The lwjgl.jar does not appear to be in your compiler's classpath.

I advise getting an IDE to do this rather than the commandline. Try Eclipse (www.eclipse.org)

Cas :)

where, exactly, is the classpath?  i read the FAQ and it said to put the jar in the lib\ext folder, but jdk 1.5 doesn't have that folder.  so i just put the jar in the lib folder, but to no avail

dom

i also tried creating the ext folder, still no luck.

about eclipse: i've used it before... it's big and unimpressive.  right now i'm just evaluating lwjgl and the whole concept of java+opengl.  until i decide i really want to use this so far impressive library, the commandline is my ide

that problem has now been resolved, i missed the jre folder.   :oops:

anyways, problems still exist.  here's what i get now

It looks like you're using some old tutorial code with a recent version of LWJGL. The Window class for example isn't available anymore.

You might want to check one of the following links to find code that actually works with recent LWJGL releases:

- http://lwjgl.org/wiki/tiki-index.php?page=Basic+Game+Framework
- http://members.rogers.com/mark.bernard/

the first link is just returning errors

as for the second - i downloaded the NeHe tutorials, unzipped tut 1

the jar didn't run by itself, so i extracted it.  i noticed there was a batch file, so i edited it to reflect my configuration....still not getting it.

__________________________________________
although you guys don't have a HUGE community, i'm still disappointed in how long it's taking me to get this running.  i'm not blaming my lack of knowledge in this area on the lwjgl team, i'm blaming my lack of success of compiling and running a simple application on the lack of resources here.  just when i thought i found the correct method, i'm informed that it's old.

how about an up to date readme?  something in the format of ->

install the dll's in *this* folder and the jar in *this* folder to play games

install the dll's in *this* folder and the jar in *this* folder to make games

use *this* command string format to compile programs

use *this* command string format to run programs
__________________________________________________
chances are, such a readme already exists... i just can't find it among older how-tos and incomplete FAQ's.

I'd really like to become a part of the community - i think you guys have a great thing going.

can someone point me in the right direction?

What problems are you getting?  Did you unzip if with the same directory structure? (I did the conversions for those tutorials, so I might be able to help here)

It is on the WiKi: http://lwjgl.org/ (was just there and it is working)

Look for the link to Installing LWJGL.

well i broke down and got Eclipse (3.0.1).

i can't get NeHe ports to run, or the basic game framework to run.

dll's are in
C:\Program Files\Java\jdk1.5.0\jre\bin

jar is in
C:\Program Files\Java\jdk1.5.0\jre\lib\ext

lwjgl added as an external jar in java build path

VM arguments in Eclipse
-Djava.library.path="C:\Program Files\Java\jdk1.5.0\jre\lib\ext"

still get

1, get the files out of the jre! - look at instructions - they have been updated.

The issues you see is because you need to make the compiler treat it as 1.5 code.

I have read in at least one source that i should put  the files in the JRE; i have read none that say not too.  However, i will take your advice.

right... and where do i put that in Eclipse?

I think :) - I am using 1.4 so...

right - you need eclipse 3.1 for 1.5 to (partially) work.
Or compile from command line...
