External librairie isn't included into classpath

Hi,

My mod need external jar files to work,

I added it, to my mod folder.

Console say :

[23:57:51 INFO]: Client> [23:57:51] [Client thread/INFO] [FML]: FML has found a non-mod file commons-codec-1.6.jar in your mods directory. It will now be injected into your classpath. This could severe stability issues, it should be removed if possible.

But next, when I print the classpath, I get this :

So they aren't into the classpath ! *_*

Is this a bug ? Anyone can help me ?

Thanks

The files are loaded to your mods directory. FML uses a custom classloader to load these files. You do not need them in the classpath, they're perfectly fine in the mods folder.

No it doesn't work, I have a NoClassDefFound error.
