We are having trouble moving our web site into production. We have
successfully deployed the site within our firewall, but are now trying
to move our web server outside our firewall. Jaguar now seems to be
refusing connections from the other side of the firewall (with the
exception of connecting with telnet to the IIOP port, just to see if the
port had a listener). It has no problem accepting connections from
inside the firewall.

Connecting from a DynaScript page outside the firewall gives the
following error:

Error Message: Exception thrown: org.omg.CORBA.COMM_FAILURE: sxweb4:683-
Connection refused in method CreateComponent of class jagcomp. Unable to
find or create the required component with the given parameters:
"QGCommon/app_login iiop://161.49.21.144:683 jagadmin ". near line 87

Connecting from Jaguar Manager outside the firewall gives the following
error:

Failed To Connect: The server is not running or is unreachable due to
problem with listener or network configuration

A few more details-
Web server: IIS w/ PowerDynamo
Firewall: Checkpoint Firewall 1
Component server: Jaguar CTS 3.0.1

Again, telneting to the IIOP port seems to succeed (although it's hard
to verify because you can't do anything - I am assuming it has succeeded
since no error is generated) but Dynamo and Jaguar Manager fail. From
within the firewall, everything works fine.

Any assistance would be greatly appreciated.

Jim

Jim, I'm fairly certain you have conflicting listeners. ;-)

Well, as it turns out, I did have two listeners trying to listen on the
same port. The first one succeeded and the second one (the IIOP listener
I was concerned about) failed. Thus telnet succeeded because someone was
listening to the port, yet Dynamo failed because it was the wrong
listner.

Are you setting ProxyHost and/or ProxyPort when connecting outside the
firewall? I very vaguely recall there being an issue that you cannot use
Jaguar Manager to connect outside the firewall, which might explain the
difference in messages, but I am not completely certain it wasn't a
misconfiguration on the client's part.
