Apache Tomcat

Apache Tomcat is a servlet container developed by the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a “pure Java” HTTP web server environment for Java code to run.

Tomcat should not be confused with the Apache web server, which is a C implementation of an HTTP web server; these two web servers are not bundled together. Apache Tomcat includes tools for configuration and management, but can also be configured by editing XML

Development status

Members of the ASF and independent volunteers develop and maintain Tomcat. Users have free access to the source code and to the binary form of Tomcat under the Apache License. The initial Tomcat release appeared with versions 3.0.x (previous releases were Sun internal releases, and were not publicly released). Tomcat 6.0.20 is the latest production quality release of the 6.0.x trunk (the branch for the 2.5 servlet specification), as of 2009.

Components

Tomcat version 4.x was released with Jasper (a redesigned JSP engine), Catalina (a redesigned servlet container) and Coyote (an HTTP connector).

Catalina

Catalina is Tomcat’s servlet container. Catalina implements Sun Microsystems’ specifications for servlet and JavaServer Pages (JSP). The architect for Catalina was Craig McClanahan.

Coyote

Coyote is Tomcat’s HTTP Connector component that supports the HTTP 1.1 protocol for the web server or application container. Coyote listens for incoming connections on a specific TCP port on the server and forwards the request to the Tomcat Engine to process the request and send back a response to the requesting client.

Jasper

Jasper is Tomcat’s JSP Engine. Tomcat 5.x uses Jasper 2, which is an implementation of the Sun Microsystems’s JavaServer Pages 2.0 specification. Jasper parses JSP files to compile them into Java code as servlets (that can be handled by Catalina). At runtime, Jasper is able to automatically detect JSP file changes and recompile them.

Jasper 2

From Jasper to Jasper 2, important features were added :

JSP Tag library Pooling – Each tag markup in JSP file is handled by a tag handler class. Tag handler class objects can be pooled and reused in the whole JSP servlet.

Background JSP compilation – While recompiling modified JSP Java code, the older version is still available for server requests. The older JSP servlet is deleted once the new JSP servlet has been recompiled.

Recompile JSP when included page changes – Pages can be inserted and included into a JSP at compile time. The JSP will not only be automatically recompiled with JSP file changes but also with included page changes.

JDT Java compiler – Jasper 2 can use the Eclipse JDT Java compiler instead of Ant and javac.

Product features

An overview of the different versions can be found on the Apache website.

Tomcat 4.x

  • Released 2001
  • implements the Servlet 2.3 and JSP 1.2 specifications
  • servlet container redesigned as Catalina
  • JSP engine redesigned as Jasper
  • Coyote HTTP connector
  • Java Management Extensions (JMX), JSP and Struts-based administrations

Tomcat 5.x

  • implements the Servlet 2.4 and JSP 2.0 specifications
  • reduced garbage collection, improved performance and scalability
  • native Windows and Unix wrappers for platform integration
  • faster JSP parsing

Tomcat 6.x

  • implements the Servlet 2.5 and JSP 2.1 specifications
  • support for Unified Expression Language 2.1
  • designed to run on Java SE 5.0 and later
  • support for Comet through the CometProcessor interface
  • is not packaged with an admin console as in past releases

History

Tomcat started off as a servlet reference implementation by James Duncan Davidson, a software architect at Sun Microsystems. He later helped make the project open source and played a key role in its donation by Sun to the Apache Software Foundation. The Apache Ant software build automation tool was developed as a side-effect of the creation of Tomcat as an open source project.

Davidson had initially hoped that the project would become open sourced and, since many open source projects had O’Reilly books associated with them featuring an animal on the cover, he wanted to name the project after an animal. He came up with Tomcat since he reasoned the animal represented something that could fend for itself. Although the tomcat was already in use for another O’Reilly title, his wish to see an animal cover eventually came true when O’Reilly published their Tomcat book with a snow leopard on the cover.

What is Domain Hijacking and how to Prevent it?

Losing a domain is an incredibly frustrating experience for domain owners. This article will help explain how this happens, and how you can keep it from happening to you.

There are three main ways that people lose domain names:

  • An owner allows the domain registration to lapse.
  • A domain is stolen after a hijacker gains access to the registry record.
  • An owner does not keep up-to-date contact information in their record and their record is deleted after the registrar concludes that contact with the owner is not possible.

