1: Installation Problems: "Document Contained No Data"
Posted by Andrew Boddy on 08/18/00 12:39 PM
I am getting an error that prevents me from using OpenACS.

Netscape returns: Document Contained no data. Another browser (kfm): Confirms this, it asks "Open with...?", when I answer emacs the file is indeed empty.

I have created a little /web/server1/www/index.html file so there is no tcl involved here.

I am running on localhost, not connected to the internet.

I haven't edited server1.tcl so there is still a reference to "somenerd@localhost.localdomain".

Postgres looks happy, no problem loading the tables.

I've pinged localhost OK.

I've included these files:

/etc/hosts
/web/server1/parameters/nsd.tcl
/web/server1/parametere/log/server.log (extracts)
/web/.../access.log (empty!)

Any help is greatly appreciated, I hope this is a simple problem... but not too simple :o) .

thanks in advance ...

Andy

Hi Andrew! did you change the name of your /web/server1/parameters/nsd.tcl to /web/server1/parameters/server1.tcl?, remember to change nsd --> server1 in your case, I guess you are using nsd.tcl that is in site as example http://new.openacs.org/doc/openacs/nsd.txt to run your aolserver, for it is working ok, hope this help you ;)

Hi Rocael,
no, as I understand (and tell me if I am wrong), I have the following: 
/web/server1/parameters/nsd.tcl 
/web/server1/parameters/server1.tcl
nsd.tcl gets loaded (specified in the parameters) by AOLserver on startup and at the end of this file server1.tcl is 'sourced'. So I have two files, one called nsd.tcl and one called server1.tcl .

Yes, I am using the example nsd.tcl ...

Try changing the line: 
set host                   [ns_info hostname]
to: 
set host                   localhost
Also, how are you starting AOLserver?

Roberto, thanks

changing the line to: 

  set host localhost
worked. Can you, for the bonus point, explain why the original line presumably works for some systems and not mine?

Yes, please do explain why. I have had the same problem which has baffled me completely given that I have managed to get the ACS running on a previous setup. Is there a bug with ns_info hostname?

Thanks
