Download the source bundle or grab the source files from Tomcat Git repository (at GitHub).
The docs are in the
webapps/docs subdirectory. They are in XML format and get processed into the HTML documentation as part of the Tomcat release.
The best way is to use jsvc, available as part of the commons-daemon Apache Commons Daemon project.
One Other way is to put Apache httpd with mod_jk before your Tomcat servers, and use ports >=1024 in the Tomcat(s). However, if httpd is not needed for some other reason, this is the most inefficient approach.
Another An other method is to use SetUID scripts (assuming you have the capability) to do this. Here's how I do it.
There are some other methods available, like using
ServletContext.getContextPath() to get the context name of your web application and locate some resources accordingly, or to define
<context-param> elements in
WEB-INF/web.xml file of your web application and then set the values for them in Tomcat context file (
META-INF/context.xml). See https://tomcat.apache.org/tomcat-79.0-doc/config/context.html .
How do I configure Tomcat Connectors?
How do I enable Server Side Includes (SSI)?

How do I install the Administration web app?
- Add a line to your c:\Program Files\Apache Software Foundation\Tomcat 5.5\conf\tomcat-users.xml file so that you have a user who has admin role. For example, add this line just before the last line (containing </tomcat-users>) of the file:
- <user username="admin" password="makesomethingup" roles="admin,manager"/>
- Restart Tomcat.
- Now when you visit _http://localhost:8080/admin_ you should see a page that asks for a user name and password. If you still see the "no longer loaded" error message in your browser, you must either force a full reload of the web page (in Firefox, hold down Shift key while clicking on the Reload button) or just restart your browser completely.
If you start Tomcat by using the standard script files (such as
catalina.sh), this can be done by setting
CATALINA_OPTS environment variable. The recommended way to do so is to create a
setenv.sh file, — read RUNNING.txt for details.
Let say you want to increase it to 256 MB (as you required but make sure you have enough amount of physical memory/RAM and for 32bit system, use no more than 1.0-1.1 GB heap space size ). Set the
CATALINA_OPTS to the value of
-Xms256m -Xmx256m. In some cases it is better to set slightly lower size for
This is simply telling, that the items "jms/MyQCF", and "jms/MyQ" exist, and are instances of QueueConnectionFactory, and Queue, respectively. The actual configuration is in context.xml:
Tomcat Manager web application starting with Tomcat 7.0.58 / 8.0.0 supports a command that outputs a thread dump. (Tomcat 9 documentation, BZ 57261)
StuckThreadDetectionValve valve logs stacktraces of request processing threads that are busy for longer than configured time limit. It is available starting with Tomcat 6.0.36 / 7.0.14. (Tomcat 9 documentation)
3. Build your ContextListener: According to the Tomcat's documentation, a Listener is a a component that performs actions when specific events occur, usually Tomcat starting or Tomcat stopping.. We need to instantiate and load our MBean at Tomcat's start. So we build a ContextListener.java file which is placed wherever you want in your project architecture:
