tRio 0.1.4 Web Problem

I'm running tRio 0.1.4 on Linux box with JReceiver 0.2.5, serving 3 Rios and working well. However I cannot get the web front end going. I'm trying to connect from another machine running IE, using this url: http://192.168.2.1:8090/trio-applet.htm where 192.168.2.1 is the address of my Linux box.

I get Applet.Trio not inited in the IE status bar and the following in the Java Console:

Any ideas?

Hmmm, this looks as if it might be a firewall issue. Only I can't get onto the java web-site to check it out. I'll try again in the morning (UK time) and let you know.

Cheers
Paul

Hmmm, interesting point. My client machine is on a different subnet from my rios. The Linux server is dual-homed on both subnets and is acting as the router between the subnets using straight IP forwarding. There shouldn't be any firewalling going on but it is something for me to check. I've used both ip addresses to connect to the server and get the same Java error on both.

Thanks for the pointer. Hope you can get onto the Java website soon! :-)

Cheers

David

David,

When tRio starts up, you should see one or more lines starting with "binding rmi:" in the tRio console (not the java plug-in console). What do these read?

If they don't show 192.168.2.1 then try adding host-name="192.168.2.1" to the <rmi> element in trio.xml (after the create-registry="true" bit).

Cheers
Paul

Paul and David:

Just FYI I had exactly the same problem, and adding the "host-name=" info fixed everything.

Great program!

Bingo! Thanks guys.

Have trio 0.1.4a4, Jrec 0.2.5, on Win 2k pro box.
I'm trying to run the web front end from an old wireless Windows 95 based Fujitsu Point 510 Web tablet with IE5. Have installed Java 1.4.2 (it suggested Win 98 etc might give better results but didn't say it wouldn't work). Just getting the grey rectangle when running http://192.168.0.2:8090/trio-applet.htm
Has anyone got this running on Win 95? Is it worth me adding host-name="192.168.0.2" to trio.xml or am I wasting my time?

What does it say in the java plug-in console (normally a coffee cup icon in system tray)?

Cheers
Paul

looks like some problems here - any idea what?
Tone

What do you get if you open a command prompt/dos window and type:

echo %PATH%

Cheers
Paul

response to echo %PATH% is C:\WINDOWS;C:\WINDOWS\COMMAND

regarding previous post, I've assumed you're wanting the response from the Win95 table.

I mean tablet!!

Not sure if this'll fix it, but try the java bin directory to your PATH. Not sure how you'd do this in win95, but the result you're looking for is:

C:\WINDOWS;C:\WINDOWS\COMMAND;C:\Program Files\Java\j2re1.4.2_01\bin

Cheers
Paul

I think this is achieved by adding extra path to autoexec.bat, anyway I'll try later & report back. US/UK time zone differences and work making this slow process :-(
Tone

Yup. Work, the curse of the drinking classes (to quote Oscar Wilde).

the path now includes the java\bin, sadly still not working - will post java console info later.

Looks very similar to previous :-(

Tone

And you've rebooted your machine (or done whatever) so that it's picking up the modified path?

yes, I've rebooted. And I've checked where my Java\bin is, and path points there, just as per your previous post. When I start trio-applet.htm, it takes some time to load, but it can't seem to locate the applet (although it doesn't noticably complain), so all I get is grey rectangle.
Am at a loss. It works ok on a win98 laptop I have with no path alteration etc, Anything else I can check?
Tone

Sorry, but I'm starting to suspect that we're at a dead-end here. Is it not upgradable to win98?

Cheers
Paul

I probably will upgrade it. I might try on a different Win95 box first - if I do, I'll report back if it works. In meantime, thanks for all help & a great piece of software.
Tone

Just a quick question - can tRio 0.1.4 work with Java 1.3.0 (which runs on Win95)?
Just clutching at straws...I expect Win98 will be s..l..o..w on my somewhat resource limited tablet.
Tone

Sorry, but I very much doubt it. I have it in mind to write a "lite" version of the web-front end that will run under 1.3.0, but I'm seriously short of free time at the moment.

Cheers
Paul

No worries. I'll upgrade it.
Thanks for all help & your great efforts with the s/w.
