HOWTO integrate a servlet into cocoon (wiki-howto incorrect?)
Hy;
I tried to add another servlet to the cocoon webapp.
i found a HOWTO in the cocoon-wiki, but it doesn't
work (for me) as expected. I'm shure, the solution
to this is trivial, but i don't see it.
what i want to achieve:
I want to call a servlet and it's output shall be
placed into a pipeline for further processing with cocoon.
I need the servlet in the cocoon context because i want
to keep things simple (maybe a wrong assumption :-))
and i need the session context also within my servlet.
Here is what i did so far:
1.) add the new servlet spec to cocoon/WEB-INF/web.xml:
<servlet>
<servlet-name>Zoro</servlet-name>
<servlet-class>com.saxess.zob.Zoro</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Zoro</servlet-name>
<url-pattern>*internal/app</url-pattern>
</servlet-mapping>
What i want here is:
every request, that ends with "...internal/app"
shall be mapped to the servlet "Zoro"
How can i test, that the servlet is really called and
executed without interfering with the cocoon sitemap?
2.) add a sitemap entry:
<map:match pattern="**/app">
<map:generate src="/metasearch/internal/app"/>
...
<map:serialize/>
</map:match>
what i want here is:
The servlet is called and it's result is streamed into the pipeline
and processed further ...
Unfortunately the system does NOT attempt to call the servlet,
but tries to load a file. i get following exception:
Exception during processing of file:/metasearch/internal/app
I also tried using
<map:generate src="context::/metasearch/internal/app"/>
although i don't uinderstand, what i'm doing there. In fact it also
didn't work ;-(
An now i'm stuck again. OK, people, i promise you, if i get my
app finally working, i will write down all bits and peaces and
donate this to the cocoon documentation , the wiki and whatever
is reasonable.
Any comment would help again...
regards, Hussayn

complete failure to integrate an additional servlet into cocoon
Posted by Hussayn Dabbous <da...@saxess.com>.
Hy;
Does anyone know, if the following Wiki-Howto applies to
cocoon-2.0.3 or does it apply for newer releases only???
http://outerthought.net/wiki/Wiki.jsp?page=IntegrateAServlet
Could someone tell me, if there is a difference between
this notation:
<map:pipeline>
<map:match pattern="**/app">
<map:generate src="/metasearch/internal/app"/>
...
<map:serialize/>
</map:match>
</map:pipeline>
compared to this one:
<map:pipeline match="**/app">
<map:generate src="/metasearch/internal/app"/>
...
<map:serialize/>
</map:pipeline>
Anyway both notations won't work for me.
I am completely stuck after hours and hours of try and
error with my servlet integration ...
My problem is described below. I posted it into the
cocoon-user list, but nobody could help so far.
maybe someone from this list could give me a hint .... please ???

Re: HOWTO integrate a servlet into cocoon
Posted by SAXESS - Hussayn Dabbous <da...@saxess.com>.
Hy again;
Does anyone know, if the following Wiki Howto applies to
cocoon-2.0.3 or does it apply for newer releases only???
http://outerthought.net/wiki/Wiki.jsp?page=IntegrateAServlet
I am still stuck after hours and hours of try and error with
my servlet integration ...
anyone any idea, what might go wrong ?
Could someone tell me, if there is a difference between
this notation:
<map:pipeline>
<map:match pattern="**/app">
<map:generate src="/metasearch/internal/app"/>
...
<map:serialize/>
</map:match>
</map:pipeline>
compared to this one:
<map:pipeline match="**/app">
<map:generate src="/metasearch/internal/app"/>
...
<map:serialize/>
</map:pipeline>
I'm clueless... any comment ???
regards, Hussayn
