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.

The invoker servlet then loads the requested servlet into the container and executes it. If you look at the contents of the webapp deployment descriptor file, web.

The next version (2.3) of the Servlet Spec will allow something like servlet chaining. It's called "filters." Can I use a Generic SAX/DOM XML parser for Tomcat instead of parser.jar? I tried using Xerces and get class not found errors for sun.xxxx parser during Tomcat initialization.

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.

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.

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.

The simplest way to do this is to rely on the Java extensions framework. Add them to the JAVA_HOME/jre/lib/ext directory. Just copy the files there.

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.

If you can't use the standalone HTTP connectors provided in the Noelios Restlet Engine, you can still use the ServerServlet connector which is an adapter between the Servlet API and the Restlet API.

Another reason iPlanet to Tomcat upgrades are hampered are that Tomcat uses a JSSE keystore for it's server-SSL implementation, whereas iPlanet uses the proprietary (now open source) NSS format. There is no satisfactory upgrade path for iPlanet customers who have invested in SSL certs installed in iPlanet, and none at all where they require client-auth as well. I would like to see JBOSS and Tomcat 4.03 integrated with iPlanet on both Linux and Solaris. I was able to integrate Tomcat 4.
