Hello,
I'm using cocoon 2.2 and I want to use the servlet service framework to
wrap POST calls to external webapps from within my cocoon webapp (as
suggested in [1]).
As a beginning, I wrote a servlet that just outputs XML like this :
-----
public class WrapperServlet extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException
{
response.setContentType("text/xml") ;
response.getWriter().write("<?xml version=\"1.0\"?>\n<data>POST
!</data>") ;
}
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException
{
response.setContentType("text/xml") ;
response.getWriter().write("<?xml version=\"1.0\"?>\n<data>GET
!</data>") ;
}
}
------
I mount my servlet in my cocoon webapp in my servlet-service.xml
declaration as follows (I'm just using one block) :
------
<bean id="service" class="org.apache.cocoon.sitemap.SitemapServlet">
<servlet:context mount-path="/" context-path="blockcontext:/block/">
<servlet:connections>
<entry key="servlet-wrapper" value-ref="servlet-wrapper"/>
</servlet:connections>
</servlet:context>
</bean>
<bean id="servlet-wrapper" class="WrapperServlet">
<servlet:context mount-path="/servlet-wrapper"
context-path="blockcontext:/block/"/>
</bean>
------
when I directly call the servlet, (eg : GET
http://localhost:8888/servlet-wrapper), I have the response I expect.
But I don't manage to call the servlet from within the sitemap.
The following call :
----
<map:match pattern="servlet">
<map:generate src="servlet:/servlet-wrapper"/>
<map:serialize type="xml"/>
</map:match>
----
returns me exceptions like this :

The question is : I am processing right ?
Thanks in advance.
