I just downloaded LWJGL and for some reason the -Djava.library.path command isn't being recognized. I followed the installation tutorial for Eclipse on the LWJGL website but entering -Djava.library.path=C:\Documents and Settings\Owner\Desktop\lwjgl-1.0beta3\native\win32 in the VM arguments didn't seem to do anything. Also the step where I'm supposed to navigate to the directory where I extracted LWJGL and say:

java -cp .;res;jar\lwjgl.jar;jar\lwjgl_test.jar;jar\lwjgl_util.jar;jar\lwjgl_fmod3.jar;jar\lwjgl_devil.jar;jar\jinput.jar;
    -Djava.library.path=native\win32 org.lwjgl.test.WindowCreationTest

doesn't work either. It returns the error:

'-Djava.library.path' is not recognized as an internal or external command, operable program or batch file.

Luckily LWJGL works in my Eclipse project if I copy and paste the .dll files to the folder of my project , but I want -Djava.library.path to be recognized so I can run LWJGL programs through the command prompt and not have to copy and paste the dll files to every project. Anybody know what the problem is? I'm guessing maybe it has to do with my CLASSPATH and PATH variables, but I'm not sure. Thanks in advance and sorry if this is a dumb question.

dont know why the last one (dos prompt) doesn't work - but the first one might be because of the space in documents _ and _ settings

Use quotes around the classpath:

java -cp ".;res;jar\lwjgl.jar;jar\lwjgl_test.jar;jar\lwjgl_util.jar;jar\lwjgl_fmod3.jar;jar\lwjgl_devil.jar;jar\jinput.jar;" -Djava.library.path=native\win32 org.lwjgl.test.WindowCreationTest

the classpath isn't the problem, its the -Djava.library.path=natives\win32

I generally do -Djava.library.path="./natives/win32/" and that seems to work fine...
