How can I add the classpath ?

[paulthelazy]

I have added the CLASSPATH variable in the ./profile (I use Linux). But the javac don't compile *.java files. I haven't programm java and a newbie in Linux. Please tell me step by step.
PS Sorry for my English. And can I write here German ?

What do you want to compile? Does it work when you pass the classpath directly to javac (javac -classpath jReality.jar:bla1.jar:bla2.jar *.java)? Which java version do you use? Which linux?

Maybe you should use eclipse?

I want to compile the tutorial
It is do:
* In Directory ~/jReality:

Code: Select all

+jReality.jar
+antlr.jar
+bsh.jar
   ...[all third-paty *.jar]
+tutorial/
      +--costa.3ds
      +--dodec.off
      +--grid.jpeg
      +--README
      +--terrain.3ds
      +--de/
         +--jreality/
                +--tutorial/
                 .....

and ~/.profile

Code: Select all

CLASSPATH=~/jReality/*.jar

in bash I have inputed:

Code: Select all

> cd ~/jReality/
> javac tutorial/de/jreality/tutorial/*.java

then I get the information:

Code: Select all

package de.jreality.geometry does not exist

I have tried javac -classpath ~/jReality/*.jar *.jar and get

Code: Select all

package de.jreality.geometry does not exist

too.

Thanks for your help.

I see two problems: first, CLASSPATH=~/jReality/*.jar doesn't work. You have to list all jar files and separate them with :
Second, you need to compile from the folder tutorial (javac de/jreality/tutorial/*.java).

Hope that helps...

Thank you very much for your hints und tipps.
I did all, what you say, and I can compile. But I can not execute the *.class files

Code: Select all

>java de.jreality.tutorial.Cube01
Exception in thread "main" java.lang.NoClassDefFoundError: de/jreality/tutorial/Cube01/class

What must I do ?

[steffen]

I guess you just have to add the current folder to the classpath. Btw i have just updated the "Getting Started" section, there you can see what is needed.

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

[paulthelazy]

I have done as new Getting Started. It doesn't work.

Code: Select all

>java -cp ../jReality.jar:../lib/jtem-beans.jar:./ de.jreality.tutorial.gereality.tutorial.geom.Cube05
Exception in thread "main" java.lang.NoClassDefFoundError: de/jreality/tutorial/geom/Cube05

I use java 6 and suse 10.x (not exactly, because I can only use Internet at Uni). At home I use ubuntu with java 6 and have the same problem with executing. Oh, I have another question: Can I use ViewerApp at home, of course after I compile all the file in tutorial sucessful.

[steffen]

Did you download the latest version of jReality-tutorial.zip? E.g. Cube05 has moved from de.jreality.tutorial to de.jreality.tutorial.geom.

[paulthelazy]

Thanks for your hints.
I have check the comand and found, that the new jReality-tutorial.zip (I used all new files) hat not the geom folder. Then I have remove .geom in command, it work.
Could you please check the Download section ?
PS: There is a unused "/*" in compile command (fast at end), can you check that, too ?

[steffen]

The download section is up to date, clear browser cache. Or go directly to http://www3.math.tu-berlin.de/jreality/download/

The /*/*.java is for the different sub-packages under tutorial, like geom, intro. etc.

Thanks stefen, the programm works properly.
