thanx all for your great help.
I am getting closer...
I adjusted the init code of the wicketapplication class as suggested and
wired the wicket-servlet into the block2-sitemap:
<bean id="com.mycompany.block2.service"
class="org.apache.cocoon.sitemap.SitemapServlet">
<servlet:context mount-path="/block2"
context-path="blockcontext:/block2/">
<servlet:connections>
<entry key="wicketservlet"
value-ref="com.mycompany.block2.wicketapp"></entry>
</servlet:connections>
</servlet:context>
</bean>
<bean id="com.mycompany.block2.wicketapp"
class="org.apache.wicket.protocol.http.WicketServlet">
<servlet:context mount-path="/block2-wicket"
context-path="blockcontext:/block2/">
<servlet:init-params>
<entry key="applicationClassName">
<value>com.mycompany.WicketApplication</value>
</entry>
</servlet:init-params>
</servlet:context>
</bean>
*sitemap:*
<map:match pattern="wicket">
<map:generate src="servlet:wicketservlet:/"/>
<map:serialize type="html"/>
</map:match>
*however, now i get a NPE:*

Re: Integration of Wicket Servlet within C2.2 Block with servlet
service -> Problem
Given the java code and the output I would say that Daniel is correct.
In the init-method of your Application-class you could do:
protected void init() {
super.init();
getMarkupSettings().setStripWicketTags(true);
}
This will remove the wicket:id attributes from the rendered output.
