Re: [Jython-users] CLASSPATH problem under Tomcat

[Sarwar R. <raz...@ya...>]

I was able to fix my problem using Jaroslav's registry
file fix. Thanks!

I am trying desparately to NOT have to specify jarfile
locations in my classpath (i.e. in my autoexec.bat or
.login file). I'd rather supply them as command line
args. 

say, I heard a while back that O Rieley was doing a
vol. on JPython? Whatever became of that? any
references for a good tutorial online? 

Thanks
