This is the error when i execute the 3DS Koader program from xith.com...what should i do to overcome this problem...

[kevglass]

Make sure the "model" directory with the "character.3ds" appears in your classpath.

sorry...i dun clear about the classpath...can you make it more detail....
thanks lot

[kevglass]

How are you running the TDSTest ? i.e. what command line are you using?

Kev

[jOshfLY]

oh...im using NetBeans-IDE...is it ok for it?

[kevglass]

Yeah, thats fine, to get it to run you must have added xith-3ds.jar to the classpath. Where you did that you need to add the directory that contains the "model" directory.

So if you put all the files in:

c:\code\

So that this would exist:

c:\code\model\character.3ds

You need to make sure "c:\code" is in your classpath.

Kev

[AndersDahlberg]

Or, I'm not trying to be an *** here..., try to study http://java.sun.com/tutorial and learn some basics, how the classpath works, how to compile and run java programs first - It's a lot easier to understand what we're trying to say here then!

[jOshfLY]

The .3ds i put in here...

c:\xith-3ds\model\character.3ds

is it right?? but still can not locate the character.3ds....headache

[jOshfLY]

Sorry...i still can not do it...please help me out...thanks a lot

[kevglass]

Is character.3ds actually in the model directory?

Kev

Games published by our own members! Check 'em out!

[jOshfLY]

yupe, the character.3ds is in the model folder...

or do i need to modify the code?? the code originally is like this

model = new TDSLoader().load("Model/character.3ds",true);

[kevglass]

na, should be fine. If you put all the files in the c:\xith-3ds\ directory then you need to modify the classpath to include it.

In Netbeans, you need to "mount" the c:\xith-3ds\ directory. Right click on the filesystems icon and mount the directory.

Kev

[jOshfLY]

no, can not...when i mounted the files i got the list on hte Explorer [Filesystem] like this :-

-c:\xith-3ds
 -model (folder)
 -org (folder)
 -TDSTezst
 -jogl.jar
 -lwjgl.jar
 -test.bat
 -vecmath.jar
 -xith-3ds.jar
 -with_utilities

[kevglass]

Thats right, you should be able to run it then..

[jOshfLY]

do you know this .jar?? where i can get it??

import display.DisplayOptions;

[kevglass]

Um, have you just context switched or something? DisplayOptions is nothing to do with the 3DS loader, I believe its part of JavaCoolDude's demo stuff?

Kev

[jOshfLY]

oh...yaa..is JavaCoolDude's demo..wahh you are smart  

i get error on that particular part....so, im looking for the .jar

you know how to get it??

[Java Cool Dude]

do you know this .jar?? where i can get it??

import display.DisplayOptions;

Linky linky link link

[jOshfLY]

Oh..very thank you kevglass and Java Cool Dude...cool! horayyyy~~~especially kevglass...im very appreciate you spent your time here with me...

Java Cool Dude can you plz...have a look for my problem...please

[Java Cool Dude]

Yes I ran into the same problem than you and I came up with solution; suicide....
j/k here's what I did

1   2   3   4   5   6   7   8   9   10   11

BranchGroup  holdModels  = new BranchGroup();     ClassLoader  fileLoader  = RippleFactory.class.getClassLoader();     InputStream  fileStream  = fileLoader.getResourceAsStream("Data/pond.3ds");     try{       if(fileStream == null)         fileStream  = new java.io.FileInputStream("Data/pond.3ds");       holdModels = new TDSLoader().load("",fileStream, false);     }     catch(Exception e){}

Of coarse you need to make the due modifications as in not every class out there is named RipleFactory

[jOshfLY]

er...in my case...which part of my program need to modifiy???

[jOshfLY]

JavaCoolDude's Demo the WaterSimulation can not execute...

java.lang.Error: Cannot load image Data/Water.png

please help

[aNt]

fun fun fun

[Java Cool Dude]

/me stabs self in the face with a soldering iron

[jOshfLY]

hahahaa.....i don't know what happen actually...
i usually download the source code and put it on my desktop...and run the program...

or should i put the program to c: or else???

[AndersDahlberg]

http://java.sun.com/tutorial - please!  

Good luck though on your future java explorations!

With Kevin's 3ds loader I experienced the same problem - because I don't put the app's resource paths into the classpath.
Let's asume your Java application stays in a folder with a subfolder "models/", where the models as well as their textures are. In addition to the model's InputStream we've to give the "models"/ path to the loader, too, in order it can find the textures. From the three (+) possibles ways to create a TDSLoader I can only use this one:

1   2   3   4   5   6   7   8

final String pathname = "models/"; final String modelfile = "Yourmodel.3ds"; InputStream bis = FileInputStream(pathname + modelfile); TDSLoader dslader = new TDSLoader(); dslader.setGenerateMipMaps(true); TDSModel model = dslader.load(pathname, bis, true);

This way it works fine, no matter how you start the Java application: via dosbox (java -cp ..), or via double click on your App.jar, or at a friend's PC (again with emtpy CLASSPATH).

any problem in my program??

[SpuTTer]

Posting the whole program is excessive, especially not in a code block...

Based on previous posts, I'll start with the obvious, do you have a file at the path "model/character.3ds"  ?

[jOshfLY]

yes i do have...is like this

c:\xith-3ds\model\character.3ds

i even put the character.3ds here

c:\xith-3ds\character.3ds

but still can not locate the file...and one more, even if i change the file name like this

   final String pathname = "model/";  
   final String modelfile = "cube.3ds";

it still display the error message

*java.io.IOException: Not found: model/character.3ds


instead of  

*java.io.IOException: Not found: model/cube.3ds


please tell me why it still look for character.3ds only but not for cube.3ds...i tried other files but still look for chracter.3ds

thanks
josh
