Re: Objects inherited in subrequests
sorry, was to quick :(( So I decided to patch the DefaultIncludeCacheManager to work in the same way as the IncludeTransformer does, by setting up the child threads with the same context/environment: // Setup this thread's environment RequestContextHolder.setRequestAttributes( this.session.getRequestAttributes()); EnvironmentHelper.enterProcessor(this.session.getProcessor(), this.session.getEnvironment()); I'll test this out, and if it work's I send in the patch. it does not help. It's the way it's meant to work, but it doesn't. Somehow the ObjectModels in the parallel running JXTemplateGenerators affect each other and we have strange side affects on most of our request. we are digging around, but no ideas any more how to fix it... any help would be appreciated.

Re: multithreaded Content Aggregator migration from 2.1 to 2.2
hi,
we found the problem in DefaultIncludeCacheManager and fixed it. I just
submitted a patch together with some more information on the problem.
see:

thanks for your help.

InheritableThreadLocal [1] might be one solution. But being not able to
clean up a thread is always a problem in web environment. IIRC Spring
used to use InheritableThreadLocal in RequestContextListener, but they
changed it to standard ThreadLocal for that reason.
I don't know if CocoonRunnable mentioned by Grek is another point for
potential changes.

Hello,
we have come across this issue .. i posted it on user mailing list and
some one from there suggested me to post it here since it seems to be
bug in cocoon 2.2 .. its a very crucial issue for us.. we cant upgrade
to 2.2 unless we some how solve or find a work around for this issue ..
we have multithreaded Content Aggregator which is based on the
CIncludeTransformer and it also implements
CacheableProcessingComponent for caching .. it used to work fine for
cocoon 2.1.x but with cocoon 2.2 it gives strange error .. it is
actually a generator and it gives error in the generate method ..
the code where it gives error
// generate...
for (Part part : this.parts) {
if (this.manager.hasService(IncludeCacheManager.ROLE)) {
part.uri = this.cacheManager.load(part.uri,
this.cachingSession);
} else {
this.getLogger().error(
The ContentAggregator: aggregator cannot
find the IncludeCacheManager);
}
}
// aggregate...
StreamPipe streamPipe = new StreamPipe(this.contentHandler);
for (Part part : this.parts) {
streamPipe.firstElement(part.element, this.rootElement,
part.stripRootElement);
try {
System.out.println(ParallelContentAgg.part.uri: +
part.uri);
this.cacheManager.stream(part.uri,
this.cachingSession, streamPipe);
} finally {
streamPipe.lastElement(part.element);
}
}
it gives the following error
Caused by: org.springframework.beans.factory.BeanCreationException:

Hi Imran,
last night i wasted 5 hrs overs this without any success .. i guess
it has something to do with passing the RequestContextListener to
the spring context .. i have initialized the listener in my web.xml

wrong with the cachemanager present in cocoon ?

Grzegorz Kossakowski wrote: Therefore I would like to propose introduction of a new scope called request-inheritable which would allow beans (like ObjectModel) to be inherited but by cloning. What do you think? hmm, just tried to solve that problem and found that in IncludeTransformer it works with threading and parallel processing. Only for the DefaultIncludeCacheManager we are using in our replacement for the aggregator to do parallel aggregation it is broken since version 2.2. So I decided to patch the DefaultIncludeCacheManager to work in the same way as the IncludeTransformer does, by setting up the child threads with the same context/environment: // Setup this thread's environment RequestContextHolder.setRequestAttributes( this.session.getRequestAttributes()); EnvironmentHelper.enterProcessor(this.session.getProcessor(), this.session.getEnvironment()); I'll test this out, and if it work's I send in the patch.

Re: a new cocoon logo?
I've always wondered why the logo isn't a cocoon? that's exactly what I liked about the new logo (Frédéric's). The arragement of the letters let it look like a cocoon (at least a bit). Perheps having a combination of the old cocoon 'logo' and a little cocoon makes it easier to remember (A cocoon with a feather perhaps). At the moment it's not much a logo, it's just a text.

Re: Do we have a powered by Apache Cocoon logo?
Do you have it in vector format? I think we need to create a big and a small version. now for every size, I uploaded the logo again as SVG: http://www.triplemind.com/images/powered-by-cocoon.svg Christoph Bertrand Delacretaz wrote: Le 14 déc. 04, à 20:06, Christoph Gaffga (triplemind.com) a écrit : looks something like http://www.triplemind.com/images/powered-by-cocoon160x48.png than. Thanks, for me this is the closest to our brand image, I like it! I'd only lower the powered by text so that the bottom of the letters intersects with the box, and change the color of the letters to white where they intersect. Do you have it in vector format? I think we need to create a big and a small version. Then, we can maybe vote for an official version of this logo to recommend to our users, I suggest yours in two sizes, and Stefano's, so that people can choose a dark or light color depending on their site's look. -Bertrand
Re: Do we have a powered by Apache Cocoon logo?
some time ago I was also looking for that. Zhe only I found was a build with logo. It was somewhere under cocoon.apache.org or in the wiki.

Note that this vector logo is stored in Illustrator format as misc/graphics/cocoon2.ai - I think, because I cannot open it with my Illustrator 10, it says incorrect operator: 'd0'. -Bertrand

I18nT should have most of catalogue handling code removed, and should not have any catalogue configuration information beside simply specifying the ID of catalogue set it wants to work with: catalogue-set name=foo/ Real configuration of the catalogues should happen within i18n bundle component, probably as: i18n-bundles logger=core.i18n-bundles catalogue-set name=messages catalogue id=messages name=messages location=context://samples/i18n/translations/ catalogue id=menu name=menu location=context://samples/i18n/translations/ catalogue id=tiered name=messages locationcontext://samples/i18n/translations/tiered/location locationcontext://samples/i18n/translations/location /catalogue /catalogue-set catalogue-set name=foo ... /catalogue-set /i18n-bundles This way, catalogue handling part and actual catalogue usage are nicely separated into two independent components (and you can easily overide one of them without touching another) Relevant link to archive: http://marc.theaimsgroup.com/?l=xml-cocoon-devm=107426274218350
