GUI Error

[yewklid]

I have just today installed NewLisp 10.4.0 on a PC running Windows 7. When I click on the Newlisp icon I get an error message from the Java Virtual Machine Launcher saying "Could not find the main class: C:Program Files(x86)newlispguiserver.jar. Program will exit."

I'm puzzled because when I look in that directory I see a jar file called 'guiserver'.

Any help would be gratefully received.

These are the preconditions for a successful startup:



- Make sure the installer left an environment variable NEWLISPDIR, which should point to

C:Program Files(x86)newlisp



- You also need a C:temp directory or an environment variable TEMP to point to an alternative directory.



- newlisp.exe must be in the path for executables - set by the installation



Here 4 methods to start the IDE manually:



Go inside the newlisp directory:

Code Select Expand

cd "C:Program Files(86)newlisp"
at the prompt issue one of the following commands:

Code Select Expand

newlisp newlisp-edit.lsp
or:

Code Select Expand

guiserver.jar 47011 newlisp-edit.lsp
or (it's javaw no java):

Code Select Expand

javaw -jar "C:Program Files(86)newlispguiserver.jar" 47011 newlisp-edit.lsp
or:

Code Select Expand

"c:Program Files(86)newlispguiserver.jar" 47011 newlisp-edit.lsp

Depending on your Java installation and environment variables, one of these methods should work. Of course, you also can start newLISP without the IDE by just executing: newlisp



Also inspect the "properties" of the newLISP desktop icon. It should show the correct paths.

Lutz - Many thanks for your help.

 Initially, none of the suggested methods worked but the error message from method 3 said that javaw wasn't recognised. I installed the 64 bit version of java in addition to the 32 bit I had already installed and now method 3 works.

ie using

Code Select Expand

"javaw -jar "C:Program Files (x86)newlispguiserver.jar" 47011 newlisp-edit.lsp"

The other 3 methods still give the same error message.



I managed to get some simple examples like fibonacci and factorial to work. When I tried some of the demos like pinball,I once again got the original error message.



Many thanks for you help so far.

It would be great, if we can get to the bottom of this strange behavior.



Perhaps, if you copy the GS demo files into the current directory, they will work. Just like newlisp-edit.lsp is working, but only from the current directory, not using path names.



Can you post your variable environment - just type 'set' in a command shell - ?



There should also be an entry in the registry to associate the .jar extension with javaw.exe.

Copying the pinball demo to the newlisp directory didn't help.

The environment table is below.

The environment looks perfect. This must have something to do with the Java installation. I wonder if anybody else has seen this problem?

At last - some progress!

I tried double clicking on the file guiserver.jar itself and got exactly the same error message. Then I right clicked and looked at the 'open with' option. Surprisingly I was given a choice of the java platform binary three time over. I tried all three. One of them lets me get a bit further. I get the Newlisp GUI up and running, load the pinballs demo and then try to run it. This time I don't get the 'guiserver not found' error. Instead, Newlisp produces this:
