[kepler-dev] jar file locations

[Dan Higgins]

Christopher,

    Thanks for the response. The name problem is that the actual jar 
file name is repeated in different subdirectories; e.g. 
"$KEPLER/soap/soap.jar" and "$KEPLER/apache/soap.jar". We are thus 
ending up with duplicates (or different versions with the same name) in 
the class path. Part of the problem is that we now are ending up 
absurdly long classpaths! This seems to be OK on WindowsXP but causes a 
problem on Win2K. Various Kepler deveopers have added the many jar files 
to support their specific actors so we don;t even include the source (or 
recompile) for these jars.
