When I set up a KebasData instance following your Zope News example, I get this error message when I try to initialize:
-----
Kebas Data not initialized. Message returned by target server: Moved Temporarily (2003-12-15 09:12)
-----
I've tried both http://www.zope.org and http://zope.org, but each time I get the same result.

Ultimately, if I apply your instructions to a stock installation of Plone 1.0.5 (Win 2K Pro), here is the error message I see when I try to visit the home Plone page.

i put all these stuff in the portal_skins/custom folder

i didn't test this setup at the plone root folder

Putting these files in the custom folder helped. Here are the problems I've encountered with this example so far.

• The name of the KebasData instance is not specified. I named mine "zopenews".
• Zope.org returns a "temporarily moved" error when you try to connect to it through Kebas. I changed the URL to "http://www.plone.org".
• You need to make sure that "q, b" is entered in the Parameter List box on the Script editing page. Putting "q, b" in with the rest of the Python code doesn't work. This may be obvious to Python veterans, but it was something a Python newbie such as myself had to figure out.
• The "zn_slot" code doesn't work. The line
  < x tal:replace="structure here/zn" /> is wrong because you haven't defined any "zn" to date. When I replaced "zn" with "zopenews" and clicked the Test tab, this is what I got back in the section where the Kebas data should be:
  -----
  

  ...
      <div class="body">
          <div class="content">
          <KebasData instance at 01A6A440>
      </div>
  ...
  

• When I create the Plone slot and view the front page, the "Links" slot is empty.

At this point, I can see the links that Kebas has captured when I click the View tab in my "zopenews" KebasData instance. But those links are not being relayed to Plone.

Any ideas?

Thanks!

my bad. i assumed that zn is the kebas instance id. i'll be more explicit next time. same thing with the parameter list.

if you have a temporary moved, it's because apache redirects from http://www.zope.org to http://www.zope.org/

notice the last /

it's the natural behavior by most web servers, iirc. if the last path is a directory, the web server will give a 302 and puts the last /.

so, in the url, make sure the last / is there.

now, the slot. if the kebas id is zn, it should then work ;). in your case, the method is not called, causing zope to blurt out the instance stuff. if i'm right, you might be using a kebasdata version that doesn't have the __call__ method. iirc, version 0.8.1 should have that. if not, i'll put out a 0.8.2 up.

to work around this, use <x tal:replace="structure python:here.zn.view()" /> instead of the one listed above. also, replace zn with your keasdata id.

hth

This line fixed my problem:
<x tal:replace="structure python:here.zn.view()" />

The slash at the end of the www.zope.org URL didn't make any difference. I can't contact Zope either way. I can contact the Plone site, so I'm using that as my example. If you are running Apache in front of your Zope installation, that might be a configuration issue on your end.

I have a request. It would be cool if you could route the links captured by Kebas into another Plone slot. For example, if I clicked a link in my Plone News slot (which was created by Kebas), the output from that link would end up in the center slot. That would allow me to manipulate external content while maintaining my basic Plone navigation. I'm sure it wouldn't be easy to do, but you were asking for requests!
:-)

Thanks!

it surely can be done.. but the legal implication is unknown.

I haven't had any luck with trying to turn your UserFriendly example into a Plone slot.
I created a folder named "demo" inside my Plone folder. Inside "demo," I added a userfriendly Kebas instance, following your instructions. The userfriendly Kebas piece successfully grabs the strip from the external site. I have two items in my "demo" folder: userfriendly (the Kebas instance) and userfriendly_method (the DTML method you suggest). [I tried using your Python script as the userfriendly_method, but Zope rejected the Python script.]
In the Plone > portal_skins > custom folder, I created a "userfriendly_slot" DTML Document. That document contains the following code:

<dtml-var standard_html_header>
<dtml-var "userfriendly.view()">
<dtml-var standard_html_footer>

I'm going through the Google example again, but there are some problems.

• You forgot to include the Google URL that you think Kebas should use. I assume that is "http://www.google.com".
• If you intend to use the Google home page, the pattern (from what I can tell of the current Google home page) should be about <b>(.?)</b>|<p>(.?) - <a href="/search
• When I try to initialize the Kebas instance (with "http://www.google.com" as the url), I get this error:
  

  Kebas Data not initialized. No match found. Check your regex pattern ,URL or proxy setting (2003-12-17 15:53)

  
  
• If I reduce the pattern string to <a href="/search, Kebas will initialize. If I then click the View tab, Zope will display "Not Found".
• If, at this point, I view the "srch" method, Plone will return this error:

  Error Type 
  KeyError
  Error Value 
  srcid
  

  
  
• If I test the "t" Python script, I get this error:

  Error Type 
  NameError
  Error Value 
  global name srcid is not defined
  

  
  
What do I need to do to get Google running?

Thanks!

google changed a lot since the first howto :P

i haven't yet worked on a working example for current google setup. the only thing that needs looking into is the pattern itself.
