Java .jar未在Windows上运行

Question

I am developing using Eclipse under Fedora 15. I exported a runnable jar . It works fine in Fedora. But I can't run it on windows. I have installed a JRE. I even tried installing JDK. There are no error logs, app just didn't start.

Here's the output

Answer 1

As @a_horse_with_no_name said "open command prompt and run java -jar your.jar". If it works you have to map extension *.jar to program named "java". This is how windows works. The same mechanism is working when double click on *.txt file starts Notepad.

Since I am on linux now I cannot tell you how to map the extension to program but it is somewhere in menus of file explorer.

Answer 2

它应该是可运行的jar，因此您可以双击在Windows上运行它。

Answer 3

you may be referencing a resource using absolute path.. since you say you developed the app on Linux. you might have said new File("/etc/fstab"); .. this would fail on windows as it does not have a file system like this.

this would usually be the case.

Answer 4

There is a problem with swt dlls.

1. check if the file C:\\Users\\└ЁЄю■Ёюё.swt\\lib\\win32\\x86\\swt-gtk.dll exists
2. maybe you can't load it coz u don't have admin privileges? Then Goto Eclipse installation path, right click on eclipse.exe and select "Properites". From the eclipse.exe Properties pop-up select "Compatibility" tab and at the bottom of the tab check the following check box "Run this program as administrator" in "Previlege Level" category. This should solve the problem.
3. Sometimes simply adding dlls into lib folder helps
