JSP works on Standalone, but not when Implemented with IIS
Hello Tomcat Users:
I have exhausted my resources and need help. I developed a web app that
basically just pulls info from an MySql Database. It works fine on my
machine. I had to set it up to be accessed publically so I configured a
server running Windows2000 server with IIS to run with Tomcat. I assume
that the configuration is correct because the java server pages work for
example
http://support.xtelesis.com/examples/jsp/dates/date.jsp
So I am confused as where the problem lies. For some reason my webapp isn't
pulling the info from mysql. Here is all the info. BTW - I am a NEWBIE :)

<!-- A "Server" is a singleton element that represents the entire JVM,

<!-- A "Service" is a collection of one or more "Connectors" that share
a single "Container" (and therefore the web applications visible
within that Container). Normally, that Container is an "Engine",
but this is not required.
Note: A "Service" is not itself a "Container", so you may not
define subcomponents such as "Valves" or "Loggers" at this level.
-->
<!-- Define the Tomcat Stand-Alone Service -->
<Service name="Tomcat-Standalone">
<!-- A "Connector" represents an endpoint by which requests are received
and responses are returned. Each Connector passes requests on to
the
associated "Container" (normally an Engine) for processing.
By default, a non-SSL HTTP/1.1 Connector is established on port
8080.
You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second
Connector
entry. SSL support requires the following steps (see the SSL
Config
HOWTO in the Tomcat 4.0 documentation bundle for more detailed
instructions):
* Download and install JSSE 1.0.2 or later, and put the JAR files
into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA
(Windows)
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA
(Unix)
with a password value of "changeit" for both the certificate and
the keystore itself.
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are
disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

Persistent
Sessions.
saveOnRestart: If true, all active sessions will be saved
to the Store when Catalina is shutdown, regardless of
other settings. All Sessions found in the Store will be
loaded on startup. Sessions past their expiration are
ignored in both cases.
maxActiveSessions: If 0 or greater, having too many active
sessions will result in some being swapped out. minIdleSwap
limits this. -1 or 0 means unlimited sessions are allowed.
If it is not possible to swap sessions new sessions will
be rejected.
This avoids thrashing when the site is highly active.
minIdleSwap: Sessions must be idle for at least this long
(in seconds) before they will be swapped out due to
activity.
0 means sessions will almost always be swapped out after
use - this will be noticeably slow for your users.
maxIdleSwap: Sessions will be swapped out if idle for this
long (in seconds). If minIdleSwap is higher, then it will
override this. This isn't exact: it is checked
periodically.
-1 means sessions won't be swapped out for this reason,
although they may be swapped out for maxActiveSessions.
If set to >= 0, guarantees that all sessions found in the
Store will be loaded on startup.
maxIdleBackup: Sessions will be backed up (saved to the
Store,
but left in active memory) if idle for this long (in
seconds),
and all sessions found in the Store will be loaded on
startup.
If set to -1 sessions will not be backed up, 0 means they
should be backed up shortly after being used.
To clear sessions from the Store, set maxActiveSessions,
maxIdleSwap,
and minIdleBackup all to -1, saveOnRestart to false, then
restart
Catalina.
