Chris,
I second that.  It's a great book.  You'll need an EJB container
as well and I suggest OpenEJB.  It can be found here:
http://openejb.sourceforge.net

It integrates tightly into Tomcat and is very simple to
install/configure/use.  I'd love to help you out with it if you go that
direction.  Later, Jeremy

is there some sort of connection pooling mechanism built into Tomcat? i was 
looking over the sample server.xml, and it seems that you can specify db

connection pooling or is that something we have to implement on our own.

Site Security Issue

[Chris Shen]

dear fellow developers,

i've got a question for you guys...i've got a auth system that
distributes keys to users once they are authenticated. users can then use
that key as a ticket to get services. now, my question is what do most of
you guys do to make your site more secure? i.e. what would you do to keep
that cookie safe from hackers as it's being passed back and fourth through
the web? our main concerns are trojan horses and packet sniffing. we are
thinking about doing an IP check and perhaps setting up SSL? does anyone
have any ideas/opinions on this? thanks!

Active Directory

[Chris Shen]

i know this is kind of off the topic, but i am trying to write to an Active Directory 
using jndi in jsp. However, i have no idea how the active directory schema works. i am 
just trying to look up users. does anyone have any idea on things such as what the 
base DN should be, objectClass, and so on? thanks!

Question regarding Active Directory/LDAP

[Chris Shen]

i know this is not directly related to tomcat. i am trying to write a LDAP
client in jsp to talk to an active directory. however, i am rather
unfamiliar with the directory structure in active directory. i have one set
up on my machine, but i am having trouble looking up attributes such as the
base DN, CN, and so on. does anyone have any clue how to find this type of
information on active directory?

Re: JSP Include Directive

[Chris Shen HOTMAIL]

when you use the include directive, the code, or the jsp file, is inserted
at compile time...in other words, if you modify the contest of the file
that's being included, in order for the modification to take effects, you
must also re-compile your script that is including the modified file...i
hope that helps...whereas if you are doing a dynamic include, things get
included and dynamically generated at runtime...

Subject: JSP Include Directive


Hi,

According to the JSP docs on Sun website, one can use  to include static content, such as methods that will
be reused from different components of the webapp. I wanted to share a
³securityCheck² method to reuse from each single places where security was
required. I did place my code in a includes.txt that I tried to load from a
couple of JSP pages. However even when placing the jsp include tag, nothing
seems to be done since whenever I try to call securityCheck I get a method
not found error... Is the include directive not supposed to work that way?
How can I achieve this?

Sincerely, Frederick

PS: I tried to misspell the resource URL but the compiler did not notice
anything...

web-inf/classes

[Chris Shen]

this is a bizzare one. i've placed all my classes under the web-inf/classes
with the appropriate class structure and everything, and it was working fine
on my tomcat 3.3. yet, after i migrated it to 4.03, i tried to run it the
first time and compiled it, and i kept on getting:
"org.apache.jasper.JasperException: Unable to compile class for JSP
C:\jakarta-tomcat-4.0.3\work\localhost\webauth\successfulLogin$jsp.java:3:
Package ant.uci.edu not found in import.
import ant.uci.edu.*;"

i did place my class directory ant\uci\edu under web-inf\classes...any
idea???

Re: Tomcat & Apache 2 howto

[Chris Shen]

hey, well, for some reason, my apache 2 skips the error message window.
unlike my apache 1, when i test my setting for apache 2, the DOS prompt just
opens up and closes before i can even read the result message, and hence, i
dont even know what sort of errors i am getting! is there a way to pause
that screen?

Tomcat & Apache 2 howto

I've been able to successfully integrate tomcat 3 and 4 with Apache 1.3 using mod_jk. 
However, I have not been able to get either one of them to work with the latest Apache 
2. I am just wondering if someone can perhaps provide some pointers to my problem. I 
am running on win NT/2k. Thanks!
