Basic startup problem...

[plonkman]

Hi all.. first post here..

I`ve used ODE a fair bit with C++ and had a lot fo fun with it.

I`m currently trying to convert some of my old dodgy demos across into java for a uni project.

I`ve downloaded the latest natives and .jar and have no problems compiling the code, but when I try to execute the program I get this error...

java.lang.UnsatisfiedLinkError: dWorldCreate
     at org.odejava.ode.OdeJNI.dWorldCreate(Native Method)
     at org.odejava.ode.Ode.dWorldCreate(Ode.java:526)
     at org.odejava.World.<init>(World.java:112)
     at MainGame.initialise(MainGame.java:124)
     at MainGame.main(MainGame.java:63)

There`s obviously some problem with runtime linking to the ODE native...

I`m using the opengl Java bindings no problem and they work a treat.

Has anyone else encountered this problem?

Cheers.

Yes put odejava.dll in your classpath then call

System.loadLibrary("odejava");

Before you do any odejava stuff


When that  works youll also need  org.apache.log4j.Logger

Get it here..

thanks.

i`d got to the log4j stuff already but your post helped a great deal.

cheers.

hi there
i am geting the same dWorldCreate() error

and got the log4j and it i am still geting the same error

can u please help thanks
here is the run time exception

Exception in thread "main" java.lang.UnsatisfiedLinkError: dWorldCreate
        at org.odejava.ode.OdeJNI.dWorldCreate(Native Method)
        at org.odejava.ode.Ode.dWorldCreate(Ode.java:526)

Press any key to continue . . .

and also

System.loadLibrary("odejava");

?

[m_ali_alex]

yes
as a matter of fact am trying to run the example on the tutorial
just for the record i am using windows xp
thanks


here is its header....

import javax.vecmath.*;

import org.odejava.*;
import org.odejava.collision.*;
import org.odejava.ode.Ode;

public class BasicOdejavaExample {

   private World world;
   private Space space;
   private JavaCollision collision;
   public static final Vector3f gravity = new Vector3f(0f,-9.82f,0f);

   // Loads the Odejava library (optional but will though an error
   // sooner if it can't be found.
   static {
      System.loadLibrary("odejava");
   }


and does have in it self the      System.loadLibrary("odejava");

here is also a screen shot of the classpath
incase if u need to see it
thanks

mmh I just looked at my own source code and I'm only doing this (in the constructor of my main class)

1   2

Odejava.getInstance();         World world = new World();

hi there folk
i guess i figured how to make it work
here is a snap shot of the code that need to be corrected


**************************************************

import javax.vecmath.*;

import org.odejava.*;
import org.odejava.collision.*;
import org.odejava.ode.Ode;

public class BasicOdejavaExample {

   private World world;
   private Space space;
   private JavaCollision collision;
   public static final Vector3f gravity = new Vector3f(0f,-9.82f,0f);

   // Loads the Odejava library (optional but will though an error
   // sooner if it can't be found.
   static {
      System.loadLibrary("odejava");
      Odejava.getInstance();

   }

// add the the Odejava.getInstance () after the System.loadLibrary("odejava"); statement



thanks and good luck
