用Eclipse打包我的项目

Question

I have a Java swing project which i need to test on other computers. I have some classes and a sqlite db which stores login information. I have some lib jars as well. The application takes information from the user and stores it in the sqlite db and then pushes data to the web. I want to package my project so that whoever uses my project has to just double click on an executable or jar.

I tried to Export to a Runnable Jar file in Eclipse but this does not give desired results. After the runnable jar is created and i run it for the first time it creates the sqlite db beside it and does not connect to the web link and send information.

How can i package my data properly? This is my folder structure -

root
--src
----default package
----rest package
----images
--lib
--file.fcl
--db.sqlite

Any time you run a program outside eclipse that changes any file within a project folder structure, the file changed is "out of sync". To bring things back in sync, right-click on the project in Package Explorer and choose "Refresh" (you can also select the project in Package Explorer and press F5).

If your code is creating the database instead of using the one that is there, it suggests to me that your database location is set for your eclipse environment but not for the general case. For a java application, you have to know (or set) the "current directory" or "current folder" -- this is a folder that is the default for file operations, and from which relative file paths are set. If your current directory is "aaa", and you open a file or database at "bbb/ccc/ddd/database.db", then the "bbb" directory must be within "aaa" or the program won't find the file.

To run your program without having to set the database location, etc., then you're probably going to want to discover the directory in which your program file is stored and set that as your current directory. This SO answer indicates how you might do that.
