Docs relating to apps server [Q]
by zope＠infosys.com.ar 12 Aug '99

12 Aug '99

Hi! I will have to give an internal presentation about application servers. I am a software developer and I have to explain what is actually an application server to a web-development group (mainly graphic desginers, html markets and GUI designers). I have to make clear why an app server is best than continue to develop traditional CGI-ish web sites. I can think a lot of reasons (code reusability, delegation, etc) but I would like to have some docs to backup my statements. Can anyone point me to some docs? Some publications? Thanks a lot Cheers, ZBruno :-)

Cannot use rename and other buttons on root folder
by Jim Cain 12 Aug '99

12 Aug '99

When I check one of the items in the root folder and click any of the rename, copy etc buttons at the bottom, it shows me a view of the root folder in the frame. In any other folders other than the root folder, the buttons work fine. What's going on? Thanks, Jim

Abstract for zope seminar at Internal web conference
by Jay, Dylan 12 Aug '99

12 Aug '99

Lucent being the megolith company that it is, has its own internal conference for web stuff. I'm submitting an anbstract for a seminar that I hope is accepted. It is on the work I have done using zope over the last few months. I thought I might send it for you all to get your feedback. Any help you may have would be appreciated. I have to submitt the abstract in about 12 hours or so. "Using the Open Source Z Object Publishing Environment to build a maintainable, data driven customer web site" These days when building a web site there are many tools at your disposal. Recent years have seen the growth of a vast array of solutions for providing services such as database integration, dynamic content, collaborative editing and user tracking. Solutions range from traditional CGI, server-side scripting to large-scale Web Application Servers such as Netscape Application Server. Our group produces a software product called "ProVision". We needed an Intranet web site through which we could sell, distribute, and support this product to the Lucent provisioning community (http://provision.auslabs.lucent.com) We choose the Z Object Publishing Environment (also know as ZOPE, see http://www.zope.org) with which to build the ProVision web site. We found the main advantages of ZOPE are: * Its own OODBMS gives the entire web site transactions, versioning and an integrated security model. * A unique method for reference resolution called "Acquisition" means that scripts and documents can be separated in a flexible and maintainable fashion. * SQL database integration provides connection management, seamless transaction integration and an easy scripting syntax. * That it is built on top of the OO language Python making code both powerful and cross-platform. * An extensible architecture called "Products" that makes it easy to install new functionality and package code for reuse. Products exist for IMAP, LDAP, Web Discussion board, E-Commerse, news and calender rendering amoung others. * The entire site is maintained and edited entirely over the web. * The fact that ZOPE is open source meant that not only did it lower the costs associated with our site, but also it ensured a high level of support from a large worldwide development community. With these tools at our disposal it was possible to create a sophisticated but maintainable web site in about 300 developer hours. The web site now has over 1000 registered users spread over 20 countries. In this seminar we will talk about features of the ProVision site such as a site map that is automatically updated, a registration system with email confirmation and post intergration, and pages with dynamic content based on a user's profile. We will discuss how they were implemented using ZOPE and how ZOPE can bring to your web sites.

Server Lockups: Clue?
by Thaxter, Jason M. 12 Aug '99

12 Aug '99

I was wondering about the lockups at first, since I didn't experience it. When I did, I noticed something interesting. The lockups only affected the management interface. When I accessed zope as an anonymous user (via another browser, of course), not only was the response instant, but the management interface "unfroze" as well. Could this be a threading issue? This is Z-2.0b2 cooked on Solaris 2.6, Python 1.5.2, w/ egcs-1.1.2-release. Hope this helps.

