Webware for Python

I'd try /usr/local/MyApp/webkit start

This I believe is the recommended way to start the process as a daemon
and you can create a simlink in /etc/init.d named
/etc/init.d/webkit_appname and use that to start and stop the server.

Right, you can find WebKit start scripts for various platforms in
WEBWAREPATH/WebKit/StartScripts. During installation, the start script 
that seems most appropriate is copied to WEBWAREPATH/WebKit/webkit.
If it works for you, you can put a symlink to it in /etc/init.d or 
wherever your start scripts sit. You can then use the "insserv" or 
"service" for activating it as a service.

Thank you, Christoph and Cosmin.

This StartScripts collection is a recent addition, is that right?

The app I am adjusting was built in the old style; it began in the  
0.8 era. Does that change your advice?

Yes, these versions had a single start script WEBWAREPATH/WebKit/webkit, 
which probably needs some minor adaption. Try if "webkit start" and 
"webkit stop" works for you or if you can make it work easily. The newer 
start scripts will probably not work, since they use a few new features 
in the AppServer Launch script like changing the user etc. Maybe you can 
just update Webware (you will need to build a new working directory, and 
copy your contexts over, then you can also use the new start scripts).

The Webware Wiki is running again, and it has a recipe for Cheetah.

Such errors are usually caused by some kind of circular redirection.
When do you get the error, immediately after running the AppServer or
after accessing a particular servlet?

-- Chris

Hi Chris,

I get the error, when I try to access Index.py at working directory
(RIM) by point to http://192.168.1.74:8080/ .

I put my servlets into WorkDir/RIM then I put in ApplicationConfig:
Contexts['RIM'] = 'RIM', and Contexts['default'] = 'RIM'.

thanks

I.e. you are using the built-in HTTP, so it is not a OneShot-adapter
issue. Is there anything special like a redirect in your Index.py? Does
it work with a simple Hello World servlet as Index.py?

-- Chris

Dear Chris,

can you explain more about redirect?
Actually it works with simple servlet, even it works with Webware
Examples such as KidKit Examples. But what is the cause of Maximum
Recursion Exceeded error?

I think we need to recode our old app. :(

thanks and regards,

Webware provides several ways to redirect a request, on the server side 
and on the client side with methods such as forward() or sendRedirect().

I guess your Index.py creates such circular redirects, maybe because the 
handling of absolute and relative URLs has somewhat changed since 
Webware 0.6. Otherwise, the API has not changed much. No need to recode 
everything. If you send me the Index.py that is creating the error, I 
can try to find out what's wrong exactly.

This looks like you're using a very old WebKit version.

The latest version is 0.9.2 and there also have been some fixes in the 
trunk concerning the OneShotAdapter since then. I'll try to push a 0.9.3 
release that will include these fixes.

-- Chris

Yes, we developed the application using Webware 0.6. But, the error I
mentioned happened when I tried to redeploy using Webware 0.9.2. Can I
assumed that the 'MaxServerThreads' key shall be in one of the files?
Can you suggest where is the most possible location of the key? Is is
safe to comment the key?

Your log says:

[Fri Feb 16 16:02:42 2007] [error] [client 202.46.146.180]   File
"/home/rollinter/Webware/WebKit/Application.py", line 104, in

self._instanceCacheSize = self._server.setting('MaxServerThreads'),

This looks like you still have Webware 0.6 installed at
/home/rollinter/Webware/ since the Application.py module of
Webware 0.9.x does not refer MaxServerThreads.

You should install Webware 0.9.2, create a new working directory using 
the MakeAppWorkDir script of Webware 0.9.2, and copy your servlets to 
the correspoding location in the new working dir.

-- Christoph

Chris,

I installed Webware 0.9.2. Then I copied our app under WebKit
directory, because some pages mentioning from WebKit.RIMPages.SomePage
import SomePage.

Then I copy OneShot.cgi to /cgin-bin/ and make:
WebwareDir = '/home/rollinter/www/Webware'

Then I run it:

Now, OneShot looked for appserverpid.txt which doesn't exist.

You should leave the WebKit folder intact since it belongs to the 
Webware installation. Or, copy only your context with the servlets 
(RIMPages) as a subdirectory. But better create your own working 
directory and context using the MakeAppWorkDir script.

Also, OneShot is not really a good choice as an adapter. I recommend 
mod_webkit (see http://www.w4py.org/WebKit/Docs/InstallGuide.html).

just a little bit off topic. But have you checked out 
http://lucene.apache.org/solr/index.html
Its using Lucene technology but you don't have to deal directly
with it. Just send your requests to the solr server and get
the answer.

Example client can be found here
http://svn.apache.org/viewvc/lucene/solr/trunk/client/python/


Kindly regards

Ok, I found the problem. It's nothing serious. The index.py servlet in 
the Examples context redirects to "/Welcome", i.e. to the Welcome 
servlet in the default context. But if you create your own WorkDir, then 
the default context is yours, not the Example context. I changed the 
redirection to the relative path "Welcome", and everything works fine 
now. Seems this bug has been there for years already  ;-)
