I remember reading artcles from Tim O'Reilly saying that Zope was the great open source hope for building "web services". Out there in buzzword land, web services means ebXML, BizTalk, and .Net. But I do not see any mailing list discussions or articles explaining how Zope would fit into these frameworks. Is this because: 1. Zope folk are astute enough to realise that all these frameworks will not come to anything anyway. 2. Most of the people involved with Zope are building intranets / content managemnet systems / general web sites with it. If someone comes to them with a big contract to develop within .Net or ebXML, they will start thinking about it. 3. Zope does not have much to offer. These systems are going to built with vast libraries of Java / C# code in big enterprises which have traditionally not shown much interest in Zope. In short, Zope does not really fit in. I cannot believe that the reason there is no discussion is that the Zope architecture is not suited to these frameworks. If the XML / SOAP side of things were more polished, it would form the perfect platform for developing such services.

Re: [Zope-dev] Traversal Barf
OK, I've found out some more stuff about the problem. Of course, it wasn't really random. The culprit is a linked stylesheet. Every time I alter the sheet in some way, I get the SERVER_URL KeyError. I can't really see why this should be happening, though. The absolute_url() in question is in the main body of the document, not the stylesheet. Is perhaps the acquisition wrapper not getting applied to the document until after the linked objects are also downloaded, or something strange like that? I haven't the time time to pursue this right now, but I'll attempt to make a simple, reproduceable example and submit it to the Tracker. But just in case I get time to debug it, where might I start?

[Zope-dev] masquerading python products as functions
Hi, I am trying to make a product act like an external method, or dtmlmethod. Basically I have taken the minimal product and added a __call__ function. It works fine, and can be called as a function of the object that contains it. The problem is that the minimal objects namespace is also pushed onto the stack, and to get out of it I need to go through self.aq_parent. Reading though all the help I could find I tried adding the following (as DTMLMethod suggests.) #Documents masquerade as functions class func_code: pass func_code=func_code() func_code.co_varnames='self','RQUEST','RESPONSE' func_code.co_argcount=3 This doesn't seem to do anything to the namespace problem. Actually, reading through DTMLMethod and ExternalMEthod aren't helping at all. mapply.py seems equally unhelpful, though I can see some of what it is trying to do. Reading it also made me wonder why people say the above code make Documents masquerade as functions, it seems in mapply, that if __call__ is defined, then it is bound to f in mapply anyway. It seems to me to be in the __call__ method that things are important where namespaces are passed to HTML.__call__ I am obviously missing some fundamental points or sequences that would help me to understand this, I was hoping someone could point me in the right direction, either documentation, or some simple explanation, that would make reading through that code more obvious.

Actually, I'm not sure you need to do anything special at all. If you use
the File DataSkin in a Folder w/Customizer Support, you shouldn't need to
do anything special, because in that mode the 'id' attribute is never used
by ZPatterns. If you need to use these File DataSkins in a Rack, though,
you'll need to include a SkinScript that says::
WITH SELF COMPUTE id=getId()
Racks still use the "id" attribute directly, I'm afraid. Your '__init__'
method will still need to accept an 'id' parameter, also, and you'd need to
set the __name__ attribute instead of id. Ugh.
Anyway, I will take a look at Rack and see if it can be made to use the
'getId()' and 'setId()' methods. Of course, you can also subclass Rack and
replace the '_getClientID(client)' method with one that uses 'getId()', but
it might be that I could do this safely in the base Rack class.
The SkinScript examples should also probably be changed to use 'getId()'
instead of 'id' so that people don't use them as a justification for
continuing to indulge in deprecated behavior. :)

