Subject Re: Custom generator not call recycle method
Date Thu, 06 Feb 2014 07:35:36 GMT
Hi Thorsten

   Yes, I supposed you tell me. I developed a new generator very similar 
to WebServiceProxyGenerator of the block cocoon-proxy for to consume 
Rest service, but I needed three modifications:
* the new generator have to be a cache component 
(WebServiceProxyGenerator not implement CacheableProcessingComponent)
* Use Apache HttpComponents 4.2 (WebServiceProxyGenerator use Commons 
HttpClient 3.x and this version have bugs about release connections)
* Use a pool connections (WebServiceProxyGenerator not use pool to 
manage connections and this can be a important improve to performance)

I developed a new class to manage pool and declared it using spring, it 
is seems the easy best way.
Besides if I declared the new generator using spring will be very easy 
to add the pool resource.

I had readed that Cocoon 2.2 can use spring to declare objects and I 
found examples with transformer, so I followed the web page:

The new generator seems work ok, but I checked that it not called to 
recycle method at finished and then, not release connection to pool.

At the end, I had have to added ApplicationContextAware interface to my 
generator to access resource pool declared in spring, and this is 
working fine. Still I have to do some test with apache jmeter to check 
performance but first impressions are good.

Best regards.
