Hello:

I am a new member of this mailing list.  I have been developing in 
Tomcat for about three months now and have produced an application I am 
getting ready to deploy to production.

The application consists of three servlets, as described below:

1. Input servlet which responds to a "get" request and uses xalan to 
merge an xml and an xsl file into an html input screen and then receives 
the post response to create an xml file on the server.

2. Admin servlet which allows an admin person to view the response to 
the first servlet for the purpose of approving the file for processing.  
This also uses xalan to create an htlm approval screen.  Upon approval 
the xml file is merged with an existing larger xml file of previously 
approved responses.

3.  Admin servlet which allows the admin person to "publish" the xml 
data into a seris of html pages which are stored in the servlet 
directory on the server.

A pretty simple system actually.  The html is then available for pure 
html browsing.

My problem is that my sys admin person who needs to deploy this system 
on a production box is concerned that Tomcat cannot be performant enough 
to satisfy the high volume of requests on the server.  He is convinced 
that Tomcat is loaded every time anyone accesses the html, even if they 
do not access the servlets themselves.  I suggested configuring Tomcat 
to use Apache as the html server, and he agreed but came back and said 
the same thing.  Even with Apache as the web server the Tomcat overhead 
kills performance.

I don't think this is right.  I think he is confused.  But maybe I am.  
I need someone to help me understand if he is right, or if Tomcat is 
capable of being used in a production high-volume environment.

One more point.  These servlets must be in a secure environment.  They 
use a Thawte certificate for security.  I thought Tomcat could be 
configured to use a secure certificate fairly simply, but he says 
otherwise.

Any help would be appreciated.  I can refer him directly to someone who 
would like to help him through this if anyone would like to help him 
directly.

Thanks in advance.
