unfortunately, I didn't using virtual host stuff, I used mod_jk.conf
/etc/httpd/conf.d/mod_jk.conf
.....
JkMount /jira/* ajp13
JkMount /jira* ajp13
.....
/etc/httpd/conf.d/workers.properties
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1
and you know, actually the "jira" in tomcat has been removed.
the content of "jira" is available in :
http://192.168.1.102:8082.but no "jira" directory anymore.
thanks for you help!
