I have in mind to use the apache webserver as frontend and Jboss as backend. I am trying to install the mod_jk12 by following the link http://www.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss I have compiled the mod_jk module, but wen I start the apache server I get the error Attachning shm:/etc/httpd/logs/jk.shm errno=13 in the mod_jk.log under apache. Does somebody know, what that mean. I know the question is more directed towards Apache than Jboss. But I hope you anyway can help. At least to the correct Apache forum.
