[Jscheme-user] load elf/run.scm before elf/classpath.scm

[Geoffrey K. <ge...@kn...>]

I found this old message, which helped me extend my CLASSPATH.
But (load "using/run.scm") is now needed before (load=20
"elf/classpath.scm").

Otherwise you get:
    ($ "java.class.path" )
    SchemeException:[[ERROR: undefined variable "$"""]]

In the latest version of Jscheme the class path used by silk.Import can=20=

be
extended.  See the code in elf/classpath.scm.

So, for example, you can start from the jar and grow the classpath as=20
your
application requires.  Here's an example:

D:\temp\silk\silkweb>java -jar jscheme.jar


Jscheme 4.3.3 (02/11/2002)


  > (load "elf/classpath.scm")
#t
  > (extendClassPath "d:/java/junit3.7/junit.jar")
#null
  > (junit.swingui.TestRunner.main (array String.class))
#null
  >
This brings up the JUnit GUI.

Also, if you need to recompile a class loaded through the extended class
path you can run (replaceClassLoaders) to get a new set of class=20
loaders so
recompiled classes can be loaded through them.  (Any old objects will
behave the old way of course).

Let me know if you have any problems.

One current limitation is you can't recompile and reload any core=20
Jscheme
classes.  A small price to pay for this magic.
