macromedia flash flash remoting: I realize an exception trace isn't the best way to ask for help, but I haven't
been able to find any information on this problem.

The code is very simple, just calling a Hello World cfc to get a simple test
running. It works on the local windows CFMX installation without a problem,
but when trying to execute from an AIX server running CFMX through JRun, I get
this error trying to execute a cfc procedure:

I'm getting a stack trace for my test that's very very similar to yours, with
just one line of difference at the top.

Flash Remoting MX (not 2004)
CFMX 6.1 on JRun4, several new instances. The new instances are clones of the
first cfusion instance.
Suse 8.2 Linux
A simple component that returns a timestamp as a string.
A webservice test from CFML that confirms that the CFC can be consumed
remotely.
The component works fine on a CFMX 6.1 server configuration on the same
machine.
The netservices gateway was modified to reflect the host and JWS port for the
server instance
The NetDebugger shows that a connection was established and the methods were
called.
A exception occurs on the server clones, and it references isSingleIP( ).
The following code outputs NO on that server instance:

<cfobject action="CREATE"
type="JAVA"
class="coldfusion.server.ServiceFactory"
name="factory">
<cfset ls = factory.getLicenseService()>
<cfoutput>Is License Single IP? #ls.isSingleIP()#</cfoutput>

The exception thrown from the flash remoting call to the CFC is the following:

java.lang.NullPointerException

I am also stumped. Any help is appreciated.

Someone from Macromedia helped me resolve this. The problem was that the JRun
server had a Flash Remoting EAR having a context root of /flashservices which
is different from and interferes with the Flash Remoting EAR contained in the
ColdFusion server having a servlet mapping patter /flashservices*. The
solution is to delete the FR EAR from JRun's JMC for that server instance and
while allowing FR to operate with the CFMX FR EAR.

LarsVR - you hit the nail on the head! I struggled all day with this (a
perfectly functional CFC that I couldn't call from Flash/ActionScript). As you
stated, I had to go into the JRUN JMC and delete the FlashRemoting EAR
instance. Once that was done, bingo! Thanks for your post - I wish Macromedia
would address this issue somewhere in the CFMX Enterprise Edition documentation
(unless I missed it).
