Well, I have now installed Jigsaw on a Sun Solaris host, and everything
works wonderfully. Both Servlets and cgi-bin work as I expected them to.
The error I see above is specific to SGI host, and I was running IRIX 6.2.
Of course I'd like to have it resolved for this host as that is my eventual
target host on which I am to run the server.
So I'd appreciate any feed back you are able to provide.
Oh, FYI the JDK on my Sun Solaris is 1.1.6
