Thanks for the info,

Ok I have 512Mb RAM and I expect this java servlet to only be active
with a few transactions per month. So I'll see how I go. If my RAQ4R
suffers then I will have my colo host the java servlet for me and
uninstall Tomcat all together.

Below are the instructions given to me by the company that made the java
servlet, anyone care to help me verify that -

1. I only need to follow the last install heading "Transactor 2000
Installation Servlet Installation" (at the bottom of this long post
SORRY).


-START INSTALL INSTRUCTION PROVIDED-
Below are the links to the rpm files that need to be installed on your
system
with Solaris/Linux links shown where ever possible.

Installing the files on RedHat is a simple matter of 
"rpm -ivh ApacheJServ-1.1.2-1.i386.rpm" for example and you are done

Components to required to enable Apache to run servlets:
1. Install the jdk now called the j2sdk
2. Install Apache JServ module
3. Install jsdk

You can just get the java run time environment instead of point 1 but I
presume you will want to enhance the samples in which case you will need

the complete environment.


Where to download j2sdk (Java Software Development Kit):
--------------------------------------------------------

Standard Page for Solaris/Sparc/Linux/Windows
http://java.sun.com/j2se/1.3/

The RPM file if using RedHat Linux is: j2sdk-1_3_0_02-linux-rpm
available from
http://java.sun.com/j2se/1.3/download-linux.html

How to set up j2sdk

nux/

Where to get download for JServ:
--------------------------------
http://java.apache.org/jserv/dist/

For a RedHat packaged script try: 
http://java.apache.org/jserv/dist/ApacheJServ-1.1.2-1.i386.rpm

How to install Jserv
--------------------
http://java.apache.org/jserv/install/howto.unix_install.html

Where to get rpm for jsdk:
--------------------------
For RPM Specific scripts:
http://rpmfind.net/linux/RPM/solaris/RPMS/i386/jsdk-2.0-3.i386.html
  or
ftp://rpmfind.net/linux/solaris/RPMS/i386/jsdk-2.0-3.i386.rpm


After you have installed these files a Linux RedHat 6.2 system would
require
the following modifications (others listed in the How to files above)

Modify the /etc/httpd/conf/jserv/jserv.properties

Replace this Line (to run Java)
wrapper.bin=/usr/java/jdk1.3.0_02/bin/java
Add This line (Point to the Java packages)
wrapper.classpath=/usr/java/jdk1.3.0_02/jre/lib/ext

And you are ready to run.........................


You should be able to run a sample servlet located in
/home/httpd/servlets/ called
IsItWorking to confirm your installation.


Transactor 2000 Installation Servlet Installation
-------------------------------------------------
Once you have unpacked the TransactorClient.tz file with

tar -xvzf TransactorClient.tz *

You will have 3 directories ext, html, servlets

ext: Copy this file to you Java runtime lib ext folder
An example would be: /usr/java/jdk1.3.0_02/jre/lib/ext/

html: Place these in an appropiate HTML directory such as
/home/httpd/html/transactor
for your testing

servlets: Copy the class files to your Java Servlet location
such as: /home/httpd/servlets
The Java files are provided to give you a jump start in creating
your own servlet implementation using the java Transactor package
supplied.

Todd
