Update portlets.xreg
Is there a possibility to refresh the portlets.xreg without waiting some
time until the RegistryWatcher does it ? I'm changing the xregs
with another application and after that, changes must be visible
immediately.
Regards
Meik

It will be refreshed in 1-2 minutes..
You can play arround it it,
try add new portlet tag there.. and see what going on..
or for easy, please cut and paste the portlet from portlet.xreg to
local-portlet.xreg..
and try to modify the local-portlet.xreg there..

RE: Update portlets.xreg
Posted by Mark Orciuch <ma...@ngsltd.com>.
Paul,
I am aware of this. However, in reality, this does not appear to work as
advertised. Through my trials and errors, I uncovered some problems with
usage of local-portlets.xreg (see
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=5091). I've worked with
Chris (Kimpton) on this but we got hung up on how this functionality was
intended to work (I believe that he was waiting for some clarification from
Raphael). I know that this is not a high priority item but it's documented
in Bugzilla for whenever someone decides to pick it back up.

Could you be a little more specific in your suggestion. I've been also
trying to understand how the concept of "local-portlets.xreg" works and
every bit of information would be helpful. Thanks!

Re: Update portlets.xreg
Posted by Paul Spencer <pa...@apache.org>.
Meik,
Currently the registry is file based. On Windows the timestamp on the
file has a one minute granularity. Thus, if you change the file in the
first 10 seconds of the minute and Jetspeed reads it, then any
additional changes in during the same minute will not update the
timestamp of the file and Jetspeed will not re-read the file. Also
Jetspeed will write the .xreg files at shutdown using the entries it has
in memory. If you make a change that is not read by Jetspeed BEFORE
shutdown, then the change will be overwritten at shutdown.
The parameter "services.Registry.refreshRate" in JR.p that controls the
refresh rate. Since Jetspeed uses the timestamp of the file to determine
if the file has change, any setting below the granularity of the
timestamp just wastes resources.
Their have been some requests to allow direct population of the
registry, but I have not seen an implementation.

RE: Update portlets.xreg
Posted by Mark Orciuch <ma...@ngsltd.com>.
The patch for addEntry method is available here:
http://nagoya.apache.org/bugzilla/showattachment.cgi?attach_id=830
As far as the remove problem is concerned, when I remove a portlet registry
entry, am I not removing it from registry stored in memory? I can actually
query the registry immediately after removal and entry is not there.
However, when I restart, it comes back. It's been a while since I played
with this. When I get some time, I'll try to verify whether the workaround I
suggested even works. If you do it sooner, I wouldn't mind knowing the
result.

OK. I'm not alone :-) Can you send me your patch ?
I think your other problem is related to the things Paul Spencer
explains in his reply to my question.
He said:
"Also Jetspeed will write the .xreg files at shutdown using the entries
it has in memory. If you make a change that is not read by Jetspeed
BEFORE shutdown, then the change will be overwritten at shutdown. "

Automatic content refresh (FileServerPortlet and WebPagePortlet)
Posted by Mark Orciuch <ma...@ngsltd.com>.
If FileServerPortlet is extending the FileWatchPortlet, then shouldn't it
also support the automatic content refresh when the underlying URL changes?
Was the original intention to have another portlet which would support file
watching capability? What about the WebPagePortlet - it is also extending
FileWatchPortlet yet it does not refresh itself when the underlying URL
changes.
I was able to pinpoint why FileServerPorlet does not refresh itself when
changed (I can provide a patch if it's appropriate). However, for the life
of me, I cannot figure out how to make WebPagePortlet work that way. I
understand that local URLs are treated differently than remote ones and that
remote URLs are refreshed at predefined intervals by the DiskCacheDaemon.
Could someone please comment on whether my observations are correct? Thanks!

RE: Update portlets.xreg
Posted by Mark Orciuch <ma...@ngsltd.com>.
Meik,
Be aware of some outstanding problems with the current CastorRegistryService
when registry is changed programatically. I also have an application which
manipulates portlet registry entries at runtime. It was orignally developed
using 1.3a1 code but when ported to 1.3a2, I started experiencing some
problems. One of the problems has to do with adding new entries (see
Bugzilla Bug 5091). I sumbitted a patch but the fix seems to be a lower
priority right now. Another problem that I ran into has to do with removing
registry entries - they seem to mysteriously come back after the portal is
restarted.
I have inquired about registry refresh capability as well. If I remember
correctly, calling existing refresh method will make any programatic changes
disappear. Quick workaround to your problem would be to work with specific
fragments and explicitly call saveFragment and then refresh immediately.
However, this approach is not recommened by Raphael Luta since the
implementation may change and could become database-based.
I'd like to get involved in getting these problems or shortcomings resolved
but there's a lot of questions I have about how this stuff is intended to
work.
Hope this is related to your issue. Otherwise, kindly disregard it.

Is there a possibility to refresh the portlets.xreg without waiting some
time until the RegistryWatcher does it ? I'm changing the xregs
with another application and after that, changes must be visible
immediately.
