J GUI must use sun java, not other implementations. For political reason sun
java is not installed in some linux distributions (eg. ubuntu) and you have to
install sun java yourself. try java -version again to verify sun java is
installed, if not, install it first.
after that you will have 2 (or 3?) versions of java implementation installed, so
that you have to configure sun java as the default. I googled and found this link,
http://www.fedorafaq.org/#java
that might be helpful.
PS. I've never use fedora so that my knowledge is limited.

Thanks. The command line version seems to work fine. I used APL on the job
thirty years ago and am enthusiastic about exploring J.
I also tried running the GUI version jw and a window opens up
with the following as the first two lines:
|domain error: wd
| wd BUF
At that point it seems to lock up, and neither the menus nor the
keyboard can be activated.
Typing in java -version tells me I'm using java version "1.5.0" I know how to
add a directory to my PATH but I'm not sure where what I might need to add would be
located.
Thanks again.

the source of your problems.
Use mv to move the j601 folder from HOME/J to HOME (or redo the tar -xzf
install step from your HOME folder).
After this correction your should be able to start both the console version
of J (~/j601/jconsole) and the GUI version (~/j601/jw).
You can have your j601 folder in other than HOME but it requires a few
additional steps.
The upcoming J602 linux install is much improved and won't have any of the
problems that have plagued you thus far.

Subject: Re: [Jgeneral] J installation on Fedora 7
Thank you for responding. Continuity from one post to the next seems to be
getting lost with some responders so I'll only communicate with you from
this point on.
OK, one more time.
I downloaded j601c_linux.tar.gz to a new folder named J
I unpacked it with the Archive Manager which created a folder j601
Here is what happens when I "follow the instructions" for Linux 32 bit
install in install.txt.
[EMAIL PROTECTED] ~]$ script
Script started, file is typescript
[EMAIL PROTECTED] ~]$ cd J
[EMAIL PROTECTED] J]$ ls
j601 j601c_linux.tar.gz
[EMAIL PROTECTED] J]$ cd j601
[EMAIL PROTECTED] j601]$ sudo mv libj601.so /usr/lib/.
Password:
michael is not in the sudoers file. This incident will be reported.
[EMAIL PROTECTED] j601]$ su
Password:
[EMAIL PROTECTED] j601]# mv libj601.so /usr/lib/.
[EMAIL PROTECTED] j601]# exit
exit
[EMAIL PROTECTED] j601]$ exit
exit
Script done, file is typescript
[EMAIL PROTECTED] ~]$
OK? So I became su to move file libj601.so to /usr/lib
I am NOT networked, if that matters in some way.
Next I tried to run jconsole. This is what happens:
[EMAIL PROTECTED] j601]$ ./jconsole
|file name error
| 0!:0 y
Looks like a failure to me.
The instructions then say:
If jconsole fails the likely problem is with the sudo step.
No, I've never used sudo before, don't really need to if I'm su.
What now?

sudo is a standard linux command and not related to J. It is strange that
you
can su but not sudo. Did you use sudo in Fedora before? Do you know the
superuser password for your Fedora?
