[Jprogramming] CGI puzzle

[Joey K Tuttle]

Thank you Bill and Raul.

I finally remembered that in past versions of j I had to put a SetEnv 
statement in the Apache configuration file. In the past it was for 
JPATHjxxx, which was replaced (and new flexibility much appreciated) 
in j602. But, it seems that apache doesn't have a HOME environment 
variable set. That causes the line (in j602/bin/profile.ijs):

home=.    >(systype-5){(2!:5'HOME');(2!:5'USERPROFILE');'\My Documents'

to return numeric 0 for home, then in the subsequent lines:

userx=.   '\j',('64-'#~16={:$3!:3[2),'602-user'
user=.    home,userx

my domain error occurs in the second one... My solution was to add 
the following lines to /etc/httpd/conf/httpd.conf:

# a HOME for Apache to use j
SetEnv HOME /tmp

I suppose some changes in profile.ijs might avoid the need for 
changing Apache's configuration file. In any case, I'm happy having 
solved this.
