RE: Application gets started twice
Chuck, thank you for your advice and patience :) I have found context element nested inside host element on some tutorial long time ago and that where all the troubles started (It was probably meant for pre 5 Tomcat). Now, following your advice, I have chosen the ROOT approach to be perfectly legal. My last problem is the possibility to make the localhost:8080 (used for mod_jk) also available under localhost:8080/app (as internal endpoints) Is there any legal/simple way to accomplish this? Otherwise I will have put my application back to localhost:8080/app And try to reconfigure mod_jk so that it will show it under mydomain.com instead of mydomain.com/app Thanks, Maciej -- [Chuck] You probably don't want to get rid of the Context elements, but they really should not be in server.xml, at least not on Tomcat 5.0 or newer. Also, if you want a particular webapp to be the default webapp for a Host, it should be named ROOT, not anything else. [Chuck] Again, Context elements should not be in server.xml, and the default webapp for the Host should be named ROOT. Following standard practice makes things much easier; if you were to do that, you could eliminate the Context element altogether, and simply place your webapp in: /usr/local/apache-tomcat-5.5.28/AlfrescoApp/ROOT.war - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
RE: Application gets started twice
Yes, that sounds like a good idea.
For now I have tried something similar that has only one drawback - it is
visible from outside.
Because I didn't want to mess with alfresco endpoints, I have moved alfresco to
regular webapps folder,
Share site is under its own host.
Therefore Share site works directly like this share.domain.com
And for Alfresco I use alfresco.domain.com with auto rewrite to
alfresco.domain.com/alfresco
That is rather fine with me.
Locally Alfresco is available under regular address localhost:8080/alfresco and
Share application can access all the endpoints without any modifications.
Inside HTTPD virtual host for Alfresco I have added:
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/alfresco/
RewriteRule ^/. http://alfresco.tessel.pl/alfresco/ [R]
Once more - big thanks for your support
Regards
Maciej

Since you want this to be effective on port 8080 (httpd not involved), you can
use the rewrite filter:
http://tuckey.org/urlrewrite/
Alternatively, you could install a dummy webapp at either ROOT or app that
simply forwards all requests to the correct one.

RE: Application gets started twice
Thank you for your time so far! And sorry for a long mail this time :) Because I had some other problems with missing libraries I have decided to get a new installation of Tomcat from apache.org - It solved many problems as compared to Centos yum installation. I have a script that will start it as a service under tomcat account. It is not that easy for me to get rid of Context element as when I do that, my mod_jk stops working I can use it like mydomain.com/alfresco but not mydomain.com When I add Context element that points directly to alfresco, it works fine (mydomain.com). Mikolaj wrote: move webapp to folder different than webapps and update docBase Well, that alone did not fix my problem, I believe What is needed additionally is deployOnStartup=false - does this option set to true deployes only to default location? (not the one specified in context?) Chuck wrote: docBase should point to some directory or .war file directly *underneath* the appBase directory. I'm confused as documentation says: When using automatic deployment, the docBase defined by an XML Context file should be outside of the appBase directory. If this is not the case difficulties may be experienced deploying the web application or the application may be deployed twice. Finally, note that if you are defining contexts explicitly, you should probably turn off automatic application deployment. Otherwise, your context will be deployed twice each, and that may cause problems for your app. Taking all of that into account, I have created this HOST definition, and I copy unpacked WAR manually to docBase dir. Host name=localhost debug=0 appBase=/usr/local/apache-tomcat-5.5.28/AlfrescoApp unpackWARs=true autoDeploy=false xmlValidation=false xmlNamespaceAware=false deployOnStartup=false Context path= docBase=/usr/local/apache-tomcat-5.5.28/AlfrescoDocBase/alfresco/ Aliasalfresco.domain.com/Alias /Host Host name=share.tessel.pl debug=0 appBase=/usr/local/apache-tomcat-5.5.28/ShareApp unpackWARs=true autoDeploy=false xmlValidation=false xmlNamespaceAware=false deployOnStartup=false Context path= docBase=/usr/local/apache-tomcat-5.5.28/ShareDocBase/share/ Aliasshare.domain.com/Alias /Host My virtual host for Apache looks like this: VirtualHost *:80 ServerName alfresco.domain.com DocumentRoot /usr/local/apache-tomcat-5.5.28/AlfrescoDocBase/alfresco #DirectoryIndex index.jsp Alias /alfresco /usr/local/apache-tomcat-5.5.28/AlfrescoDocBase/alfresco JkMount /* alfresco_wrk JkUnMount /images/* alfresco_wrk JkUnMount /css/* alfresco_wrk JkUnMount /scripts/* alfresco_wrk JkUnMount /yui/* alfresco_wrk JkUnMount /*.gif alfresco_wrk JkUnMount /*.jpg alfresco_wrk JkUnMount /*.html alfresco_wrk Options FollowSymLinks Directory /usr/local/apache-tomcat-5.5.28/AlfrescoDocBase/alfresco AllowOverride None Allow from all /Directory Directory /usr/local/apache-tomcat-5.5.28/AlfrescoDocBase/alfresco/WEB-INF/ AllowOverride None deny from all /Directory Directory /usr/local/apache-tomcat-5.5.28/AlfrescoDocBase/alfresco/META-INF/ AllowOverride None deny from all /Directory /VirtualHost Final questions: Is this configuration reasonable, or is it a total mess? :) Can I be sure that applications will not get started twice now? Can you please suggest best solution so that application Alfresco that is now available under http://localhost:8080/ would be at the same time available under http://localhost:8080/alfresco ? This is needed for multiple endpoints that Share site refers to. Thank you!

