P.S: I finally can build the cocoon. Now the problem is when I launch:
./build.sh run
jetty starts, but when I point the browser to http://locahost:8888/ (as Stefano suggested) I got:
Not allowed to define mixed content in the element cocoon at file:/home/agallardo/CVS/cocoon/xml-cocoon2/build/cocoon-2.1-dev/webapp/WEB-INF/cocoon.xconf:3:23
I get the same error, but I worked around it by copying my old cocoon.xconf in place of the one provided.
