Hmm -- though its no explanation for a crash, why did you choose to install using the existing web server and then start the service (which is unrelated to the built-in server version)? Note that "because I didn't know any better" is a perfectly valid response -- I think we need a better explanation of the options available on NT ;) > > 4.

Is the service you tried to start still running? The two are basically mutually exclusive - both cannot have the persistent object database open at the same time. > I am picking up events in the event logs as follows: > > I definitly think it is a configuration issue here are the > events(4 critical > occur): > > a.The Open Procedure for service "ISAPISearch" in DLL > "QPerf.dll" failed. > Performance data for this service will not be available.

It *looks* like the service failed to start up -- do you by any chance have an existing python installed (esp. a 1.5.2 alpha)? In any event, if you did not choose to install Zope as a service, you will not be able to get to it via IIS anyway. The easiest way to figure out what's going on here is for you to: 1. stop the 'ted' service and make sure it is set as 'disabled' or 'manual' start in the NT service manager. 2. run the serve.bat script in your ted installation to start the built-in server. 3. try to access 'http://localhost:8080/manage'. If you fail to access the management screen, send me the exact contents of the reply the browser gives you (by doing 'view source').

RE: [Zope] - Zope, DTML and XML

I agree. There are already a good number of XSL processors that can do their job far better than we could. We can publish objects out to XML and hand it over to the XSL much more easily (and with better results). I think our XML focus should stay on the exchange of data (input/output) rather than the formatting.

The installer shouldn't let you choose a name w/ quotes or spaces (or backslashes or some other things) in the first place, for other reasons in addition to the problem shown above.

Paul, I don't use Win95 (or Win98) so the following advice could be totally bogus, but you should have a file on your system: C:\windows\hosts If it's called hosts.sam, copy or rename it to hosts. The file should have a line in it that looks something like: 127.0.0.1 localhost If you add an entry that matches what BaseHTTPServer.py considers to be host, you should be okay.

- Is this a bug?
by Butch Landingin 14 Dec '98

14 Dec '98

I've just started playing around with Zope and the Plutonia example so I don't know enough to figure this one out: I defined the standard_html_header as follows : ---start of standard_html_header-------- <HTML><HEAD> <TITLE></TITLE> </HEAD> <BODY BGCOLOR="#FFFFFF"> <P></P> ---end of standard_html_header-------- and in each of the the folders News, Products and Research, there an index_html (e.g. title : Plutonia News) with the following text (or something like it) : -----start of index_html---------  <H2> </H2> <P> Welcome to Plutonia News Section!</P> <P> We don't have any news items to report yet though. </P>  -----end of index_html--------- When the page is rendered, the document_title is displayed correctly as <H2> Plutonia News </H2>. However the standard_html_header template expansion has this quirky behavior : the PlutoniaLogo is translated correctly into PlutoniaLogo but the document_title in between the <TITLE> tags is empty! See the rendered HTML: ---start of rendered HTML -------- <HTML><HEAD> <TITLE></TITLE> </HEAD> <BODY BGCOLOR="#FFFFFF"> <P><IMG SRC="PlutoniaLogo" ALT="PlutoniaLogo"></P> <H2> Plutonia News</H2> <P> Welcome to Plutonia News Section!</P> <P> We don't have any news items to report yet though.</P> </BODY></HTML> ---end of rendered HTML -------- Question: What's the difference in evaluating the document_title inside standard_html_header and evaluating it inside index_html ? Is there no dynamic or recursive expansion of variables at all? Is there anything that I'm missing here? If there is no recursive expansion of variables, is there anyway I can put a dynamically evaluated variable in the standard_html_header so that it displays the correct title? Other than this, I think Zope is pretty cool. _________________________________________________________ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com

- No Zope.cgi
by John Totten 14 Dec '98

When installed on W32 selecting IIS as the server - the install script fails to create Zope.cgi. Checking the code - it should come from inst/product_install.pyc. How do I run this? John Totten

- title property
by Pavlos Christoforou 14 Dec '98

14 Dec '98

Zopoi I just started to play around with Zope and I came across the following problem. I created a document and by mistake I deleted the title property. After that, adding new properties somehow went unregistered and I was not able to add the title property back. Am I missing something obvious? My mind is still a bobo app Pavlos

- Q on product development
by Janko Hauser 14 Dec '98

14 Dec '98

So, one step further, with the new Beta everything went fine. Started to build a new product. Outline: Want to build a Gallery, where owners can add postscript-pictures with some comment. A thumbnail is generated and a page with thumbnail and comment is displayed. The thumbnail is a link to the actual Postscript picture. A Gallery can include other Galleries to collect pictures for different topics. This will be a subclass of a Folder. As this product should be used by many different users, I don't want to fill up the database with all this pictures. So I want to make an object, which acts like a file, but stores only a link to an external file. Subclassing File and overwriting PData -> ready is the BLOB. Q1: Is there already something like this in Zopeland? This could also be used to make dataviewers for big (GB) datafiles. Q2: I can delete the object from the POS, but how do I delete also the external file? Is there some hook I can use? Q3: The development of a package is quite time consuming, because I need to delete the product, restart the server and add the object again. Can this be done faster? How are other people developing packages? Are all writing bug free code :-)? Q4: Would it be easier to build soemthing like this as external methods? I see now, that it is easier, but than I need to implement my own upload scheme and so on. (This are some of the benefits of a product, all the predefined protocolls, right?) Q5: If I want to extent the gallery with some functions, can these be coded as external methods and added to the Gallery object? I have tried it, but a BLOB object, which is only one class of the product does not get the method (defined by def method(self,...): ) Q6: If more and more packages are developed the security screen becomes rather big. How will this be handled in the future? Thanks for any help and insight you can provide __Janko Hauser

- Experimental 'External Objects' Product Available
by Amos Latteier 14 Dec '98

14 Dec '98

Fellow Zopistas: Despite the fact whatever Jim Fulton may think about the merit of the idea, I wrote a first cut at a Zope Product that allows you to plug normal Bobo objects into Zope. It is basically a slightly hacked version of External Method which I am calling External Objects. You can get it at: http://www.zope.org/Download/Contrib It is only lightly tested, and should not be considered official. However, it does seem to let you more or less plug existing Bobo modules into Zope. To use it download the tarball. Ungzip and untar it in your Zope directory. Now shutdown and restart Zope. Now you should have be able to create External Objects. To create an external objects object, proceed like you are creating an external method. Copy your module to either 'Zope/Extensions' or 'Zope/lib/python/Products/SomeProduct/Extensions'. Your module should define some toplevel Bobo objects. Now create the External Objects object. Specify your module name and the names of the objects you want to use. The list of objects should be space delimited. That's it. Now you can access your Bobo objects as attributes of the External Objects product. Notes: If your objects use Acquisition, they will be correctly patched in to the Zope object hierarchy. If your objects use BoboPOS, you should not/cannot store your objects in Zope's object database. I'm not sure what the right thing to do here is... There may be a good solution to this problem, I just haven't though the issue through at all. This is just an experiment, and I only wrote it because I suggested it and no one else seems to have written it yet ;-) Have fun. -Amos