RE: mod_jk problem related to multiple hosts on Apache and Tomcat
Well Andre, you are right, but when I started reading what is the easiest way to make Tomcat available on port 80 (under Centos 5.3) the most common answer was: use Apache HTTPD. Other solutions looked even more complicated as: 1 - Ports below 1024 are available only to root user, and I wanted to run Tomcat under default Tomcat user 2 - I have removed aliases and exclusions from host configurations and left parts relevant to my question, so not everything will be served by Tomcat. 3 - The applications that I'm using have multiple endpoints defined (more than 10 I believe) in different configuration files, and as far as I know it might be the case that not all of them are configurable. Because of that I still need localhost:8080 to serve the same application. This is going to be solved in some future releases of Alfresco so it is going to be possible to set main endpoint as just one configuration value. 4 - I can still use Apache HTTPD to host other applications on that server, that are PHP based. (I know you can make PHP work on Tomcat somehow, but I believe it is recommended or advised to run PHP on Apache HTTPD if possible?)

Application gets started twice
Hi, I couldn't find anything related to my configuration problem. I have Alfresco application installed under webapps/alfresco. The host looks like this: Host name=localhost debug=0 appBase=webapps unpackWARs=true autoDeploy=false xmlValidation=false xmlNamespaceAware=false Context path= docBase=/var/lib/tomcat5/webapps/alfresco/ Aliasalfresco.mydomain.com/Alias /Host When I look at the application log, or catalina.out I can see, that the application is started twice. (there are two application started entries) That happens for each restart of Tomcat... (alias is used for my Apache HTTPD connection, I use Tomcat5, Centos 5.3) Thanks for your great support!

