            Running The Apache Tomcat 6.0 Servlet/JSP Container

Apache Tomcat 6.0 requires the Java 2 Standard Edition Runtime
Environment (JRE) version 5.0 or later.

Running With JRE 5.0 Or Later

(1) Download and Install the J2SE Runtime Environment (JRE)

(1.1) Download the Java 2 Standard Edition Runtime Environment (JRE),
      release version 5.0 or later, from

(1.2) Install the JRE according to the instructions included with the
(1.3) Set an environment variable named JRE_HOME to the pathname of
      the directory into which you installed the JRE, e.g. c:\jre5.0
      or /usr/local/java/jre5.0.

NOTE: You may also use the full JDK rather than just the JRE. In this
      case set your JAVA_HOME environment variable to the pathname of
      the directory into which you installed the JDK, e.g. c:\j2sdk5.0
      or /usr/local/java/j2sdk5.0.

(2) Download and Install the Tomcat Binary Distribution

NOTE:  As an alternative to downloading a binary distribution, you can create
your own from the Tomcat source repository, as described in "BUILDING.txt".
If you do this, the value to use for "${catalina.home}" will be the "dist"
subdirectory of your source distribution.

(2.1) Download a binary distribution of Tomcat from:

(2.2) Unpack the binary distribution into a convenient location so that the
      distribution resides in its own directory (conventionally named
      "apache-tomcat-[version]").  For the purposes of the remainder of this document,
      the symbolic name "$CATALINA_HOME" is used to refer to the full
      pathname of the release directory.

(3) Start Up Tomcat

(3.1) Tomcat can be started by executing the following commands:

      $CATALINA_HOME\bin\startup.bat          (Windows)

      $CATALINA_HOME/bin/           (Unix)

(3.2) After startup, the default web applications included with Tomcat will be
      available by visiting:


(3.3) Further information about configuring and running Tomcat can be found in
      the documentation included here, as well as on the Tomcat web site:

(4) Shut Down Tomcat

(4.1) Tomcat can be shut down by executing the following command:

      $CATALINA_HOME\bin\shutdown            (Windows)

      $CATALINA_HOME/bin/         (Unix)

Advanced Configuration - Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat
binary distribution shared among multiple users on the same server.  To make
this possible, you can pass a "-Dcatalina.base=$CATALINA_BASE" argument when
executing the startup command (see (2)). In this
"-Dcatalina.base=$CATALINA_BASE" argument, replace $CATALINA_BASE with the
directory that contains the files for your 'personal' Tomcat instance.

When you use this "-Dcatalina.base=$CATALINA_BASE" argument, Tomcat will
calculate all relative references for files in the following directories based
on the value of $CATALINA_BASE instead of $CATALINA_HOME:

* bin  - Only (*nix) and setenv.bat (windows)

* conf - Server configuration files (including server.xml)

* logs - Log and output files

* lib - For classes and resources that must be shared across all web

* webapps - Automatically loaded web applications

* work - Temporary working directories for web applications

* temp - Directory used by the JVM for temporary files (

If you do not pass the "-Dcatalina.base=$CATALINA_BASE" argument to the
startup command, $CATALINA_BASE will default to the same value as $CATALINA_HOME,
 which means that the same directory is used for all relative path resolutions.


There are only really 3 things likely to go wrong during the stand-alone
Tomcat install:

(1) The most common hiccup is when another web server (or any process for that
    matter) has laid claim to port 8080.  This is the default HTTP port that
    Tomcat attempts to bind to at startup.  To change this, open the file:


    and search for '8080'.  Change it to a port that isn't in use, and is
    greater than 1024, as ports less than or equal to 1024 require superuser
    access to bind under UNIX.

   Restart Tomcat and you're in business.  Be sure that you replace the "8080"
   in the URL you're using to access Tomcat.  For example, if you change the
   port to 1977, you would request the URL http://localhost:1977/ in your browser.

(2) An "out of environment space" error when running the batch files in
    Windows 95, 98, or ME operating systems.

    Right-click on the STARTUP.BAT and SHUTDOWN.BAT files.  Click on
    "Properties", then on the "Memory" tab.  For the "Initial environment" field,
    enter in something like 4096.

    After you click apply, Windows will create shortcuts which you can use
    to start and stop the container.

(3) The 'localhost' machine isn't found.  This could happen if you're behind a
    proxy.  If that's the case, make sure the proxy configuration for your
    browser knows that you shouldn't be going through the proxy to access the

    In Netscape, this is under Edit/Preferences -> Advanced/Proxies, and in
    Internet Explorer, Tools -> Internet Options -> Connections -> LAN Settings.
