We run Apache as a front-end for Tomcat, using mod_jk. In this configuration, Apache sees all Web requests. It processes some itself, and hands others off to Tomcat for processing. If you would like Tomcat to handle other URL patterns, you need to request us to set that up for you. For example, if you have a servlet-based online store at http://www.yourdomain.com/store, then you probably want Apache to send all URL's of the form /store/* to Tomcat.

Bromethalin, the active ingredient in TOMCAT MOLE KILLER, stops the conversion of food to energy. Moles typically die in their tunnels where they naturally decompose. (Back to top)

Karajan has a thread management system which limits the amount of threads that can be created. When used from Tomcat, the maximum number of threads is already reached, so Karajan cannot create any new threeads. The solution is to increase the maximum number of threads that the manager can create. This is done using the TMMaxThreads system property.

Because we can control the installation and configuration of an Apache web server during install, we use it as the default web server even though Microsoft IIS is usually available on a Windows 2000/XP/2003 platform. Apache also provides a cleaner servlet container through Tomcat. However, we also provide an IIS Plug-in, and you can configure IIS as the web server if you have a requirement to use Microsoft technologies.

Author: Alex Chaffee (http://www.jguru.com/guru/viewbio.jsp?EID=3) The Tomcat Apache HOWTO has been revised and placed on the Tomcat web site. Here's a way to do it: Getting, Installing and starting Tomcat Download Tomcat from here: Get Tomcat Installing and starting Tomcat This is a breeze. It consists of the following steps: Unzip "jakarta-tomcat.zip" to the root drive. The zip automatically makes a "jakarta-tomcat" folder and extracts to it.

First, you must map the request in Apache to Tomcat with the ApJServMount directive, e.g., ApJServMount /myservlet /ROOT Second, you must map that url pattern to a servlet name and then to a servlet class in your web.xml configuration file.

First make sure you have defined the environment variable JAVA_HOME to point to the root directory where you have the JDK installed. Then simply invoke on Windows Then in JDebugTool, select Attach... from the Target menu in the menubar, to display the Attach to Target dialog. On Windows, select the Shared Memory tab, and enter jdbconn in the Shared Memory Name field. On Unix, select the Socket tab, and enter 8000 in the Port Number field.

You can indirectly debug a Tomcat 5.0 JSP, by generating the corresponding Java source file, and then Mounting the corresponding Source Path in JDebugTool. First you will need to attach JDebugTool to Tomcat as described in FAQ #25 above. Then you will need to invoke your JSP to determine where the generated Java source file is created. For example, you would then Mount the following Source Path (see FAQ #1): where mywebapp would be the corresponding name of your web app.

Customized responses to errors and problems Allows you to set up files, or even CGI scripts, which are returned by the server in response to errors and problems, e.g.

Apache has been shown to be substantially faster, more stable, and more feature-full than many other web servers. Although certain commercial servers have claimed to surpass Apache's speed (it has not been demonstrated that any of these "benchmarks" are a good way of measuring WWW server speed at any rate), we feel that it is better to have a mostly-fast free server than an extremely-fast server that costs thousands of dollars.

Apache does not automatically send a cookie on every response, unless you have re-compiled it with the mod_usertrack module, and specifically enabled it with the CookieTracking directive. This module has been in Apache since version 1.2. This module may help track users, and uses cookies to do this. If you are not using the data generated by mod_usertrack, do not compile it into Apache.

Apache version 1.1 and above comes with a proxy module. If compiled in, this will make Apache act as a caching-proxy server.

of Apache 1.3, CGI scripts are essentially not buffered. Every time your script does a "flush" to output data, that data gets relayed on to the client. Some scripting languages, for example Perl, have their own buffering for output - this can be disabled by setting the $| special variable to 1. Of course this does increase the overall number of packets being transmitted, which can result in a sense of slowness for the end user. Prior to 1.

No. You can choose any web server on the market that supports JSP and Servlets (e.g. Sun ONE Web Server, IBM WebSphere, BEA Weblogic and others). We are working closely with a variety of partners to support them in quickly adding JSP and Servlet support to their web servers.

Most likely you forgot that we are using Apache which then passes requests on to Tomcat via mod_jk and there is no mapping in Apache for the new application. Also note that the mappings do not allow multiple wildcards or exclusion lists in a JkMount, so we can do If you have a tomcat installation and you whish to use a servlet to replace noexist documents, and you want to do it using Apache and PHP, then Handle properly the wrong requested URL at the servlet "notFoundHandler".
