[OSGI] test if JDBCPoolComponents are started for all my DS

[ekke]

hi,

have you an idea how I can test if the JDBCPoolComponent.start was
executed for all my Datasources ?

they must be started before I can start my EJB bundles

I can test using ServiceTracker if the jdbcpool-component-factory was
started, but its not enough - if I try to start my EJB bundle before the
Datasources are available, EasyBeans uses standard DS "jdbc"_1 and - of
course - gets an exception because this is not bopund to a JNDI name

thx

ekke

I found a way:

I wait until

ConnectionManager.getConnectionManager(DATASOURCE_NAMES[i])

for all my Data Sources != null

or do you have another idea ?

Currently, I have no other good suggestion.
I think that our components maybe should register another interface than
only EZBComponent (which can be seen as a management interface, with
start/stop, ...): the business interface of the component should be
exposed too, so that it simplify defining dependencies with OSGi...

If you could open an improvement in JIRA, please :)

Writing the mail for ManagedService SLSB, rang a bell for me:
Currently, we also register 1 service per interface, we don't collect
the bean's business interfaces and register 1 service for all.
As you're application is quite big, that maybe explain why you have so
many services ...

WDYT ?

yes, one interface for the @Remote and one for the @Local,
but why so many 'identical' for the same @Remote or @Local ?

that you register a service per each Interface of a SLSB that is OK -
then I can choose the @Remote as ManagedService, add the Riena properties
and use them as Remote Services from Riena Clients

80000 + interfaces for some hundred interfaces ?

Hehe, I did not say there was no bug :)

I was just trying to better understand your context :)

I'll continue this discussion on the right thread :)

and I'm still trying to understand what EasyBeans does ;-)
hope I'll learn much before my application goes productive

thx for all your help and soon answers

additional info

small example with my "sample" unit:

11.08.08 10:11:13 (I) JContainer3.start : Container
'org.ekkehard.sample.dataManager' [7 SLSB, 0 SFSB, 0 MDB] started in 910 ms

7 SLSB - thats OK :-)

56 Services ?
2+4+6+8+10+12+14 = 56 :-)

the service.id is so high, because there were other units initialized before
