I've had some more thoughts about this and I believe that we don't need
to go that far. We only have to make sure that all servlets, filters and
listeners that we inject are being rewritten so that they get wrapped by
their "Reloading*" equivalents, e.g. see the dispatcher servlet:
<servlet>
<servlet-name>DispatcherServlet</servlet-name>
<display-name>DispatcherServlet</display-name>
<description>Cocoon blocks dispatcher</description>
<servlet-class>org.apache.cocoon.tools.rcl.wrapper.servlet.ReloadingServlet</servlet-class>
<init-param>
<param-name>servlet-class</param-name>
<param-value>org.apache.cocoon.servletservice.DispatcherServlet</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
Carsten added the code that rewrites a web.xml in order to use the
shielding stuff, see
org.apache.cocoon.maven.deployer.WebApplicationRewriter.shieldWebapp.
It shouldn't be too difficult to use it for our purpose too.
To be honest, I don't get most of what you're saying. Do you propose
to write a wrapper for each and
every Filter one intend to use?
No, we already have those wrappers and we need only _one_ of them per
type (servlet, filters, listeners). See the example above: The
DispatcherServlet isn't loaded directly. Instead,
org.apache.cocoon.tools.rcl.wrapper.servlet.ReloadingServlet gets the
parameter servlet-class with the value of the "wrapped" servlet passed.
This way the classloader is injected.
I *believe* (though I'm not 100% sure) that the problem you are facing
now is that your acegi filter isn't wrapped and bypasses the reloading
stuff.
Was a nice try :-( I've wrapped the Acegi-Filter as the other filter in the
web.xml but still getting:
java.lang.IllegalStateException: BeanFactory not initialized or already closed
- call 'refresh'
before accessing beans via the ApplicationContext

org.springframework.context.support.AbstractRefreshableApplicationContext.getBeanFactory(AbstractRefreshableApplicationContext.java:120)

As you can see it still happens with the ReloadingServletFilter :-(
_I'm stuck now!_
_There is nothing working for me anymore_
_I cannot run any of my blocks anyhow_
I will provide a configuration parameter that switches of reloading.
