I'm lost in the swamp... I decided it was time to update my beta
stuff and try some of the big deal stuff on my own machines. So, I
started on the Linux 64 bit installation and got stuck in the mud -
then went to my 32 bit server and got to the same dead end...
In both cases, the first time I tried running jhs I got the following output:
~~~
./jhs
J HTTP Server - init OK
Edit startup to change 65001 or access/noaccess from other machines.
Default startup is: /usr/local/lib/j701/bin/jhs
Requires a modern browser (later than 2004) with Javascript.
A : separates ip address from port. Numeric form ip can be faster than name.
Access from another machine:
http://10.1.2.10:65001/jijx
Start a web browser on this machine and enter URL:
http://127.0.0.1:65001/jijx
~~~
(this after editing jhs to replace the 0 (local machine) with 1
(other machines) - required because the servers don't have browsers
etc. In both cases I was able to get to the jal screen and install
updates. I was trying to get to run the examples below and when I
looked at JAL "Installed" it said I was IDE JHS version 1.0.14
But then - when I tried to kill and restart the server task, it
refuses to connect to an outside machine and the bit in the above
about "Access from another machine:" is missing .... and no more am I
able to have a browser connect to the server.
The only way I have found to remedy this is to delete all of the J701
library, reinstall, edit again the jhs file (for other machine
access) - but then I'm down level without the ability to try the big
deal things ....
or indeed even i. 5 :(
The only consoling news is that jconsole works fine through all of this.
Help?
- joey
PS - I also forgot/lost my last password at jsoftware JUM so I can't
even look at things there :( ^2
(Question - is there a way to start over on that point? Next time
I'll tape my password to the wall....)
