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.

If what you really want is just to have multiple URLs refer to the same (single) webapp, you have a couple of fairly easy choices: 1) Implement a valve or filter that catches references to the alternate URLs and redirects or forwards them to the primary. 2) Create dummy webapps for the alternate URLs that contain nothing but an index.html page that redirects to the primary. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: symlinks in webapps
Of course you *could* do something to encourage a double deploy and get the desired result. Just make a context xml file named after the second context path and set it's docbase to point to the original webapp's folder. It'd look something like this: Assuming you have this in your conf/[Engine name]/[Host name] directory for the original webapp in webapps/originalWebapp (URL would be http://localhost:8080/originalWebapp): originalWebapp.xml: The second context xml file, named secondInstance.xml (URL would be http://localhost:8080/secondInstance): That should deploy the webapp a second time. Most developers try to avoid that, but you seem to be looking for exactly this kind of thing. --David Claudio Tassini wrote: FYI, If I add several blocks each with a different path , in my server.xml, it seems to work .

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