The good news is that there are steps you can take to keep this from happening to you. The most basic way to avoid losing your domain is to keep track of expiration dates and maintain your contact information. One smart way to do this is to consolidate your domains at one high-quality registrar. This allows you to manage a domain portfolio more easily and comprehensively. But remember, your domain can be deleted if your contact data is out of date. Registrars now have to verify ownership annually.

A second and related tip is to make sure that you are listed as the Administrative Contact. If it is a corporate domain name, then make sure the business owner or a senior executive is the Administrative Contact; this person is authorized to modify the website hosting, the records and he or she can change the domain’s ownership.

Next, it is important to use a paid email account for your Administrative Contact email address whenever possible. Free email addresses can be suspended or deleted. If this happens, you will not receive notices from your registrar for renewal, and someone else could register that email address and then use it to request a domain transfer.

You can also place a registrar lock on your domain. This can help prevent it from being transferred, modified or deleted by a third party. It is also important that you make sure your registrar gives you the ability to unlock your domain at any time without having to call or email them (at DS-Hosting Solutions you can lock/unlock your domain at any time). Otherwise, when you sell a domain name you will have to wait for someone at the registrar to process your request, and then the transfer will take more time and most importantly, it will take more time for you to receive your payment.

It is also important for you to be an educated email user. Never respond to emails that ask you to click on a link or respond without investigating the source and fully understanding the e-mail’s contents. Be especially careful with domain-related emails that look official but are from an unknown source. Contact your registrar to find out what is happening and if the email is from them. Domain hijackers have been known to send out mass transfer requests hoping that a small number of people will actually accept the transfer request. Do not let yourself fall prey to this type of scam.

Another step you can take to make sure you do not lose your domain is putting your registrar on your email list of “approved senders”. This will ensure that you receive emails from your registrar, including the all important registry renewal notices.

Finally, on a related note, it is a good idea to renew your domain early and for long periods of time.

Protect your domains by following these guidelines:

  1. Keep track of expiration dates and keep your contact information up-to date. (Consider domain consolidation.)
  2. Make sure you are listed as the Administrative Contact so that only you can modify the domain record or change ownership.
  3. Try to avoid using free-email addresses.
  4. Make use of registrar locks over which you have control.
  5. Be an educated email user: investigate email senders and email contents.
  6. Place your registrar on your “approved sender” email list and have emails from them go straight to your inbox.
  7. Renew your domain early and for long periods of time.

What is suPHP and what are the benefits?

The earlier version was PHPsuExec but that is quickly being replaced by suPHP and the two do basically the same thing.
suPHP provides an additional layer of protection on servers. It causes php scripts to run under the account username instead of the user ‘nobody’ which is the user that apache/php would run under on a server that is not running suPHP. This feature allows us to more easily track any potential security breaches that come in via insecure php script(s) that a user is running.

suPHP also does away with the requirement of using 777 permissions on directories/files that need write permission. In fact if a directory and/or file has the permission set to (CHMOD) 777 and it is access via a browser, then an internal server error 500 will be generated. The highest level of permissions that a user can use on a suPHP enabled server is 755. This permission setting is sufficient enough for any directories/files that needs to be written to.

The benefit of using suPHP besides better security, is that it will make any PHP applications (most often CMS systems) such as Mambo more user friendly. Case in point: If you upload/install anything via Mambo such as a template on a non-suphp server, then those template files will be owned by ‘nobody’ and you will not be able to edit them manually or even delete them from your account. This ownership issue is done away with suPHP. On a suPHP enabled server, those same template files will be owned by the account username and the account holder will be able to manipulate those files as he sees fit.

No longer do you need to use (chmod) the dangerous file permission of 666 or the folder permission of 777 to make things writable.

The correct permissions should be:

  • Writable Folders: 755
  • Writable Files: 644
  • Files that need to be un-writable: 444

Google Site Map Generator is now running on XeonBD cPanel advanced server

Introduction

Google Sitemap Generator (Beta) is software that improves the ability of search engines to find the content of your websites. Google Sitemap Generator on XeonBD cPanel advanced web server, it analyzes the way that users access content, then builds Sitemap files that contain the URLs that you want search engines to find.

