Found the cause - Maven starts jetty using wrong (default) port number, see the last line of the log[3]:
2008-10-01 16:11:14.548::INFO:  Started SelectChannelConnector <at> 0.0.0.0:8888

After quick testing at my local computer it looks like settings from MAVEN_OPTS environment variable
are not propagated to jetty:run plug-in. In order to test it try:
cd core/cocoon-webapp
export MAVEN_OPTS="-Djetty.port=8123"
mvn jetty:run

and check at which port jetty listens. If it's not 8123 then we have found a bug and we should
report it to Maven team. If anyone confirms this problem I'll introduce temporary fix so our demos
are online again.

Hi Imran,

Sorry for next delay - this time I'm moving to a new flat.

When it comes to your problem I've looked into sources of JX templates and found:
Attr 1 :${cocoon.request.getParameter('attr1')}<br/>

I believe it should look like:
Attr 1 :${cocoon.request.getAttribute('attr1')}<br/>

After applying this change both parameters and attributes works fine for me. Is there anything else
missing? I would like to start polishing of my patch so it can be applied to trunk.

sorry for that typo .. but for me after changing it to attribute also its still the same .. i mean the fisrt time
the page is loaded the attributes and the parameters are there .. but then when u keep clicking the links
with the parameters most of the time the attributes are missing .. 

on each component at the ends there are links like: 
With Parameter 1 With parameter 1 and 2 With parameter 1,2 and 3 

those are the three links .. and as i said if u keep clicking them most of the time the parameters and the
attributes are missing .. 

without the params also the attribute should always be there .. but if i keep refreshing the page the
attribute is also often missing 

did u change anything except for the changes present in the patch ?
i have the source from your git repo so i think it should be the recent one ..

This is weird. For me this worked yesterday. Only when setting
jetty.port using MAVEN_OPTS Maven ignored that setting.

Which should be the opposite way.

What version of Maven and jetty plugin do you use?

Imran,

It's my time to apologize. I didn't read your previous description carefully enough. Now I could reproduce
your problem which is just a sign of much bigger problem.

IncludeCacheManager uses thread pooling technique which does not play nicely with ThreadLocals, see: http://java.sys-con.com/node/37241

As I said this problem is not limited to the newly introduced Factory for ObjectModel. Servlet Service Fw
and Spring itself use ThreadLocals as well.

I think this is a right time to move this discussion to dev@ list so others can comment. I'll be probably in
favour of removing thread pooling completely but I don't know performance implications at the moment.

hi Grzegorz,

in the article there was something about "Lack of a Standard Thread-Pooling Library " .. now there is a
standard which comes with the JDK .. i don't know if we are using that or not .. but it is possible that it might
take care of the ThreadLocal variables .. just a thought.

should i forward this discussion to the dev mailing list ?
