ChatRoom

Not Zope specific, but may be important for many web-masters... Some days ago I was told to make a chatroom in our site. I took a look at some products, but no one has satisfied me yet. If anybody knows about _good_ chatroom, please let me know ! Where _good_ means: + highly customizable view of the chatroom + non-flickering refresh (I used jzChat from www.javazoom.net, but it uses JavaScript on client side, so refresh is flickering) So, it should be Java applet on client side. It can be almost anything on server side - Java servlet, Java stand-alone application, native binary program, standard IRC server, CGI script, Zope Product, etc... I don't need many channels at one time. If you have seen (almost) ready-to-use chatroom solution, your help is greatly appreciated ! :) ololo(a)zeus.polsl.gliwice.pl /--------------------------------------\ | `long long long' is too long for GCC | \--------------------------------------/

Whatever product / python code defines the MEM class is probably installed in your old instance but not in your new instance... Hope this helps!

Re: [Zope] Newbie SQL problem: Query Error: Cannot render query template
by Stephen Nosal 31 Aug '00

Troy- Have you tried running this from the DOS prompt? I ran into all sorts of problems running 2.1.6 on NT4WS with the ODBCDA. Everything was fine when I used the start and stop scripts from the command line. When I moved to starting zope as a service, my ODBC connections kept failing. Never did find an NT solution, I just moved everything to Linux. It's worth a try. - Steve On Wed, 30 August 2000, "Farrell, Troy" wrote: > > Hello. > > I am running Zope as a service on NT4WS.

Re: [Zope] ALERT: rally to the flag, troops!

I hate it when this happens - I just had the IS department throw out 2 months of work because it doesn't conform to corporate standards. That's because they have no standard and all the developers do is fight over what vendors to use and who will do the development. I hope your project goes better than mine... Good Luck. - Steve On Thu, 31 August 2000, Jean Jordaan wrote: > > Hello Zopers > > This is serious business.

Re: [Zope] How to use DocumentTemplate custom formats from Python?

I did as below, which worked. Is that the official way? - I couldn't see any dedicated function to register a format.

"Z2 CONFLICT Competing writes" and synchronization woes
by Sean McGrath 31 Aug '00

31 Aug '00

(Google -- which normally does an absolutely stunning job of directing me to answers to Zope questions -- has drawn a blank on this one:) I have an external method that writes stuff to a file. I want to synchronize access to the file so that multiple callers can be adding stuff to the file without problems. Without any synchronization I get interleaved output most of the time and occasionally an error message like this: "Z2 CONFLICT Competing writes at, /foo" I tried using the threading module and creating a Lock object as a global in the external method. This does not help as each request gets allocated its own Lock object. I tried Rlock got an error message I didn't understand and concluded I don't know what I'm doing:-) Any pointers to the best way to do synchronization of access to the filesystem from external methods? regards, Sean McGrath
