AW: LogKit - FileRotation Contribution

Hi,

attached is a simple version of a HierarchicalRotateStrategy (also the
name might not be perfect).
It can be initialized with an array of RotateStrategy objects. If the
isRotationNeeded() method is needed this array is queried until all
objects are processed or the first one responds with true.

doh! Good point. 

OrRotateStrategy kinda works ... I think I prefer MultiRotateStrategy. Not 
sure.

Well, it might be irritating but that Strategy runs like this:

     Strategy1 || Strategy2
ie.
     size > 10M || (currentTime - last) > 24hours

Isn't it? Shouldn't it be OrRotateStrategy?

Could you tell us what the exception is? It would be easier to diagnose the 
problem that way.

I don't actually use it at this stage. Eung-ju could you describe it ... or 
even better javadoc it ? ;)

how to set configration data for DataSource?

Posted by umashanker <um...@rics.co.jp>.

I'm writing demo for DataSource block, which will get me JdbcConnection from
the pool.
I'm using
"org.apache.avalon.cornerstone.services.datasource.DataSourceSelector" to
get the DataSourceComponent from the excalibur package.

But i'm finding it difficult to set the configration data for this block.
Phoenix is throws exception at "DefaultSarDeployer".

I have gone through "Developing with Avalon" developer guide and Phoenix
assemblers guide. still i'm not getting how this has to be done.Can any one
please give me the sample configration data for the DataSource block. And
explain how it will work?

See org.apache.avalon.cornerstone.services.datasource.DataSourceSelector and
org.apache.avalon.cornerstone.blocks.datasource.DefaultDataSourceSelector.
DataSourceSelector is ComponentSelector for
org.apache.avalon.excalibur.datasource.DataSourceComponent.

demo for ComponentSelector?

Posted by umashanker <um...@rics.co.jp>.

I am new to Avalon,  and going through excalibur components and cornerstone
blocks.

The demos which are given for phoenix container is working fine.

All the service/blocks are using the ComponentManager-  to load the
components.

Is there any demo service/block which uses ComponentSelector?( for the
DataSource block)

if NO , how to create it?
