[Attempto] Installation of local version of ACE view

[Eddy Vanderlinden]

Hello Kaarel,

I tried with ports 5123 and 5623 and get the error message:
    OWL verbalizer error:
    Error accessing OWL->ACE webservice HTTP request failes: HTTP/1.1500 
Internal server error.


Is OK:
    It is started like this:

    owl_to_ace.exe -httpserver -port 5123 = OK

    On success it prints out:

    "Starting owl_to_ace at port 5123 ..."    = OK


The browser shows the expected error on the port's address:
 <error type="existence_error(form_data, xml)">_G2139</error>   = OK

Kind regards

Eddy Vanderlinden

This is an ACE View error message. It means that the OWL->ACE service
is not running, or runs on a different port, or something else went wrong...

OK, I guess you have all the required libraries.

Hopefully, these are not needed.
Note though that you would need libjpl.dll to be able to use
the Attempto Java Packages (i.e. connect from ACE View to ape.exe).
But you don't currently need it for the OWL Verbalizer.

This is correct if the OWL->ACE server runs on port 5123.

This would work if you have added certain URL rewriting
to your webserver configuration file, which you probably have not done,
so forget about it.

So the question is: did you manage to start the OWL->ACE service?

It is started like this:

$ owl_to_ace.exe -httpserver -port 5123

On success it prints out:

"Starting owl_to_ace at port 5123 ..."

and stays running. You can test it by taking your browser to:

http://localhost:5123/

The browser (use Firefox if possible) should display:

<error type="existence_error(form_data, xml)">_G2704</error>

Now, if all this works, then select "http://localhost:5123/" for the
OWL->ACE service
in the ACE View preferences.
If it didn't work, then try another port number, and change the ACE
View settings
accordingly.

Note that you need to restart this service whenever you reboot your 
computer.
So, it makes sense to add the "owl_to_ace.exe -httpserver -port 5123" line
to some Windows startup script. (Once upon a time, there was AUTOEXEC.BAT
for that, but probably not anymore. ;))

Hope this helps,
kaarel
