Please Help : jME and Netbeans 6.0 problem

Hello All :slight_smile:



I have been trying to get jME set up within Netbeans 6.0 and have run into some problems which I was hoping someone could help me sort out.



I have been following the wiki instructions for setting up jME with Netbeans 5.0 (and 5.5) which I appreciate are instructions for a different Netbeans version to the one I am using however I thought that the differences wouldn’t or shouldn’t be a problem. Maybe they are?



I have followed the instructions and I have ended up with a java project called jME (built using an existing source).



When I ‘clean and build it’ I get the following output:

So from the above, I am assuming that everything is fine so far.



I have omitted the jME Physics 2 steps as right now I don’t need to use it.



Now, again following the tutorial for using the compiled cvs version of jME in my own project, I have ended up with the following project structure (see image)…







Below is my code for the HelloWorld tutorial - there are no required imports as my project cannot find the correct classes.



[pre]

/*

    package org.redboffin.gs.tutorials;



    /**

    */

    public class HelloWorld extends SimpleGame {



        public static void main(String[] args) {

            HelloWorld app = new HelloWorld(); // Create Object

            // Signal to show properties dialog

            app.setDialogBehaviour(SimpleGame.ALWAYS_SHOW_PROPS_DIALOG);

            app.start(); // Start the program

        }



        protected void simpleInitGame() {

            // Make a box

            Box b = new Box("Mybox", new Vector3f(0, 0, 0), new Vector3f(1, 1, 1));

            rootNode.attachChild(b); // Put it in the scene graph

        }

       

    }

    [/pre]

    I am obviously doing something wrong but I can't tell from the tutorials where I am going wrong.



    Can anyone help me get jME working within my project within Netbeans 6.0 and once I have got it working with your help, I'd be happy to write it up as a guide for future reference on the wiki.



    Thank you for reading this far.



    Red Boffin

You are missing all of the jME jars in your libraries. I'm not sure how you created the "jME-compile" library, but something is apparently wrong with it. Try creating a new library in the library manager, containing all of the jars in jME's target directory, and use that instead.

Hello hevee



Thank you for responding.



Can I just clarify a few things?


  1. Is the jME project itself ok?
  2. Are the jME-run libraries ok?
  3. When you say "in jME's target directory" do you literally mean the folder called 'target'? If you do, then I can't find any jars in there!



    Sorry to just reply with more questions. This is all pretty frustrating as I have followed the tutorial instructions to the letter and somethings not working.



    Thanks again
RedBoffin said:

1. Is the jME project itself ok?

Yes it is. But you'll have to build it by running the "dist all" and "dist test" targets in the ant script, just "clean" and "compile", as "clean build" seems to do for you, won't do. You can run specific targets by right-clicking the ant script ("build.xml") in your jME project.
RedBoffin said:

2. Are the jME-run libraries ok?

Yes I think so.
RedBoffin said:

3. When you say "in jME's target directory" do you literally mean the folder called 'target'? If you do, then I can't find any jars in there!

Yes, I was referring to the folder called "target". You'll find the jars after running the "dist" targets as described above.

Hello hevee



Thank you for your help. I have got HelloWorld working in the sense that the required imports are found and the class compiles.



When I run it however, I get the SEVERE: Exception in game loop

java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException



message which has a fix in another thread on this forum - although that fix doesn't work for me - sadly.



Again, thank you for helping me get this far.

SSSSSOOOOO  CLLLOOOSSEEE :slight_smile:



you just need to tell the JVM where the native libraries are.



in NetBeans 5.5 you right click on the project -> select properties -> click run -> Under VM options type

-Djava.library.path="path_to_jME/jme/lib"

Thanks for trying to help me basixs.



My path to the native libraries folder is C:Program FilesJavaJMonkey Engine StuffJME_CVSjmelib



so I add the following into the VM run options: -Dpath.library.path=“C:Program FilesJavaJMonkey Engine StuffJME_CVSjmelib”



and I get the ‘no lwjgl in java.library.path’ error… yet it’s there in the lib folder… a sweet little teasing jar file…



So close… and yet soooooooo faaaaaaaaaaaaaaaaaaaaar  :’(

RedBoffin said:

and I get the 'no lwjgl in java.library.path' error... yet it's there in the lib folder... a sweet little teasing jar file...

java.library.path refers to the path for native binary libraries, not java class libraries. So depending on your os, you'll need liblwjgl.so, liblwjgl.jnilib or lwjgl.dll in the place you specified, not lwjgl.jar.

Thank you for clarifying that hevee



The lwjgl.dll (windows xp) file is there as well… teasing me… winking at me… but refusing to come out to play…

RedBoffin said:

Sorry for not spotting that earlier, that should read "-Djava.library.path", not "-Dpath.library.path"

Thanks hevee



It was just a typo on my part - the actual string I am using is -Djava.library.path="C:Program FilesJavaJMonkey Engine StuffJME_CVSjmelib"



Sorry for wasting your time on a mere typo in the message.

Did you setup the Libraries correctly (Runtime and compile) and then add them to your Project?
