Please explain 'Cannot connect to the ConnectionReceiver/Ser
Hi,
I am connecting remotely to the testQueue JMS queue by looking up the QueueConnectionFactory and Queue using JNDI.
Both server and client are on jdk 1.4.0.
The queue do not have any MDB's or other consumers on the queue. I am just sending.
As soon as I start sending I get the following:

I know this has been discussed before, one solution was increasing the number of concurrent sockets. I have only 1 OIL connection and I'm using linux with 32000 file descriptors available. I'm also using 1.4 which was a solution of somebody else.
What I want to know is: What does this error mean? Is the server actually trying to connect back to the client using RMI? or trying to connect somewhere else?
People tend to answer forum messages taking the level of expertise of the original poster into account and not the fact that someday a newbie will try and debug the same problem without the background of the original poster...
