Thanks Danny, that is helpful. I have no GUI yet, I'm just starting with my
servlet stuff and I have servlets like Hello World running just fine on my
PC using the built in web server with JDSK and I got the O'Reilly servlets
book...
I guess what I need to know how to do is take the javacsript or output
strings from the RHS of my rules in jess, and have the servlet interpret
them. There must be a simple way to do it! Main produces output to standard
output, so how do I "capture" the output, or better still, change the output
stream from standard to "internal" (if you know what I mean!!!)?? I'll work
out the http get and post stuff, I have the text for that. I just have very
littl eexperience with output stream stuff.
Thanks so much for your help. ANy comments welcome!!!
