Hi Ivan,
The Google groops mailing list is deprecated; this apache dev@brooklyn
mailing list is the right one.
Currently in Brooklyn, it's only possible to update the catalog
programmatically. Same goes for adding jars to the classpath [1].
Unfortunately, there's not a nice way to drive this from the web-console
or command line.
Currently, restarting Brooklyn is the "safest" option in such cases - if
Brooklyn was started with `--persist auto` then the applications' state
will have been persisted, and it will rebind to the apps (this work is
ongoing to ensure it works with all the entities out there).
Moving forwards, there is work afoot to use OSGi for these exact
use-cases. I expect you'll be seeing a lot of traffic on dev@brooklyn on
this topic soon!
It would be great to get your thoughts on that - either now or when the
OSGi discussion kicks off properly.
There's a lot of interest in this, so I think it should make it into
Brooklyn in the near future.

[1] api/src/main/java/brooklyn/catalog/BrooklynCatalog.java - methods
like addItem() and addToClasspath()
However, these are not used much (and are lacking good unit test
coverage) so treat with caution.

Hi all,
I can see Brooklyn's community groups are DEPRECATED (both for user and
developers). I do not know if it is the appropriate way to ask questions
to the community, but I will do anyway ;)
Questions:
1) Is it possible to update catalog's content (or maybe change the
pointed catalog.xml file) on runtime? (I mean, in the way you want to
update available applications from the catalog just with a "refresh
button" in the while Brooklyn is already launched). As I can see, the
only way to do it is re-launching Brooklyn but it is not a very pretty
solution if applications are already running and they must to be
restarted...
2) Is it possible to add new entities by YAML just specifying the
"*.jar" path? I know it is possible to deploy packaged applications
(*.war files) related to an existing entity type, but I do not know how
to launch an entire application. Something like catalog enables, but by
YAML...
If this is a wrong way to resolve doubts, please let me know how to do
it. And sorry for the inconveniences.
Best Regards
