all java files in one

[richy19]

hi for college i have had to make various applications
of which most of them have used some kind of pictures
and to do this i have allways had to have the images in a seperate folder
i wanted to know (if possible) how to put the images and other files into the one file (.jar)
also what DataBase does java use? can it use mysql or does java have its own database?

Yes you can include images and other non-java files in your jar, there's some info on creating jar files here: http://www.cs.princeton.edu/introcs/...n/jar/jar.html

As for the databases, Java can connect to all the major databases; MySQL, Oracle, DB2, SQL Server, etc.. For more information search for JDBC (Java DataBase Connectivity).

thanks it looks like it will do the trick
i was wondering if theres an easyer way of doing it with netbeans? other than creating the manifest and using cmd promp

[Mblaster]

Not used Netbeans before, but you can do it though the GUI in Eclipse so I'd imagine there's a way to export to jar in Netbeans too, Google is your friend...

Just getting to grips with Eclipse myself for coding - really nice!

just thought i would say how i managed to (finally) do this

Adding a Package for the Image

When you use images or other resources in an application, typically you create a separate Java package for the resources. On your local filesystem, a package corresponds with a folder.
To create a package for the image:
In the Projects window, right-click the org.me.myimageapp node and choose New > Java Package.



In the New Package wizard, add .resources to org.me.myimageapp so that the new package is called org.me.myimageapp.resources.
Click Finish.
In the Projects window, you should see the image appear within the org.me.myimageapp.resources package.

then you insert the images into the new folder that has been created (which should be in the same folder as your .java file)

and use this to "get" the image

button.setIcon(new ImageIcon(this.getClass().getResource("resources/myIcon.gif")));

hm ok so that works with images but not with files
i have a midi file that when i try to do that it says it wants a java.io.file and it has a url
i have tryed to convert it but it wont let me

[Mblaster]

If it wants a java.io.File object then create one with: new File("path_string"), but not sure what 'it' is that requires the file object. The getResource() method returns a java.net.URL object, which works for creating an ImageIcon, but may not work for some other kind of file access.

Also, creating a package like that for the resources seems pretty odd to me (even though a package is just a folder), since your resources will be located in the source folder...
