the first benefit of the export is to prevent the program from being recompiled, the second can retain the original file structure, and then finish
4. Locate the exported JAR file,
second, run the file with the Java command
1. Open a Command Prompt window and locate the JAR directory
2. Run the jar file using the Java–jar command
3. Enter to see the program run up
4. But the program does not have pictures, look closely at the size of the jar package can guess no resource files, with WinRAR view jar internal structure found without these resources
third, the resource files required by the program are copied to the same directory of the Jar1. Locate the file resource that is required in project except SRC
2. Copy these file resources to the same directory as the JAR package
3. Run the jar file again to find that it contains files such as pictures
d. Convert the jar file to an EXE file that can be run directly by double-clicking
1. Converting a jar file to an EXE file there is a good software called Jar2exe, official:
HTTP://WWW.REGEXLAB.COM/ZH/JAR2EXE/FREE.HTM[/U]
We download the green version

7. Ignore all options and go directly to the next step
8. You do not need to add a dependent jar package, the next step
9. Set the output path file name, you can also set the EXE file icon, click Next
10. If you have an environment variable configured on your computer, and you do not need to copy the program to another computer, you can click Done directly.
11. If you need to replicate to other computers that do not have a JRE environment, then you must first keep the above window and copy the JRE to the same directory as the jar file just now.
The path to the JRE is the path where you install the JDK, and mine is C:\Program files\java\jre1.6.0_07.
12. Then select the parameter Configuration button for the window, and configure the path of the JRE to the relative path of the jar package.
Select the JRE Settings tab, select Profile specify ', select relative path, then edit
Locate the Jvm.dll in the JRE and then make sure that the application is ready.
At this point in the folder will be more than a config file, this file can be EXE file reference to the same directory of the JRE environment,
13. After the conversion is complete the jar can be deleted, double-click EXE to run, to see the effect:
14. In order to verify that this program can run on a computer that does not have a JDK installed, we test that opening the Win7 flagship version of Xpmode,xpmode is an XP virtual machine for Win7, which is a complete XP system that copies files to XP,
15. Double-click Kejian.exe to see the effect:
16. Although the program has been completed, but we can not give users a folder, and then let the user copy, copy and then double-click EXE to run the program, so we will also make the installation package.
Five, the Production program installation package
