As you may have noted, I am not a Tomcat expert so you are probably right. But my app logs in catalina.out when it reads its config files, and when I made a symlink in webapps/ to the same webapp it happened just once, while if I create more contexts blocks in server.xml it loads as many times as are the "instances". Another evidence is that the app create a connection pool of 10 connections to an LDAP server, and with the server just started I have exactly 20 established connections , while I was used to only 10 with the old "method". 1) Implement a valve or filter that catches references to the alternate URLs > and redirects or forwards them to the primary. > I am going to study how to accomplish this.

It seems that with tomcat > 5.0 you can't point a context's docBase to something INSIDE the appBase directory when using context files in conf/[Engine name]/[Host name]/[context].xml . You must add them to server.xml, which is discouraged. -- Claudio Tassini
Re: symlinks in webapps
FYI, If I add several blocks each with a different path , in my server.xml, it seems to work . The problem is that it's discouraged in tomcat's documentation, and anyway it causes my app to start several times, while with a simple symlink I had the same webapp referenced as many times as I wished without multiplying the load on the server (the app starts ldap pools... db pools and so on...).

Re: symlinks in webapps
Don't seem to work. It seems that I can't use a docBase in a context.xml that points to something under the appBase directory, as it's simply ignored and tomcat assumes that the docbase is in /webapps : Sep 6, 2008 6:23:28 PM org.apache.catalina.startup.HostConfig deployDescriptor WARNING: A docBase /opt/webmail-portal-tomcat/webapps/WebMail inside the host appBase has been specified, and will be ignored Sep 6, 2008 6:23:28 PM org.apache.catalina.core.StandardContext resourcesStart SEVERE: Error starting static Resources java.lang.IllegalArgumentException: Document base /opt/webmail-portal-tomcat/webapps/WebMail2 does not exist or is not a readable directory On Fri, Sep 5, 2008 at 9:05 PM, Caldarale, Charles R < [EMAIL PROTECTED]> wrote: > > From: Claudio Tassini [mailto:[EMAIL PROTECTED] > > Subject: symlinks in webapps > > > > The goal is to have the same webapp referenced by > > two contexts > > Rather than use symlinks, try using an additional element in > conf/Catalina/[host]/WebMail2.xml: > > > > (Include whatever else is needed from the META-INF/context.xml file, if > there is one.

