Setting up a new windows system for java clients
Q: I am trying to run our (admittedly old...) Illuminator tool on a new Windows 7 system. I have set up Java before to run the illuminator.bat file directly, but I'm getting this generic java error:
$ ./illuminator.bat
Exception in thread "main" java.lang.NoClassDefFoundError: osedbg/launchpad/Main
Caused by: java.lang.ClassNotFoundException: osedbg.launchpad.Main
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

Could not find the main class: osedbg.launchpad.Main. Program will exit.
jemi@USPHOWS130 /cygdrive/e/OSE/OSE4.6.1/win32/bin
$ export PATH="$PATH;E:/OSE/OSE4.6.1/win32/bin"
jemi@USPHOWS130 /cygdrive/e/OSE/OSE4.6.1/win32/bin
$ echo $OSE_ROOT
C:/OSE/OSE5.5.1_PPC
jemi@USPHOWS130 /cygdrive/e/OSE/OSE4.6.1/win32/bin
$ export OSE_ROOT="E:/OSE/OSE4.6.1"
A: First off, make sure you have jre 1.6 reachable, somewhere. It should have been installed in the OSE4.6.x area but you can use your own version as well. Then make sure you have these environment variables defined before you invoke illuminator.bat:
$ export OSE_ROOT="E:/OSE/OSE4.6.1"
$ export PATH="$PATH;E:/OSE/OSE4.6.1/win32/bin"
$ export CLASSPATH=".;E:/OSE/OSE4.6.1/win32/lib"
(the CLASSPATH may or may not be necessary depending on which java you're using)
IF you set up all this, then Illuminator should finally kick off correctly.
Q: I got Illuminator up on Windows 7 finally. But now I am seeing a flexlm license error "no such license", but I know that the license file is indeed being pointed to in the correct place, where $LM_LICENSE_FILE says it is.
A: For reasons unknown, the Java client for Illuminator is looking for the user's license file in a preferences file, illuminator.prf . This is thought (at least, by Illuminator) to reside in some place like "C:/User/jemi/illuminator.prf." If you touch this file, and you'll likely have to since it doesn't actually exist yet, you can edit it to add this line:
LM_DEMO_FILE = C:/flexlm/license.dat
That will greatly aide your Illuminator to find the correct file and remove the error.
