I have set up Trio, and JREC on a SUSE 9.0 professional box. I can connect my three rio's to it and play music without a problem. I love it. However when I try to go to the front end the applet begins to load then stalls with just a grey screen. I have tried to connect to the front end using:
ip address:
http://192.168.0.100:8090/trio-applet.htm
Loop back:
http://127.0.0.1:8090/trio-applet.htm

Additional information in JREC Config I have set Rio Music Host to 192.168.0.100 my server

I have taken out the Hosts to allow acess thinking that might be it, I hope to put this back in when I correct the problem.

The one thing I have noticed in the logs is that it can't find
/usr/local/trio-0.1.4.alpha5/docs/favicon.ico
and in fact that isn't in that directory. I have downloaded the version again and extracted it again and it still doesn't show up in there so I don't know what that means.

Thank you for your help, please see below for the log file. I am using trio1.sh to start the process if that matters.

Try editing trio.xml and changing:

<rmi create-registry="true"/>

to:

<rmi create-registry="true" host-name="192.168.0.100"/>

This should work with "http://192.168.0.100:8090/trio-applet.htm". Also, make sure you don't have a Strio-0.1.4.jar in your lib directory (delete it if it's there).

Cheers
Paul

First thank you for the quick response.

However, I changed the trio.xml file, and removed Strio-applet-0.1.4.jar from my lib directory and have the same problem. Do you have any more reccomendations?

One last thing, when I type in the site instead of going through favorites, I read a previous post that this was an issue. It seems to stop loading on:

Loading Class:trio.applet.TRioApplet_Stub...

my log at that point simply shows:

Got http request: GET /trio-applet.htm HTTP/1.1

Thank you again for any help you might have,
Keith

The next step is to see what's coming up on the java console. On windows you see this via the coffee mug in the system tray - I don't know what you'd do in linux.

I set my Java Console to show instead of hide so now I can look at anything I need to I think, can you let me know what to look for?
I changed the console to show errors and used Mozilla web browser instead of Konquer and here is what the error came back as. Boy do I wish I thought of trying another browser first. Sorry about that.

By default, java applets are allowed to create network connections with the server they were loaded from, but nothing else. This is to stop rogue applets doing bad things. And so it's getting "access denied" because it was loaded fro 192.168.0.100 and is trying to connect to 192.168.0.112.

What is 192.168.0.112 on your network?

Also, near the top of the java plug-in console there should be a line some thing like "Parameters. trio-server: ?, rmi-port: ?" - what does this read?

Lastly, please confirm what the "binding rmi:" lines say near the top of the tRio Server output.

Cheers
Paul

I can't find anything on my network that is at 192.168.0.112 so I don't know where this number is coming from is there a way I can hard code the correct number in java?

Here are the parameters at the top of my console:

TRioApplet.init(): null
Parameters. trio-server: 192.168.0.100, rmi-port: 1099
Exporting Remote
Finding remote server

Here is my binding lines from trio1.sh

RMI Registry created sucessfully on port 1099
binding rmi: rmi://192.168.0.100:1099/TRioServerRemote
Creating sockets
creating udp socket. local port: 19680, timeout: 15000

Thanks again for all your help.

Keith

I found the problem, in my Hosts file the computer where everything was loaded was set to 192.168.0.112. I changed it to the correcte ip address and everything is working great. Thanks for the help.
