Downloaded apache-forrest-0.7.tar.gz and unzipped to my home directory. Set the environment according to the instructions, ran the build, then ran "forrest run" from the main directory, opened a browser, went to localhost:8888/ and got the following error.
Could not find component for role: [org.apache.cocoon.components.modules.input.InputModule/lm] (Key='org.apache.cocoon.components.modules.input.InputModule/lm') Clue, please?