Zope in single-threaded mode using pcgi_publisher?
by Alexander Staubo 12 Aug '99

12 Aug '99

I know you can run ZServer in single-threaded mode -- but is it possible using PCGI and pcgi_publisher.py? -- Alexander Staubo http://www.mop.no/~alex/ "His latest [comic-book hero] was the very exemplar of political correctitude, being a small black boy, who, in the company of his lovable pet pooch, righted social wrongs and put bad boys to flight. Exactly why 'The Adventures of Johnny Foreigner and Dildo the Dog' had so far failed to impress prospective publishers was quite beyond him." --Robert Rankin, _Apocalypso_

Static zope?
by Francisco Sam Castillo 12 Aug '99

12 Aug '99

Hello everyone, I would like to know if someone has a static linked version of zope, or if it would be possible that some one would give me some light on how to do it my self, my case is difficult I want to install zope on my ISP server on my account but they have zero support for threads and it is running slackware wich is incompatible without and upgrade with zope, (the upgrade will not happend any time soon!) so I was told I cud run a static linked version of zope instead of the dynamic version of it available at this time, if some one has done this would you contact me please? or if some one would give me the steps necesary to compile zope statically I would appreciate it a lot, as I been working a lot on a new zope driven site and now I can't publish it and it is just frustrating, (I think there should be a static distribution of zope included on the Zope download area as I am not the only one having problems compiling or running zope, maybe a good idea?) thanks a lot in advanced!

[Fwd: [Zope] A few quickie (newbieish) questions]
by Joe Grace 12 Aug '99

12 Aug '99

Dear Zope'sters, I would dearly appreciate a little help if possible. Thanks, = Joe = P.s., I'm using Zope 2b3 (not b1). -------- Original Message -------- Subject: [Zope] A few quickie (newbieish) questions Date: Wed, 11 Aug 1999 07:58:53 -0700 From: Joe Grace <occam(a)serv.net> To: zope(a)zope.org CC: me <occam(a)wizards.com> Hi, I'm hoping I can get some quickie questions answered which have been nettling me (I'm using Zope 2b1). I'm getting some good stuff working, but it seems to be a few nagging, simple things which are tricky. Rather than just finding a (probably overly complex) way, I'm hoping someone(s :-) can set me back onto the Zope Zen path for idiomatic simplicity. (Other Zope idiomatic tips would be welcome as well.) Hmm, perhaps a Zope idiom document would be nice!-) 1. Custom dates with correct timezone?. I store a date using fmt="aCommon" in a folder property. Works great when I display it using fmt="aCommon" meaning that the time agrees with the time in my current time zone (PST). It also lists properly from the FolderName/Properties Zope management page. However, when I try to display it as fmt="%b/%d" or fmt="%x %X", the time (or day) is off by 7 hours ahead. Is there an easy way to get custom dates with automatic timezone accuracy (i.e., what am I missing?)? 2. Avoid duplicate pathing? How do I refer to the current folder properly (e.g., for a reload)? Perhaps I just need to reload? I tried FolderName by acquisition which "worked" except that it keeps appending a new FolderName to my address each time its used, e.g., ".../FolderName/" becomes ".../FolderName/FolderName/". What is the Zopish way to get the same behavior but without the duplicated FolderNames? 3. Correct (simplest, most robust?) server-side interconnect for Zope and Java (e.g., JPython)? Hmm, maybe this isn't a quickie, but help/pointers/options would be welcome nevertheless. Is there a standard way to get my java talking with Zope? Perhaps *CGI is the correct tool for this task (I'm new to web stuff)? Basically, I want to get my Zope and Java talking closely. Performance is not a key issue (but nice of course for scalability later on). Right now, I'd just like to get stuff working in some proper (hopefully standard) way with the option to optimize later on. One suggestion I've heard is XML-RPC which certainly is interesting but seems a little heavyweight perhaps since I'm willing to have python talk directly with JPython. (Wishful thinking alert!-) Is there some tricky way to get Java and Zope running in-process together? Short of that, are there some standard options for this sort of thing? Thanks in advance! BTW, I'm enjoying my Zoping. I added several features to my site on request yesterday which was nice turnaround for a newbie. Zope can be very satisfying to use! (Thanks DC!)
