I'm having a NullPointerException on Hicc. When I visit the place with
a browser, all requests related with the workspace show the same
error.
Any clue on this? I have created the mysql database and configured it
in the conf/jdbc.conf and followed the instructions of the
documentation.
Thanks in advance!
