You need to run the original Java version from Sun. The preinstalled GNU versions on UBUNTU are still not compatible.



Download the Java SE Runtime Environment (the full development environment is not required).



Install it anywhere, e.g. in usr/local/ and make a softlink link of the java executable to /usr/bin/java. On my machine this went like this:

Code Select Expand

ln -s /usr/local/jre1.6.0_13/bin/java  /usr/bin/java

I downloaded this: jre-6u16-linux-i586.bin, not the RPM version. You run this as a script in /usr/local as administrator or using sudo.



ps: on this page http://java.sun.com/javase/downloads/index.jsp">http://java.sun.com/javase/downloads/index.jsp scroll down to the title "Java SE Runtime Environment (JRE)"

I just end up with a bunch of "retrying to connect" messages and, finally, "server could not connect to 0.0.0.0:47012".



I'm running fedora 10, and my firewall isn't blocking local connections or anything - it doesn't work with the firewall off, either, and selinux is running permissive.

[Lutz]

What version of Java are your running? Should be the original Sun JRE. Do you have the soft link to /usr/bin/java ?

1.6.0.16

Yep.

Normally when doing:

Code Select Expand

$ newlisp-edit

;or

$ newlisp my-gui-app.lsp


$ is the shell prompt. newLISP starts first, then the newLISP process starts the Java server.



47011 is the port for newlisp <--- guiserver

47012 is the port for newlisp  ---> guiserver



Instead try this:

Code Select Expand

java -jar /usr/share/newlisp/guiserver.jar 47011 /usr/bin/newlisp-edit

or any other of the demo apps instead newlisp-edit. This starts the guiserver first.

[Jeff]

Same again:

newLISP-GS v.1.32 on Linux

 double buffering supported.

guiserver starting newLISP "newlisp /usr/bin/newlisp-edit 47011 javastart &"

guiserver finished exec

 listening on 47011

 accepted connection from 0.0.0.0

 connecting to 0.0.0.0:47012

 retrying to connect

 retrying to connect

Thanx, it works. I have replaced link /usr/bin/java on version 1.6 and GUI works now.

[Lutz]

I am glad it works, but I wonder about the screen shot you posted earlier, because half of the editor/IDE was missing there.



This is how the editor (left in the screen shot) should look like:

Yep, it has now a «test» part downwards, where I can try to evaluate something. I have marked on your screenshot windows I have. Can not post a photo of my own screen right now, because I'm at the home already, using another PC.

The other windows are just demo applications accessible from the Help menu.
