Default [Apache_Tomcat]: $CATALINA_HOME/webapps/host-manager/manager.xml

Hi there,

I am a newbie to Apache Tomcat. While studying the host-manager application, I found the file $CATALINA_HOME/webapps/host-manager/manager.xml. This file seems to be the configuration file for the manager application (not the host-manager):

<Context docBase="${catalina.home}/webapps/manager" .../>

I wonder what the file is used for? I tried to configure the file but neither manager application nor host-manager application is affected.

Thanks in advance

Wow. You found the manager.xml file under "$CATALINA_HOME/webapps/host-manager/"? Did you also find a manager.xml under "$CATALINA_HOME/webapps/tomcat-docs" or "$CATALINA_HOME/webapps/jsp-examples"? According to the "Professional Apache Tomcat 5" (PAT5) book:

The manager.xml file is located under $CATALINA_HOME/webapps/ for Tomcat 4.1 and under the application base for your host in Tomcat 5.x (e.g. $CATALINA_HOME/conf/Catalina/localhost/). If you have multiple virtual hosts, you need to configure a manager for each virtual host via a manager.xml file.
From my experience, the manager.xml file goes under $CATALINA_HOME/conf/Catalina/localhost/. As an example, here is a default manager.xml:
<?xml version="1.0" encoding="UTF-8"?>

    Context configuration file for the Tomcat Manager Web App

    $Id: manager.xml 565211 2007-08-13 00:09:38Z markt $


<Context docBase="${catalina.home}/server/webapps/manager"
         privileged="true" antiResourceLocking="false" antiJARLocking="false">

  <!-- Link to the user database we will get roles from -->
  <ResourceLink name="users" global="UserDatabase"

This was pulled from a Tomcat 5.5.28 implementation. Look familiar?

Now, according to the "PAT5" book, you need 2 things for proper configuration of the Manager app; manager context entry and deployment descriptor. The manager.xml is the deployment descriptor, but you have to have the Context entry in $CATALINA_HOME/conf/server.xml.

From here, if we want to go any further in figuring out which configurations you need, we would need to know the exact version of Tomcat you are running.

HTH. Let us know.
