Re: [C2.0b2] - ComponentManager

2001-10-04 Thread Adrian Geissel 

Hi,

Getting considerably further now with integrating my database access
library - however, next hurdle.

It appears that the pool is not initialized - what need I do to make this
happen? According to the log-file, the
dataasource ComponentHandler has been initialized and added to the
ComponentManager, but there is no mention
of the actual connection pool.

Again, any help is welcomed.
Thanks
Adrian

That worked - now the connection seems to be available through the
ComponentManager
Thanks for your help,

[C2.0b2] - ComponentManager

2001-10-04 Thread Adrian Geissel 

Hi,

We looking at migrating our application from C1.8.2 over to C2.

In C1.x, we used Turbine for connection pooling, and we need to move over to
the Avalon CoponentManager framework.

There was one real advantage in using Turbine, where there is a
singleton-access to the connection-pool, thereby allowing it to be easily
integrated with external code. Basically, we have a tried-and-tested
database access library that takes utilises an internal ConnectionFactory
that calls into Turbine for its connections.

I have not found a similar factory method for accessing either the Cocoon
object, its ComponentManager, or any managed components. Have I missed
something, or is there a preferred approach? A non-singleton access to the
connection pool will require a potentially reasonable coding change.

Also, having a little difficulty in configuring a pooled connection to
PostgreSQL - I've followed the instructions in the 'datasources' document,
but the ComponentManager complains that the named component cannot be found.
I've included the relevant bits from both cocoon.xconf, the calling code
(from within an Action) and log-file extract.

Any and all help will be greatly appreciated,
Many thanks
Adrian