symlinks in webapps
Hi guys, I'm trying to make a link to an app inside the webapps directory in tomcat 6.0.18 . The goal is to have the same webapp referenced by two contexts, and this worked fine in 5.x . In 6.x, if I make a symlink to a webapp in the webapps directory, the app fails to start: [EMAIL PROTECTED] webapps]# ln -s WebMail WebMail2 [EMAIL PROTECTED] webapps]# ls -l total 24 drwxr-xr-x 11 mwtomcat mwtomcat 4096 Sep 3 10:57 docs drwxr-xr-x 5 mwtomcat mwtomcat 4096 Sep 3 10:57 examples drwxr-xr-x 5 mwtomcat mwtomcat 4096 Sep 3 10:57 host-manager drwxr-xr-x 5 mwtomcat mwtomcat 4096 Sep 3 10:57 manager drwxr-xr-x 3 mwtomcat mwtomcat 4096 Sep 3 10:57 ROOT drwxr-xr-x 6 mwtomcat mwtomcat 4096 Aug 28 15:32 WebMail lrwxrwxrwx 1 root root7 Sep 5 10:06 WebMail2 -> WebMail Sep 5, 2008 10:07:07 AM org.apache.catalina.core.StandardContext start SEVERE: Error filterStart Sep 5, 2008 10:07:07 AM org.apache.catalina.core.StandardContext start SEVERE: Context [/WebMail] startup failed due to previous errors I've tried to add the allowLinking property in context.xml (in the default conf/context.xml and in the META-INF/context.xml of my webapp... just to be sure), but it don't work. I guess that allowLinking allows to make links from inside the context to other places in the filesystem, not to link the context itself to another webapp. I found this very useful in tests environment. Is there a way to achieve this in tomcat 6? -- Claudio Tassini
mod_jk sticky sessions don't work
Hi all! I'm trying to configure mod_jk to handle balance two apache-tomcat instances through an Apache "reverse proxy", i read all the documentation, reference guides and howtos i found but it still doesn't work... Below are some configuration I'm using. The symptoms are that I connect with a browser to a jsp page that prints out the tomcat server that is managing the session, and the relative session ID. Every time I refresh the page, the server name and the sessionID change. I'm using apache httpd 2.2.4 build from source, mod_jk 1.2.23 and apache-tomcat 5.5.23 . Now, this is the httpd.conf (relevant parts only): JkWorkersFile /usr/local/apache2/conf/workers.properties JkShmFile /usr/local/apache2/logs/mod_jk.shm JkLogFile /usr/local/apache2/logs/mod_jk.log JkLogLeveldebug JkLogStampFormat "[%a %b %d %H:%M:%S %Y] " JkOptions +ForwardKeySize +ForwardURICompatUnparsed -ForwardDirectories JkRequestLogFormat "%w %V %T" NameVirtualHost *:80 ServerName portal.domain.it JkMount /status status JkMount /* test The workers.properties: worker.list=test worker.portal1.port=8009 worker.portal1.host=inca-portal1 worker.portal1.type=ajp13 worker.portal1.lbfactor=1 worker.portal2.port=8009 worker.portal2.host=inca-portal2 worker.portal2.type=ajp13 worker.portal2.lbfactor=1 worker.test.type=lb worker.test.balance_workers=portal1,portal2 worker.test.sticky_session=True And, finally, I changed the tomcat server.xml file: Finally, this is a piece of the log saying that he founds a certain session ID, and then he sends the request to the other server which then obviously sets a new JSESSIONID... : [Thu Aug 02 16:52:09 2007] [1970:8] [debug] map_uri_to_worker::jk_uri_worker_map.c (589): Attempting to map URI '/jsp-examples/sesstest.jsp' from 2 maps [Thu Aug 02 16:52:09 2007] [1970:8] [debug] map_uri_to_worker::jk_uri_worker_map.c (601): Attempting to map context URI '/status=status' source 'JkMount' [Thu Aug 02 16:52:09 2007] [1970:8] [debug] map_uri_to_worker::jk_uri_worker_map.c (601): Attempting to map context URI '/*=test' source 'JkMount' [Thu Aug 02 16:52:09 2007] [1970:8] [debug] map_uri_to_worker::jk_uri_worker_map.c (616): Found a wildchar match '/*=test' [Thu Aug 02 16:52:09 2007] [1970:8] [debug] jk_handler::mod_jk.c (2111): Into handler jakarta-servlet worker=test r->proxyreq=0 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] wc_get_worker_for_name::jk_worker.c (114): found a worker test [Thu Aug 02 16:52:09 2007] [1970:8] [debug] maintain_workers::jk_lb_worker.c (543): decay with 2^38 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] wc_get_name_for_type::jk_worker.c (290): Found worker type 'lb' [Thu Aug 02 16:52:09 2007] [1970:8] [debug] init_ws_service::mod_jk.c (607): Service protocol=HTTP/1.1 method=GET host=(null) addr=192.168.10.2name= portal.inca.it port=80 auth=(null) user=(null) laddr=192.168.10.201 raddr= 192.168.10.2 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] service::jk_lb_worker.c (915): service sticky_session=1 id='64EEDE6D4E3C9EF3A2048741CDA5C189' [Thu Aug 02 16:52:09 2007] [1970:8] [debug] get_most_suitable_worker::jk_lb_worker.c (767): searching worker for partial sessionid 64EEDE6D4E3C9EF3A2048741CDA5C189 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] get_most_suitable_worker::jk_lb_worker.c (819): found best worker portal2 (portal2) using method 'Request' [Thu Aug 02 16:52:09 2007] [1970:8] [debug] service::jk_lb_worker.c (935): service worker=portal2 route=portal2 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ajp_get_endpoint::jk_ajp_common.c (2343): acquired connection pool slot=0 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ajp_marshal_into_msgb::jk_ajp_common.c (548): ajp marshaling done [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ajp_service::jk_ajp_common.c (1796): processing portal2 with 2 retries [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ws_write::mod_jk.c (452): written 274 out of 274 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ajp_connection_tcp_get_message::jk_ajp_common.c (1043): received from ajp13 pos=0 len=2 max=8192 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ajp_connection_tcp_get_message::jk_ajp_common.c (1043): 05 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 - [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ajp_process_callback::jk_ajp_common.c (1506): AJP13 protocol: Reuse is OK [Thu Aug 02 16:52:09 2007] [1970:8] [debug] ajp_done::jk_ajp_common.c (2286): recycling connection pool slot=0 for worker portal2 [Thu Aug 02 16:52:09 2007] test portal.inca.it 0.005241 [Thu Aug 02 16:52:09 2007] [1970:8] [debug] jk_handler::mod_jk.c (2238): Service finished with status=200 for worker=test Any help would be REALLY appreciated!
