I didn't want to be rude.  :-X

How can I change the classpath variable to absolute paths?

A pde.jar ist in the arduino directory. But there is no subdirectory.

Thanks for new suggestions.

PS. I'm here in a Arduino Workshop. All Mac are working thin. All 5 PCs don't work.
Some have the same problem than I have ...
Why does tha Arduino-Editor don't work standalone without Java?

Thanks for the help.  

I tried to edit set JAVA_HOME=""

set JAVA_HOME="C:\Program Files\Java\jre1.5.0_11\bin\"

But I get an error:

Exception in thread "main" java.lang.NoClassDefFoundError: processing/app/Base  

What do I wrong?

I'm working with WinXP. Unzipped Arduino_Inst. Installed latest Java Version.

But everytime I try to open Arduino.exe I get this message:

Error: could not finde java 2 runtime environment

Does anybody know help?

We would like to invite Massimo for a one day workshop
at the Tweakfest-Festival in Zürich from 24. - 26. Mai 2007.

Sounds good.

Would be great if you could give me your email contact. Thx.

Is there anyhow an other possibility to contact the
arduino crew than the forum? E-Mail?
