Accessing a cocoon SourceResolver from another servlet ?

[Laurent Perez <ha...@gmail.com>]

Hi

I would like to access the Cocoon servlet from another running
servlet, basically all I want is to query a sitemap pattern and get a
SAX result out of it. I believe I should use a SourceResolver for
that, I don't want to "fake" some HTTP request to hit that sitemap
pattern.

I think I know how to lookup another servlet under my webapp, but I
don't know what to do once I lookup
org.apache.cocoon.servlet.CocoonServlet. Also, o.a.c.Cocoon has a
createSourceResolver() method, but I'm not sure if this is the right
way.

Could anyone point me in the right direction ?

thanks!

wow. great. I'm already using Spring behind Cocoon, I guess I should
give the trunk a try.. any up-to-date docs on how to build it,
especially with the required maven configuration ?

well, under 2.1.9 I found the CocoonBean helper class, which is what
cocoon-client seems to use. so far so good, its processURI(pattern,
outputstream) method works as expected, but processURI(pattern,
contenthandler) (I need to receive that pattern result thru SAX) does
not, throwing an NPE on every attempt.

I tracked the exception down to
o.a.c.environment.AbstractEnvironment#initComponents() :

this.sourceResolver =
(org.apache.excalibur.source.SourceResolver)this.manager.lookup(org.apache.excalibur.source.SourceResolver.ROLE);

does CocoonBean really support writing to a SAX ContentHandler, or is
my ContentHandler object "badly" initialized ? there's really no
documentation about this helper class :(

thanks,
laurent

If you would like to use cocoon-trunk that is very easy:

ApplicationContext context = 
WebApplicationContextUtils.getRequiredWebApplicationContext( 
servletContext );

SourceResolver resolver = context.getBean( SourceResolver.ROLE );

that's it.

I do not know if there is a possibility to get an internal cocoon 
component in 2.1.x.
