Re: Re: smartfrog 3.0.01.003.alpha demo quest ion

Thanks for the tips, they definitely moved me further along than I had been, I 
was indeed trying to run all the components on one 11.23 system (cutst106). 
This didn't quite fly, obviously.

However, not totally out of the woods yet, it would seem.

I tried out the helloworld example1dist to make sure things were working ok 
between distributed systesms, so on cutst106, I made the following changes to 
../helloworld/example1dist.sf:

/**
  * example 1dist creates a generator on hostA and a printer component with id
  * "myPrinter" on hostB
  */

//hostA "foo.hp.com";
//hostB "bar.hp.com";
hostA "cutst088";
hostB "cutst089";

and then ran it with the following command (SFHOME=/smartfrog/dist) from
/smartfrog/dist/src/org/smartfrog/examples/helloworld:

sh sfStart localhost ex1dist ./example1dist.sf

I get the following exception being thrown:

Error during deployment of URL:./example1dist.sf, for component: ex1dist
SmartFrogDeploymentException: HOST cutst106.cup.hp.com:rootProcess:ex1dist 
failed to deploy 'p' component
    cause: java.rmi.ConnectException: Connection refused to host: 127.0.0.1; 
nested exception is:
         java.net.ConnectException: Connection refused


so deploying this on cutst106, and attempting to create the generator and 
printer on cutst088 and cutst089, respectively, but it fails with an odd 
exception...

sfDaemon was running cutst106 at the time.

any ideas why i'm seeing this problem?

Thanks

Alan
