unable to install - version mismatch?

CM · Post by CM » Thu 21. Aug 2008, 10:14

Hi,

made a download and followed the "Getting Started" instruction. (System: Ubuntu 7.10, java version 1.6)

trying to do

Code: Select all

$ javac de/jreality/tutorial/*.java

gives

Code: Select all

<snip>
;
                             ^^^^^^^^^^^^^
de/jreality/tutorial/TextureExample.java:86: error: Texture2D cannot be resolved
        tex.setApplyMode(Texture2D.GL_MODULATE);
                         ^^^^^^^^^
de/jreality/tutorial/TextureExample.java:88: error: ViewerApp cannot be resolved
        ViewerApp.display(sgc);
        ^^^^^^^^^
367 problems (367 errors)

with

Code: Select all

$ java jReality.jar

I merely get

Code: Select all

Exception in thread "main" java.lang.NoClassDefFoundError: jReality/jar

Guess something is plain wrong on my side. A java version mismatch? Does the version need to be exactly 1.5, not >=1.5? In this case: Where do I get 1.5 for my system?
Or is it possible that I overlooked something else? Any hints?

TIA
Chris

Hi,

I have just updated the getting started section, please follow the instructions there and let me know if there are problems. The problem you mentioned should be fixed. Java could not find the jReality classes, which need to be added to the classpath.

I have also updated the Download section, please use the latest jReality.jar and jReality-tutorial.zip.

Good luck,

Steffen.

Thanks!

Well, you probably realized that I have no idea whatsoever with Java. So all I can provide you with is the info that after running

Code: Select all

$ javac -cp ../jReality.jar:../lib/jtem-beans.jar de/jreality/tutorial/*/*.java

I now get 65 warningsg, no error.

And can you run the examples?

Yes, although trying to import a povray file does not work and opening a 'bean shell' gives

Do I need to link additional files in?

Yes, add all files in the jRreality-3rd-party.zip to the classpath... You can also set an environment variable CLASSPATH instead of passing it all via command line.

I guess the povray import problem is independent of the classpath, please give more details. However, the reader supports only a very small subset as far as I know.
