Sample from the book
(Below Questions and Answers are randomly taken from different pages of the book)

37: In order to validate Tomcat, what kind of support is there?


The Tomcat mailing lists are extremely active and contain members of many of the organizations, including contractors available for hire. There are numerous smaller vendors and several large ones, including IBM, HP, Sun, and Novell, who offer Tomcat consulting and support services, including application auditing, environment assessments, and risk analysis.


38: How you can check if you have a validated release?


The PGP signatures are available on all the Tomcat download pages, and can be used to verify if the release really is the signed distribution.


39: How can one know that no one has tampered with the release package?


Users are assured with the help of MD5 that the distribution has not been modified since the Release Manager signed it. Users can run MD5 on their local machine to verify that the digest of what they downloaded is the same as that published in the Apache download pages.


83: What are the causes of memory leaks?


Some of the most common causes of memory leaks are:

a) Static variables

b) Thread local variables

c) Poorly implemented data structures


84: Is it possible that Apache can steal favorite site's Internet address?


No it is not possible at all.


85: Why am I getting spam mail from the Apache site?


No marketing spam originates from the Apache site. The mail that comes from the site goes only to addresses that have requested to receive the mail.


86: Explain "regular expressions".


Regular expressions (aka "regex"s) are useful in Apache because they let you apply certain attributes against collections of files or resources in very flexible ways - for example, all .gif and .jpg files under any "images" directory could be written as /images/.*(jpg|gif)$.



168: I am unable to compile my JSP! Why?


JSP compilation may fail because the environment is not set properly. For example: if required environment variables are not set properly, JSP will not compile.


169: Why is the invoker evil?


Invoker is evil because of no security, no Filters and no init parameters.


191: What are top level components in Tomcat?


Tomcat 5 consists of a nested hierarchy of components. Some of these components are called top-level components because they exist at the top of the component hierarchy in a rigid relationship with one another.


192: What are containers?


Containers are components that can contain a collection of other components.


193: What are nested components?


Components that can reside in containers, but cannot themselves contain other components, are called nested components.
