i have a trip in my mind. I want using wicket inside cocoon.
a brief regression on cocoon wicket integration interest.. i'm a
professional free software agile developer. My software factory use
only free software or open source software for all development,
testing and production stack. Our application is essentially based
over cocoon (2.1.9) using a custom framework (around cform and
flowscript, you anyone know was it) for controller development and
client side interface. During this day we have interested to
substitute cform (that is quite noise to development) and i want
introduce the using of wicket instead it ;)
now. I have tried this example using wicket 1.2.6 and cocoon 2.2.
Teorically it must work fine, but i have a trouble (a strange
exception) that i'm not understand. Any other people is interesting in
this trip and want help me to integrate wicket and cocoon?
last but not least, the problem :)
first i have developed a workgin wicket application based on these three file:
. MyWebApplication.java
. HomePage.java
. HomePage.html
this is simplest as possible application that display a message (using
simple label value) in the home page of application.
now using cocoon block archetipe creator, i have make a wicket
application that work as cocoon block. essentially i have create a
file in my wicket application like this:
src/main/resources/META-INF/cocoon/spring/servlet-service.xml
<beans . . . >
<bean id="sitemapServlet" class="org.apache.cocoon.sitemap.SitemapServlet">
<servlet:context mount-path="/" context-path="blockcontext:/wicket-block/">
<servlet:connections>
<entry key="wicketServlet" value-ref="wicketServlet"/>
</servlet:connections>
</servlet:context>
</bean>
<bean id="wicketServlet" class="wicket.protocol.http.WicketServlet">
<servlet:context mount-path="/wicket"
context-path="blockcontext:/wicket-block/">
<servlet:init-params>
<entry key="applicationClassName"
value="SimplestAsPossibleWebApplication"/>
</servlet:init-params>
</servlet:context>
</bean>
</beans>
essentially this file (used by cocoon) declare two bean or servlet
that can be used inside cocoon's sitemap or from http requet. For
instance:
http://localhost:8888/wicket, call WicketServlet and wicket framework
work and response
http://localhost:8888/, call sitemap servlet aka cocoon framework work
and response
now i have create ad hoc sitemap for this application:
src/main/resources/COB-INF/sitemap.xmap
<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0";>
<map:pipelines>
<map:pipeline>
<map:match pattern="message">
<map:generate src="servlet:wicketServket:/" />
<map:serialize type="html"/>
</map:match>
</map:pipeline>
</map:pipelines>
</map:sitemap>
in my mind (i have a serios problem in my mind? :) this is i want:
* i want call cocoon using follow request http://localhost:8888/message
* cocoon match pipeline
* cocoon generate a stream (for example of html) calling wicketServlet
/ aka calling http://localhost:8888/wicket/
* wicket must elaborate the request and return a html content
* cocoon serialize content
but when i try above example in running application i get following
message from cocoon and wicket..

?? wicket try to getLocale from BlockCallHttpServletRequest but it
response with an exception that getLocale is no supported. ??
