[ Please continue sending to lynx-dev. ]

What does the return value from p.exitValue() mean, is it a normal
return value or perhaps a signal number?  You are the java guy, so
you should know...

Try adding -trace to the lynx flags, that should create a Lynx.trace
file in the home directory.  (But does the cgi user have one?)
Or add -trace -tlog, that should dump trace output to stderr.

Lynx needs access to a lynx.cfg file, add -cfg=... to make sure it
finds the right one.  Try setting STARTFILE in lynx.cfg to a local
file://localhost/... URL, and test your app with a file://localhost/...,
to eliminate domain name lookup problems.
