Hi,
when I compile my classes and generate the rmi-stubs, I get the following exception:

java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused: connect

I get the exception on 3 different servers (WIN and UNIX).
Even when I try to start the program with older sourcefiles (that worked one year ago) it's the same.

I tried j2re1.4.2_05 and ..._09.
Who can help me??

You havent started rmiregistry or the naming server where you want to bind the stub.

Hi, you we're right.
Because I get the exception after a few hours, I commented it out and forgot to take the comments away...
Thank you!

But do you have any idea, why the rmiregistry might crash after a few hours?
My program runs a few hours and gets the java.rmi.ConnectException.
And we have to restart the program.

Hi,

Because the rmiregistry starts and the programs run correctly intially, I do not think there is any problem with the Java setup or the program.

This seems more like a problem with your network or local sys. Does crashing occur at any particular time? Probably there is some job scheduled that interrupts rmiregistry.

I guess this has more to do with your local sys or network. Try troubleshooting. There seems to be no problem from the java side of it.

But it's strange that only with the newer mysql-database 4.1.13 this error occurs. With two older mysql-versions (4.0.17 and 3.x.x) the program (rmiregistry?) doesn't crash.
So we had to return to the older database.and everything works fine.
 
I agree. Here's the link: http://aspose.com/file-tools
