Subject RE: Tomcat, Apache and mod_jk configuration
Date Fri, 20 Oct 2006 14:05:33 GMT
I'm trying to do a similar setup as well and I'm using just about the same configuration as
shown below (I've attached my configs).  But I'm having one big issue:  when I try to do a
hot redeploy of my webapp, I do not see the changes at http://rtv.myhost.com unless I restart
Tomcat.  BUT, I do see the changes immediately, if I go to http://10.2.1.100:8080/rtv.

Any advice as to what I'm doing wrong would be very much appreciated as I've been banging
my head on the desk for some time about this issue.

The only big difference I see in the configs is that I'm pointing my apache virtual host's
documentRoot to the same path as the webapp.  If I don't do that, none of my static pages
(.css, .js) get served properly, so I don't think that it's the problem.

Thanks,
Josh


Apache config:

<VirtualHost *:80>
    ServerName rtv.myhost.com
    ServerAlias www.rtv.myhost.com
    DocumentRoot /usr/local/tomcat/webapps/rtv
    DirectoryIndex index.jsp index.html
    ErrorLog logs/rtv. myhost.com-errorlog
    CustomLog logs/rtv. myhost.com-accesslog common
 
    <Directory "/usr/local/tomcat/webapps/rtv">
        Options +FollowSymLinks
        Order allow,deny
        Allow from all
    </Directory>

    #DENY ACCESS TO WEB-INF and META-INF
    <Location "/WEB-INF/*">
        AllowOverride None
        deny from all
    </Location>

    <Location "/META-INF/*">
        AllowOverride None
        deny from all
    </Location>

    #ROUTE ALL JSP AND SERVLETS TO THE mod_jk WORKER
    #These extensions are specified in /etc/httpd/conf.d/jk.conf file
    JkMount /*.do router
    JkMount /*.jsp router
</VirtualHost>

Tomcat config:

<Host 
    name="rtv.myhost.com" 
    appBase="/usr/local/tomcat/webapps/rtv" 
    unpackWARs="true"
    autoDeploy="true" 
    xmlValidation="false" 
    xmlNamespaceAware="false">

    <Context path="" docBase="" debug="" /> 

    <Logger 
        className="org.apache.catalina.logger.FileLogger"
        directory="logs" 
        prefix="rtv.myhost.com_log" /> 

</Host>

Yes it's what I mean,

in your JkMount declaration change

jkMount /struts-dev-1/*.do ajp13
jkMount /struts-dev-1/*.jsp ajp13

By 

jkMount /*.do ajp13
jkMount /*.jsp ajp13

And your server.xml fragment should look this way

<Host name="preprod.skyce.net" appBase=""
	unpackWARs="true" autoDeploy="true"
	xmlValidation="false" xmlNamespaceAware="false">

       <Context path="" docBase="/var/tomcat/webapps/struts-dev-1/" debug="0" />

</Host>

It should works.
