Hi,
In studying the document

<http://wiki.apache.org/cocoon-data/attachments/GT2006Notes/attachments/12-CocoonBlocks.pdf>,
I like to have a real feeling of it. So I try the
cocoon-blocks-fw-sample block, but got no good luck. Can anyone give
me some information on doing this?
One way is to build the trunk an point your webcontainer to
cocoon-dist-samples. It contains all the blocks, including the blocks fw
samples. I haven't tested this approach for a while, so I don't know how
well it works.
Otherwise you can extend the cocoon-webapp pom with a dependency on the
blocks fw sample:
<dependency>
<groupId>org.apache.cocoon</groupId>
<artifactId>cocoon-blocks-fw-sample</artifactId>
<version>1.0.0-SNAPSHOT</version>
</dependency>
and rebuild the cocoon-webapp and start jetty:
$ mvn package
$ mvn jetty:run
then you point your browser to
http://localhost:8888/blocks-test/cocoon-blocks-fw-sample1/test
and the other examples in the block fw samples. The URI above is handled
by some different parts of the system. The servlet context:
/blocks-test
is handled by the DispatcherServlet and configured in the web.xml
http://svn.apache.org/repos/asf/cocoon/trunk/core/cocoon-webapp/src/main/webapp/WEB-INF/web.xml.
Then the block servlets are Spring managed components that are
configured in the blocks,
http://svn.apache.org/repos/asf/cocoon/trunk/core/cocoon-blocks-fw/cocoon-blocks-fw-sample/src/main/resources/META-INF/cocoon/spring/cocoon-blocks-fw-sample-blockServlet1.xml,
etc. Each block servlet definition defines a mount path e.g.
/cocoon-blocks-fw-sample1
Then at last the servlet that is embedded in the the block servlet (e.g.
the sitemap servlet) gets the remaining part of the uri as path info:
/test
Which will be handled by the sitemap in the directory that the block
context url points to (using the blockcontext source that I descriobided
in a mail a few days ago),
http://svn.apache.org/repos/asf/cocoon/trunk/core/cocoon-blocks-fw/cocoon-blocks-fw-sample/src/main/resources/COB-INF/test1/sitemap.xmap.