Google Sitemap Generator creates industry-standard Web Sitemaps and automatically submits them to the search engines of your choice. It can also create Sitemaps for Google’s Mobile and Code Search services. In the case of Blog Search, Google Sitemap Generator provides analogous services, but rather than creating Sitemap files, Google Sitemaps Generator collects the URLs and periodically pings them to Google.

This document is an overview of Google Sitemap Generator. For more information about the Sitemap protocol, see http://www.sitemaps.org/. For information about Google-specific functions and Webmaster Tools, see http://google.com/support/webmasters/.

About Google Sitemap Generator

Google Sitemap Generator takes a fresh approach to Sitemap generation. Google Sitemap Generator now monitors our cPanel advanced web server traffic and detects updates to your site whenever a user accesses a new page. The main features of Google Sitemap Generator are:

  • Creation of Sitemaps based on web server traffic, web server logs and web server files.
  • Efficient generation of Web Sitemaps used by many search engines, and of Google-specific feeds for Mobile, Code Search, and Blog Search.
  • Automatic calculation of certain metadata, such as modified time and change frequency.
  • Automatic submission of Sitemaps for Web search.

Sitemap Submission

How are search engines informed about the Sitemaps that Google Sitemap Generator creates?

To submit Web Sitemaps, you have the following options:

Configure Google Sitemap Generator to put the Web Sitemap URL into the robots.txt file, so that the search engine crawler finds the Sitemap file.

Configure Google Sitemap Generator to perform anonymous ping of specified search engines.

Submit the Sitemaps through Google Webmaster Central.

To submit the Google-specific Mobile and Code Search Sitemaps, you use Google Webmaster Central.

To submit Blog Search content, you specify the frequency with which Google Sitemap Generator pings the Google Blog Service. Google Sitemap Generator does not create Sitemap files for Blog Search. Instead, it collects the URLs in its internal database and then sends them to Google.

Dedicated IP Web Hosting

Many of us who is still beginner in web hosting industry didn’t really know what is Dedicated IP/Static IP and does it really important to have dedicated IP for your site ? And is there any difference between having dedicated IP and shared IP. In this article, I will try to explain and elaborate as much as possible so you can have better understanding and decide whether you really need them.

There is a kind of web hosting available that is called dedicated IP web hosting. This is also sometimes called static web hosting. This type of hosting provides a unique IP address that is used exclusively for each individual server space or domain. An individual browsing the Internet can access this information held in any one of these servers by going onto a website with a certain domain name or IP address.

There will be differences in these web hosting accounts depending on whether the IP address is shared or unique. A unique IP address can be bought simply by placing an order with any of the multitude service providers that are available. These web hosting companies will provide a unique IP address after full payment has been made. These websites allow the customer to upload content and other files to their own personal, secure web space.

Dedicated IP web hosting is also ideal for individuals that want to buy the unique IP addresses for a premium price. Some individuals may find that they want to go this route due to the fact that it will prevent the website from collecting spam, a problem that can often occur when using a shared website.

Another advantage to using a dedicated IP web hosting service is that it provides for greater flexibility while also allowing for more complex hosting. Two advantages of this are that they include a private SSL certificate and an anonymous FTP. An SSL certificate provides for online businesses that need to make sure that their customers will have secure transactions. The advantage of an anonymous FTP allows people to share information on the Internet. This will allow anybody who is using the Internet to go to that company’s website and access a public directory by using FTP software.

By gaining a dedicated IP web hosting account and securing a unique IP address, it allows the business owner to have full control over their website. By obtaining a dedicated IP address, it allows individuals or business owners to get the most benefit out of their website. This will result in better search engine results, which are much sought after by businesses.

Dedicated IP addresses are highly valued and are considered as prime Internet real estate. Because of this, there are sometimes high service fees associated with this kind of service. It is possible however to find a web hosting company that will offer dedicated IP addresses for a very reasonable price. If a company thinks that they will benefit the most from dedicated IP addresses, it’s very important that research be done on many different companies. Besides the differences in price that all companies are bound to have, there will also be differences that are dependant on the company’s needs and goals.
