Tomcat Java Servlets Manager

In many production environments, it is very useful to have the capability to deploy a new web application, or undeploy an existing one, without having to shut down and restart the entire container. In addition, you can request an existing application to reload itself, even if you have not declared it to be reloadable in the Tomcat 5 server configuration file.

To support these capabilities, Tomcat 5 includes a web application (installed by default on context path /manager) that supports the following functions:

* List the currently deployed web applications, as well as the sessions that are currently active for those web apps.
* Reload an existing web application, to reflect changes in the contents of /WEB-INF/classes or /WEB-INF/lib.
* List the OS and JVM property values.
* List the available security roles defined in the user database.
* Remove an installed web application.
* Start a stopped application (thus making it available again).
* Stop an existing application (so that it becomes unavailable), but do not undeploy it.
* Undeploy a deployed web application and delete its document base directory.

Java Servlets
A Java program that runs as part of a network service, typically an HTTP server and responds to requests from clients. The most common use for a servlet is to extend a web server by generating web content dynamically. For example, a client may need information from a database; a servlet can be written that receives the request, gets and processes the data as needed by the client and then returns the result to the client.

Applets are also written in Java but run inside the JVM of a HTML browser on the client. Servlets and applets allow the server and client to be extended in a modular way by dynamically loading code which communicates with the main program via a standard programming interface.

Servlets are more flexible than CGI scripts and, being written in Java, more portable.

Java Servlet technology provides Web developers with a simple, consistent mechanism for extending the functionality of a Web server and for accessing existing business systems. A servlet can almost be thought of as an applet that runs on the server side -- without a face. Java servlets have made many Web applications possible.

Servlets are the Java platform technology of choice for extending and enhancing Web servers. Servlets provide a component-based, platform-independent method for building Web-based applications, without the performance limitations of CGI programs. And unlike proprietary server extension mechanisms (such as the Netscape Server API or Apache modules), servlets are server- and platform-independent. This leaves you free to select a "best of breed" strategy for your servers, platforms, and tools.

Servlets have access to the entire family of Java APIs, including the JDBC API to access enterprise databases. Servlets can also access a library of HTTP-specific calls and receive all the benefits of the mature Java language, including portability, performance, reusability, and crash protection.

BUYING TIP: Before choosing another JSP/Servlets web host - make sure they fully understand JSP/Servlets hosting and can support your Java web app technical inquiries.

Make sure it's not a VPS package - why? VPS is a Virtual Private Server, it's not like getting your own Tomcat server - who is going to support your Java web application on VPS, definitely not the web host - so beware of this! If you have any questions and/or concerns, please email us at support@AldenHosting.com .

Before you choose a Java web hosting provider you should ask yourself "Why is it that only few companies offer Java hosting?" The answer to this common question is simple - hosting Java web applications (i.e. JSP and Servlets hosting) is a complicated task that requires Java expertise in and out. Anyone can offer ASP.NET and/or PHP web hosting but only a few can offer quality Java (JSP/Servlets) hosting.

At Alden Hosting we eat and breathe Java! We are the industry leader in providing affordable, quality and efficient Java web hosting in the shared hosting marketplace. All our sites run on our Java hosing platform configured for optimum performance using Tomcat 5.5.X, MySQL 4.1.x, Apache 2.0.xx and web application frameworks such as Struts, Hibernate, Cocoon, Ant, etc.
