ConfigAdmin change the files location
Hi
I'm try to use ConfigAdmin to save and load configurations.
The default place of the configurations is under the cache folder and deep
into the ConfigAdmin bundle.
I don't know it is designed like this.
I should suppose to have some pre-defined configuration values,
And when I deliver my software there is no cache folder, how can I put i
into this.
I try to change the configuration location to the felix/conf folder like
this:
felix.cm.dir=../../../conf
But it complains about ".." reference.
I also wondered if I can use the default "config.properties" with
ConfigAdmin
Regards
LongkerDandy

Yes, chances are that there will be a fix as of
https://issues.apache.org/jira/browse/FELIX-2571. But I cannot say, when.

Re: ConfigAdmin change the files location
Posted by LongkerDandy <lo...@gmail.com>.
I read in another thread that the change made by ConfigAdmin will not
propagated back to FileInstall.
Too bad for this.
Is this going to be fixed?
Or I need a another solution?

Yes and no: Yes, FileInstall will not currently write back changes.
There is an enhancement request for this
(https://issues.apache.org/jira/browse/FELIX-2571).
But the ConfigurationAdmin internal persistance file is certainly
written back. But this is not your consumption ;-)

Beware: I suggest you only create a new Hashtable() if getProperties()
returns null (if the configuration is new). For an existing
configuration, I would rather just update the modified properties.

Re: ConfigAdmin change the files location
Posted by LongkerDandy <lo...@gmail.com>.
Hi
Try to using FileInstall and ConfigAdmin together.
I can read the config properties from ConfigAdmin,
But I have problem to write it back.
Both FileInstall .cfg file and ConfigAdmin cache .config filw won't update.
My code is like:
Configuration config =
configAdmin.getConfiguration("xxx.xxx.xxx.xxx");
props = config.getProperties();
props = new Hashtable();
props.put("xxx", "xxx");
config.update(props);
Any clue?
Thanks

Re: ConfigAdmin change the files location
Posted by Christian Schneider <ch...@die-schneider.net>.
Thanks to all who responded.
I am now using fileinstall and config admin together like sugested.
The config file is read by fileinstall and put into a managedservice.
Then I use spring osgi cm support to bring the properties into spring.
For me this works well as I do not need to write back changes at the moment.
Compared to my first solution when I was using config admin directly
this aproach has the advantage that I can use plain properties files.
This is much
better than the cache files from config admin service which have a quite
special syntax.
Thanks

Re: ConfigAdmin change the files location
Posted by Felix Meschberger <fm...@gmail.com>.
Hi,
Just to clarify what the OSGi Configuration Admin Service is all about:
- Allows Management Agents (administrators, tools, whatever) to manage
configuration
- Delivers configuration to interested parties
- Persistently stores configuration
A Configuration basically is just a Dictionary whose keys are strings
(case-insensitive) and whose values are of a limited set of types,
basically primitive types, their wrappers plus Collections or Arrays
thereof. (For the OSGi R 4.3 release it is planed to have more
interesting ways to describe configuration....)
Back to your question: Yes you can use Configuration Admin for your
configuration and yes you can put into the configuration whatever you want.
To manage configuration you have a number of tools at your disposal:
- Use the Web Console allowing for a simple GUI to configure values
(makes use of the Metatype Service to describe configurations)
- Use File Install to provide preconfigured configuration files to
be loaded into the Configuration Admin service automatically.
This tool also recognizes changes to files and thus updates
configuration.
- Do it yourself coding an application using the Configuration Admin
Service API...
IIRC the configuration files processed by File Install are more or less
pure property files.

IMHO yes. We are using this approach too.

AFAIK the specification doesn't tell about the persistence format.
Felix config admin implementation uses *.config and they are not meant
to be edited by hand althought we also do this :-). But the change is
not dynamic - if you edit the config file during runtime, bundle will
not see the changes until config admin bundle restarts.
Other config admin implementations can store data to database or
binary formats....
For managing the configuration you can use Felix Web Console,
http://opensource.luminis.net/wiki/display/SITE/OSGi+Configuration+Admin+command+line+client
or other/your impementation.

Re: ConfigAdmin change the files location
Posted by Christian Schneider <ch...@die-schneider.net>.
Hi,
I am currently also evaluating the config admin service. I ported a
spring application to osgi and now have the problem where to put the
properties files. The property files contain db and jms connection infos.
Is config admin service the right tool for this job?
I already succeeded in creating the config programmatically and using it
in spring with help of the spring osgi config admin support. As
implementation I used the felix cm bundle. What I do not like is that
the persisted files contain additional information compared to the
normal property files. So it is quite difficult to create and change
them by hand. If I only put the original properties into the file I even
get a nullpointer exception.
Is it possible to conffigure felix cm to work with pure propety files
that do not contain additional information or would you recommand
another aproach?
Thanks
Christian

Yes, the default location is the bundle private data area provided by
the framework through the BundleContext.getDataFile(String) method.

You can use and you can change the setup.
BUT: This is not to inject default configuration. This data area must be
configured private to the Configuration Admin service because changes
are expected to only be carried out by the Configuration Admin service.
If you want to provide "default" configuration you might want to
consider FileInstall and provide respective .cfg files. See [1] for more
details.
Hope this helps.