Re: [Zope-dev] Management Interface in ZODB
Okay everything works as it should now This patch allows you to store the Zope management interfaces inside the ZODB. It does this by making the manage stuff inheritable and giving the defaults to the root of the folder (This means that the management can't be changed for the root folder - which in my opinion is a good thing.) To override the manage_page_header, all you need to do is create a DTML Method (other method types should work as well but haven't been tested) with the id manage_page_header. This will replace manage_page_header for ALL object below the folder the method was created in. This means that you can lock your self out of the management screens (say by putting
[Zope-dev] How long below the radar?
Hold that thought. In order to fully answer the question I have to ask myself why I choose to use a "below the radar" system in the first place. I'ts said that nothings truly *Free* as in product advertising everything has its cost. When we look at the *cost* compared to other systems Zope/Python wins hands down in all the *right* areas. Its just plain abuse of money and power that keeps Zope/Python where it is. Does'nt matter if it's coming from this camp or another something must be done soon. It boils down to this. Back in the old days if you had something faster, quicker, and better you cleary would be the winner. Too many people were worried about their evestments so of course they stuck with the *hot* tickets. But it would be too expensise to go head to head with the big boys no I think that true interprise is going to be in turmoil. For Instance now that things like MCSE, and CISCO are now part of public college institutions that means what? The climate is such that if its not Microsoft or Sun forget it. I'm not knocking either company I support them 100%. But here's my example. I'm taking a course at a local college and I sit next to a guy that says he only needs to get his MCSE and he will be gainfully employed. I asked him if he felt the need to learn any programming languages and he said no. I doubt very much that this person would ever be inclined to select anything Zope/Python. The big companies spent their money well. Do like they do.DC needs to create Zope Certificatied Desginer/Technicans and shops. Make it commercial *looking* as *freely* possible. Ok back to whats wrong with it. Secure E-commerce Support out the box is one thing. I think we need to hear more of zope coming from out of the major players mouth as a major player. Or is it? There are quite a few choices out there, but what really makes Zope/Python the clear winner. They already have most of the commercial qualities needed to be the best of the best. We have to make them see the value. like Red Hat Distros, Certifications, and plug and play software. Things like Talk shows would be nice. Hey I got dibs on the Zope Certification/Testing center track/fishbowl/proposal thing if one doesnt already exist? and it's possible for a 3rd party to do such a thing. The thing that I can't understand is that in my state the government workers threatened to strike, and dot-coms failed because of money problems. They also have millions tied up in building a technology center. My thing is that Things like Zope/Python should be taught/used right along side the others in the schools. DC should be sending free to schools an easy to install package that allows them to have some limited *commercial* looking front-end.

This actually points to a lack of an acquireable REQUEST object. If you
look at the code in absolute_url, it tries to acquire REQUEST and if it
can't, it sets it to {}. Then when it does a REQUEST['SERVER_URL'] later
on it gets a KeyError. I personally think this code is very brittle, but
it does work 99.99% of the time.

Is it truely random or an every-other reload sort of regularity? I have

The browser differences may point to caching differences that make it

[Zope-dev] How long below the radar?
Case in point. I'm at my local technical college library looking for material. No books on UML or Python. Ok fine they don't teach either one. They don't plan on carring a copy of the Zope book when it comes out. btw wondering when do the people that won *free* copies get theirs. I should be on that list. I made suggestions on what I could do to petition/campaign them to carry the book, and they said write something up. Personally when I think of *library* I think of a respository of tidbits of information stored in some manner for me to conviently access. Zope is free for anyone to access and use. It is a tool and it is knowledge. Something must be wrong if the library is skewed towards closed source commercial products because students aren't getting the *big* picture. If you asked me and I were in charge of and the leader of OSS I would go after half. If commercial products are going to be in public schools like Cisco, and Microsoft, then so should OSS. This way if you shoot for half you'll end up with something.

[Zope-dev] guid
Hi, does Python or Zope have native facilities (i.e., not depending on CoCreateGuid()) for generating guids? If not, what do folks generally use to generate globally unique identifiers?

[Zope-dev] Help !!!
Hi, I'm a student, doing my Masters in Clinet/Server Computing. I was interested in Content Server stuff, thats why I decided to do my master project on Content Server. I was going through the web, and found Zope Application server, and decided to work on it. Right now Zope works with any web server that supports the Common Gateway Interface (CGI). I want to develope some adapter that will enable Zope working with any web server that supports ASP. I downloaded the Zope source code that is available at http://www.zope.org/Products/Zope/2.3.3 I want to play with the source code of Zope application server to have a better idea of this application, but couldn't find any good documentation. I'm wandering whether thats the only peace of code availble for users? Is that full source code for Zope Application server, if not where can I get the full source code? Do u know any documentation which will be helpful for understanding and playing aound with source code?? Please respond to this mail if u have answer to my questions. Thanks, AtulDo You Yahoo!?

One of the links on that page ends in -src.tgz. That's the source to Zope.
