using Class.getResource() load resource file in Eclipse

There are many ways to load resource file in java app. What sun recommended is using Class.getResource("resource_name") or Class.getResourceAsStream("resource_name") then you will get URL and InputStream respectively. If resource_name is specified without "/", it will be prepend with Class package. So resource file must be in same place[folder structure] as the Class. What I love to do is call getResource() with "/" and put resource file at the root of package. This way i can have separate resource folder. below is in Eclipse,

1. From Package explorer right click src folder->click import
2. In import dialog, Choose General->File System ->next
3. from directory:->Browse to your resource folder.
4. to folder:-> I add "resource" as a folder name under src folder. then click "Finish".

In the code, load resource with
this.getClass().getResource("/resource/buttons1.png")
or
this.getClass().getResourceAsStream("/resource/TX_Jello2.ttf")

Lovely post, works like a charm.
Could you maybe explain the difference to the ClassLoader.getSystemResource(..) function? I could not find comprehensive help on this topic and it looks like resource loading is a very often encountered problem.

I have noticed the following problem with getRessourceAsStream(): for every call, the jar il loaded again. This can be very annoying, especially when the jar il loaded over a slow connection.

Surely the title should be using Class.getResource() load resource file in Java.... you're code isn't anything to do with the IDE

Very nice tip.

Instead of using "/resource/filename" I'd put files in my main pachage folder, and just use a class in there to call getResource().

This way we avoid conflicts with other libs!
thanks it's solve my Windows and Linux class path related issues.

Converting dat to mpeg file, to burn vcd on ubuntu

Creating vcd [from dat file] on WinXP, I use "Nero Burning Rom". It can burn dat file to vcd directly. On ubuntu, AFAIK, No burning cd software to burn dat to vcd. I use k3b but it can't burn dat file. It support only mpeg-1 and mpeg-2 format. Dat file need to convert to mpeg first. Thist post will show how I install and use vcdgear to convert dat file to mpeg file. pnix@pnix-a7n:~/progdl$ wget http://www.vcdgear.com/files/vcdgear176-040415_linux.tar.gz --04:21:14-- http://www.vcdgear.com/files/vcdgear176-040415_linux.tar.gz => `vcdgear176-040415_linux.tar.gz' Resolving www.vcdgear.com... 66.98.192.104 Connecting to www.vcdgear.com|66.98.192.104|:80... connected.
