You might want to make sure your classpath points to the *directory* above
where all the jess\*.java are located (remember - jess is in a package.)
For example, if you have the jess distribution installed here:
c:\jess\jess50
the actual jess *.java & *.class files should be in this directory:
c:\jess\jess50\jess
To confirm this, look for the file:
c:\jess\jess50\jess\Rete.java
and
c:\jess\jess50\jess\Rete.class
For deployment, you don't need the .java files but this example assumes you
compiled them in the same directory as the source files.
Your classpath should point to:
c:\jess\jess50
and *not*:
c:\jess\jess50\jess
because java is looking for the package name "jess" below any of the
directories specified in the classpath.
Enclosed is a minimal jess program and a .bat to make it work.
Note: I would not place the "current" directory (e.g. ".") in the classpath
since you may accidentally pick up the wrong class files, or worse, not find
your class files because the notion of a current directory can change over
time (even once your program is up and running) and is especially
problematic for RMI.
For this reason, the classpath.bat I enclose references all of the
directories explicitly ("c:\testjess" is where the test main.java program
resides.)
Using jess from a .jar/.zip file is basically the same. Just make sure the
classpath points to the .jar/.zip filename (e.g. "set
CLASSPATH=c:\jess\jess50.jar;other paths here" etc. etc.) and that the
.jar/.zip file was created with the subdirectory structure starting with
"jess/" (e.g. your .jar should contain the following file -
"jess/Rete.class")
Good luck!
