Title: GUI Server 0-1 on Windows2000
Post by: didi on June 07, 2007, 11:40:46 AM
After the first try of  ' newlisp button-demo.lsp ' only the newlisp-console-window was opened.



Then i realised that the Java RE V1.42 wasn't installed by default in Windows2000 .



No problem,  i downloaded the actual version from :

http://java.sun.com/j2se/1.4.2/download.html



The ' java -version' shows now  "Version..1.4.2_14..-b05 "



After that i've got exactly the same error-message that newdep mentioned in the Windows-XP thread.

Any suggestions what to try next ?  ; not  changing the system ;-)

Just install the latest Java 6 RE from Sun. It happened to announce itself on the XP-Home machine I was on this morning, I let it install itself and its running fine.

the (Unsupported major.minor version 49.0)  also indicates a conflic..

It's running !!!



The  'java -version'  command  shows now "Version 1.6.0_01 .. build -b06" .



Thankyou Lutz for the fast help . All demos are working fine !





PS:

The 'console'  and the 'widgets-demo' are partly out of my 800x600 screen, but i think i can change that myself .

I know, I'm still very attached to my old machine .. ;-)
