I'm having a little difficulty getting my head around this stuff. Is there source code for a demo site that implements frames, navigation bars etc. I tried looking to find the source for the online help but couldn't see how to get at it. Thanks, ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz

To Zope or Not To Zope?
by Ryan Daum 26 May '99

26 May '99

A client of ours has approached us about designing and building a major web portal project focused around a particular topic area with extensive member services and content management abilities. We now have to spec this project out and at some point in the near future I will have to decide on a WWW server/Application server/Database combination. Zope is in the running, along with WebObjects, NetObjects, ODI's ObjectStore + ObjectForms, etc. My initial impulse is to go with Zope because of its low cost overhead and my expertise with Python as well as the access I have to this mailing list and so on. Unfortunately my desire to do implement python is offset by a few major concerns, and I would like to see if anybody out there could address these questions/concerns: 1) Zope seems to want to operate in a configuration of web server, application server, and object database all in one package. I have managed to get Zope to run using ZServer + Apache PCGI, but the performance seems quite quite dismal. My concern is mainly scalability: I want to be able to use an industry standard web server (i.e. apache) separate from the application server so that I could do things like scale using multiple web servers, etc. etc. 2) The same issue applies to the DB layer. After floating through all the documentation on the zope.org site I am unclear what the relationship would be between Zope and an industrial strength database like Oracle 8, etc. I am wary of using Zope's own object DB because of scale and compatibility issues, but most of the benefits of using Zope would be mitigated if I ended up having to write SQL queries to access my Oracle database. The question is: is it possible to use a DB like Oracle or Postgres, etc. transparently and in the same manner that I would be using Zope's native db? How about an object DB like ODI's ObjectStore? 3) Zope is not "standard" enough that should I get run over by a truck development could proceed without me. Finding consultants and programmers other than myself to work on this project could be difficult. 4) At this moment in time my tendency is to want to sell the client on implementing Apple's WebObjects + Oracle8, but the cost overhead of that choice would limit the amount of revenue available for working on the project. What are other developers experiences with WebObjects, and how would they compare them to Zope? Any help would be greatly appreciated. Ryan

Bug ?
by Tom Deprez 26 May '99

26 May '99

Hi there, I think I found a bug in 1.11pre and I just let you know about it, because it can possibly be also in Zope2.0 The bug can be found in the tree tag. At ZDP, we've made a tree by which every branch refers to an url document. Now, I installed Zope1.11pre (for testing) at my home on a Windows95, with ZServer. I've exported a part of the tree of ZDP and imported into Zope on my old PC with Windows95. If I click on an url on my PC, I get an error message : Zope Error : Zope has encountered an error while publishing this resource. AttributeError : Sorry, a Zope error occurred. This doesn't happen on ZDP. I think this is a bug. But I don't know if it is because of Zope1.11pre, or windows OS. Tom.

Printable Page (Newbie Question)
by Albert Kinderman 26 May '99

26 May '99

I like the look of the Zope site, although it could be better organized. 8=) I have started my site with a navigational tree on the left side. I want to offer printable pages, with the tree gone, just as the Zope site does. Is there a how-to reference?

Problem with Zope & Apache
by Corey Ralph 26 May '99

26 May '99

I am having a problem with zope & apache. Everything works OK except when I try to make any changes in the manage, I get a window saying "the document contains no data", and it according to the logs, the apache child process caused a segmentation fault. With the built in zope http server I have no problems at all. Any ideas?

> A Windows binary would be very useful. It's no problem to compile > something with gcc, but I don't have a windows c compiler. Binaries will have to wait until the beta release cycle. Our policy is that we will not make binary release of alpha quality code. While 1.11pre was intended to be released, early feedback indicated that it had a much longer way to go. Stay tuned, we are working out a more formal release model, so people can understand where and when releases will happen. Chris

new ZDP docs
by Martijn Faassen 26 May '99

Hi there, The Zope Documentation Project's been busy! Visit http://zdp.zope.org and find new documents. Note that all of our docs are in draft state and in constant flux, but we think they can still be useful. If you have suggestions, the ZDP is all ears. Regards, Martijn

RE: [Zope] OT: Help a newbie install Zope 2.0!
by Chris Petrilli 26 May '99

26 May '99

> [Question about newbie installing 2.0alpha] For the same reason that we will *not* provide binaries of the alpha releases (and may only provide them for later betas and "release candidates"), alpha are certainly not a good place to start for someone new to Zope, especially if you do not have extensive experience with Python and whatever platform you are running on. This only begs to have all kinds of problems related to issues outside our control. I would recommend you start with 1.10.2, as there is plenty in there to get your head wrapped around before delving into the new features of 2.0 ... even once 2.0 is RELEASED, it is still a x.0 release, and therefore is really only for those people who NEED to be on the bleeding edge (i.e. because they'll need ZClasses, or some such), rather than a general populace release.
