Re: Custom generator not call recycle method

[Miguel]

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: 
https://cocoon.apache.org/2.2/core-modules/core/2.2/688_1_1.html

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.

Hi

I have to come back to old configuration of generator:

<map:generator label="icmsRest" name="icmsRest" 
logger="es.juntadeandalucia.generation.CustomGenerator"
src="es.juntadeandalucia.generation.CustomGenerator">
      <serverICMS>ip_machine</serverICMS>
      <portICMS>port_machine</portICMS>
<namePool>org.apache.cocoon.generation.HttpPoolManager</namePool>
</map:generator>

Then, HttpPoolManager is a resource defined like spring bean and for 
to use it in my custom generator, I have to implement 
ApplicationContextAware interface. So, in this way, my generator work 
fine and recycle method is called at finish of my generator.


Hi Miguel,

not sure whether I understand, you have it working now?

I think the recyle method is special to avalon and I think spring 
based components do not use this method anymore. Using the "old" 
config tricks c2.2 into using the avalon methods...at least that is 
what its look like.

Hi,

I'm migrating configuration custom generator from Avalon to Spring 
and generator is working well but I have checked that generator does 
not call recycled method when it has finished.

My generator configuration in servlet-service.xml file is:

<bean scope="prototype" 
name="org.apache.cocoon.generation.Generator/customGenerator" 
class="es.juntadeandalucia.generation.CustomGenerator">
      <property name="server" value="${ip.machine}" />
      <property name="port" value="${port_machine}" />
      <property name="parser" 
ref="org.apache.cocoon.core.xml.SAXParser"/>
      <property name="manager" 
ref="org.apache.avalon.framework.service.DefaultServiceManager" />
</bean>

When I used old configuration:

<map:generator label="customGenerator" name="customGenerator"
src="es.juntadeandalucia.generation.CustomGenerator">
    <server>${ip.machine}</server>
    <port>${port_machine}</port>
</map:generator>

then, my generator work all well and execute recycle method when 
generator is finished.

Any ideas?
Thanks.