mod_jk problem related to multiple hosts on Apache and Tomcat
Hello, I have a mod_jk problem related to multiple hosts on Apache and Tomcat My setup is Centos 5.3 + Apache HTTPD 2.2.3 + Tomcat 5 httpd.conf contains (Just before section 3) Basic mod_jk directives. At the end it contains two virtual hosts: (all sections are placed in proper files, but I have grouped them to make it easier to read) VirtualHost *:80 ServerName share.domain.com DocumentRoot /var/lib/tomcat5/ShareApp/share/ Alias / /var/lib/tomcat5/ShareApp/share JkMount /* share_wrk Options FollowSymLinks /VirtualHost Worker file defined: worker.list=share_wrk worker.share_wrk.port=8009 worker.share_wrk.host=share.domain.com worker.share_wrk.type=ajp13 worker.share_wrk.lbfactor=1 Tomcat host: Host name=share.tessel.pl debug=0 appBase=/var/lib/tomcat5/ShareApp unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Context path= docBase=/var/lib/tomcat5/ShareApp/share/ Aliasshare.domain.com/Alias /Host - VirtualHost *:80 ServerName alfresco.domain.com DocumentRoot /var/lib/tomcat5/webapps/alfresco Alias /alfresco /var/lib/tomcat5/webapps/alfresco/ JkMount /alfresco/* alfresco_wrk Options FollowSymLinks /VirtualHost Worker file: worker.list=alfresco_wrk worker.alfresco_wrk.port=8009 worker.alfresco_wrk.host=localhost worker.alfresco_wrk.type=ajp13 worker.alfresco_wrk.lbfactor=1 Tomcat Host Host name=localhost debug=0 appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Context path= docBase=/var/lib/tomcat5/webapps/ Aliasalfresco.domain.com/Alias /Host - Problem description: Share site has dedicated host in Tomcat and is linked to dedicated host in Apache - it works perfectly. By typing address like share.domain.com I get the proper index document processed by Tomcat (from the root of the app: /index.jsp) Alfresco site on the other hand is located in the Tomcat Localhost subdirectory /alfresco (webapps/alfresco/index.jsp) When I use this config: JkMount /* alfresco_wrk I can access this site by typing alfresco.domain.com/alfresco but that is not what I need :( (I want direct access without /alfresco) So when I change config to point directly into alfresco root: JkMount /alfresco/* alfresco_wrk And navigate to alfresco.domain.com I get unprocessed JSP file (displayed as text) so it looks like it was not passed to Tomcat? (But I ended in a proper place, because index.html is displayed properly by Apache itself) I can’t move alfresco to separate site as I need acees to it locally via localhost:8080/alfresco address.

RE: mod_jk problem related to multiple hosts on Apache and Tomcat
Thank you both for your support! You are absolutely right. My thinking (rather unexperienced, because this is my first month with linux / tomcat) was that by setting: docBase=/var/lib/tomcat5/webapps/alfresco alfresco would become root of localhost (as it actually does?) and therefore would be not accessible via http://localhost:8080/alfresco (but it still is!) As I have said, this address is needed for Share site as changing endpoints does not always work I beleive this solves my problem for now - I will have to do some test tomorrow, but looks promising! What I still don't know, how to achieve that sort of functionality for many hosts using only localhost. Example: a_domain.com - localhost:8080/app1 b_domain.com - localhost:8080/app2 As opposed to the solution that I have now: a_domain.com - localhost:8080/app1 b_domain.com - host2:8080/app2 Well, I would have to think it over tommorow as its almost midnight in country! :) Once more, thank you very much for pointing out my mistake! ___ From: Tsirkin Evgeny [tsir...@gmail.com] Sent: Wednesday, October 07, 2009 8:50 PM To: Tomcat Users List Subject: Re: mod_jk problem related to multiple hosts on Apache and Tomcat What Chuck means is that you need docBase=/var/lib/tomcat5/webapps/alfresco On Wed, Oct 7, 2009 at 8:51 PM, Caldarale, Charles R chuck.caldar...@unisys.com wrote: From: Maciej Zabielski [mailto:m...@tessel.pl] Subject: mod_jk problem related to multiple hosts on Apache and Tomcat Tomcat Host Host name=localhost debug=0 appBase=webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Context path= docBase=/var/lib/tomcat5/webapps/ Aliasalfresco.domain.com/Alias /Host I can't advise you about the httpd-related stuff, but the above is clearly wrong.
