JRun Connector Protocol Error w/ CFMX7 Install

[skelm]

I just performed a new install of Coldfusion MX7 this morning on a server that
previously had Coldfusion MX installed. Whenever I try to access any page I
get the following message.

Server Error
The server encountered an internal error and was unable to complete your
request.
JRun Connector Protocol Error.

Anyone have any suggestions? I have tried reconfiguring the Web Server
Configuration Tool to reconfigure as suggested in the install guide but that
was no help. My version of JRUN.DLL is listing as 4.0.5.25479.

Any help would be greatly appreciated.

I don't know about this but check the following.

In IIS, go to you website, then properties, then home directory, then in
application setting click configuration, then in mappings go to your cfm
extention, and make sure it points to the jrun in your cfusion mx7 folder

That is usually a symptom where the webserver was configured with a different
version of the JRun connector than what is appropriate for the CFMX/JRun
server.

For example, say the webserver is somehow using the old CFMX 6.1 connector to
connect CFMX 7. This would produce that error.

Try unconfiguring the webserver, removing every trace of the connector and
ISAPI filter for the website instance level and the global level. Then be
certain that you are running the wsconfig utility from CFusionMX7 not
CFusionMX in case the former installation of MX is still around.

Turn on JRun connector logging for more information if the problem persists.
