I’m moveing to a new computer and operating system , this may not be the place, but trying to back up on (dvd) all my files picts ,docs ex. But cant seam to find a way to back up my jmri and or decoder pro files, is there a way to back up my decoder settings and roster ??
I’m moving from " vista" to “eight” and I know I seen the info but now that I NEED IT I CANT FIND IT …
any willing to expand on this and please , and if you know the best version of the jmri /decoder pro for win eight I,m interested…Jerr
There is an export all files menu in Decoder Pro but I don’t trust it.
Here is what I do:
On your C: drive there is a folder named JMRI you can copy the entire folder and subfolder to an USB Jump drive. Or you can only copy all the files found under C:\JMRI\Roster to your Jump drive.
Install JMRI on your new computer and paste to your new computer under C:\JMRI or c:\JMRI\Roster whatever copying method used.
Once done go to Debug in Decoder Pro and rebuilt the index.
There is no “best” version of JMRI. You can run whatever is supported by JAVA on your computer. Make sure you have the current version of JAVA, then install whatever version(s) are compatible. There are details on the website about what you need for a specific OS.
The JMRI website has a lot of info on moving to another computer, and various ways of doing it. If you still have trouble, subscribe to their mailing list and ask for help. It is very active so you will get a response quickly.
I still haven’t transferred my roster from the old XP machine to the win7 box. The instructions just don’t make sense.
Lots of folks have JMRI working perfectly well with Windows 8, and on the other hand, some folks get the “Java has stopped working…” error even with Win7.
Evidence points to the error being caused by a hardware or possibly a driver timing condition that Java is unable to handle properly.
It affects other Java applications besides JMRI (Google the error message…), and it seems to be more prevalent with the 64-bit versions of Windows.
But it’s certainly not a given in any particular installation that you’ll encounter the error. I use JMRI with a Digitrax PR3 on a Win7, 64-bit system (a combination supposedly notorious for this problem) with no issues whatsoever.
hmmm, now you got me worried , would it be safe to ASSume that a version of java is on this new wonder of tech ? and would one know how to check that ,search ect
I use it windows 7 and it works just fine (64 bit Pro) with JMRI. However, my new laptop with Windows 8 (yech) cant even open JMRI with my PR3 plugged in…
I know for a fact that with XP I never EVER had any issues with JMRI…nada…why upgrade if it is not nessessary?
went to the JAVA site and used the, verify version on my computer and ofcorse it cant verify that I have Java at all, did all the " search files" that were recommended by Java but no find …JW
ps the plan was to put seven on this new com. but was getting use to the 8 until this , may have to go back to plan and buy win 7 for ALL my computors
I have JMRI loaded on a 64 bit HP WIN7 laptop and on a 64 bit HP Ultrabook laptop. I have no problems. Make sure you have the latest Java on the ,machine(just do a Google search on JAVA UPDATE and download the current stuff). I have the next to most current release of JMRI(R3.2 IIRC) on both laptops and have them attached with a Digitrax PR3(WIN7) and a LocoBuffer USB(WIN8)
Most of the problems I have seen others run into seem to be ‘drivers’ - Digitrax has a special set of instructions for loading their drivers on WIN8. My WIN7 laptop came with Vista and was upgraded when HP had to replace the hard drive. JMRI runs fine on both releases. The Ultrabook came with WIN7 and I had a ‘free’ upgrade for WIN8 - Again, no problems.
Randy gave you the location of the ‘roster’ files, but I think they may be in a different directory if you were running XP - There should be something out on the JMRI web site. The ‘export’ function for the roster still is not got all the code and really does not work(at least from what I have read).
Following the JMRI group on Yahoo - almost every single one of the “Java stopped working” issues on Win 8 (and even Win 7) are interface related - the point being that Java in generally is really not so super awesome as the computing press would have you believe, and one major issue it has is absolutely horrid ability to handle I/O errors. Instead, it just crashes if the dwvice isn’t accessible. If the device has the proper drivers, and JMRI is set tot he correct port, it should be fine. If JMRI is looking to the wrong port though, depsite JMRI itself having error checks that SHOULD bring up the settings window if it failes to find the device on the configured port, more often than not, the JVM just crashes and there’s nothing JMRI can do about it. I can make this happen almost at will, by deliberately making the wrong settings. Yet the same thing in another model railroad interface program, written in other than Java, simply returns an error and gracefully exits.
It wasn;t always like this - JMRI used to work exactly as expected if the port was wrong. Somewhere since Oracle took over management of the Java system, this started happening. Problem is, unless you are running an older OS, you have to use a somewhat newer Java to even get it to install.
This seems to also only happen with USB devices - but since very few computers these days actually have a serial port, that means most everything - either a direct USB device like the PR3, or a USB to serial adapter to plug into another system, like NCE.
It’s easy to say this is really a Windows problem, with their USB drivers, but on the very same hardware, with the very same Windows 7 64-bit, the only way i USED to be able to get JMRI to crash was to yank the USB cable out while it was running. Or neglect to make the setting change to that the computer wouldn’t power off the USB port as a battery saving measure.
ok ALL good info, are we talking operating systems ex.xp,vista,seven ,8 or 32 or 64 bit versions of said operating systems. ? I may be wrong but I think my win eight is 32 bit if it matters but I will verify…
NOTE my old computer was running “vista” and the jmri/decoder pro linked thru a pr3 stand alone and then lately with a digi “Zephyr” for speed matching on a circle a track.
so I will try, as mentioned, to down load latest JAVA then recent bug free jmri/decoder pro, if it fails I will ether go with a downgrade to seven (since you can still find 3-pacs) or I well take the computer back to Costco. But to be honest I’m kinda liken this win 8 with the 2 screens (metro app based & the default windows screen )for news ,sports & weather the metro app based screen is smooth fast and no advertisement … and it doesn’t take long to figure out how to shut down ect . and I’m NOT computer savvy
downloaded java ver 7 update 40 and jmri3.4 but don’t remember how to link the port usb , jmri not finding or looking, tried most of the ports, makes no diff. I shall try the jmri site for ideas…Jerry
oops ,forgot about a driver [:$] nothing on this at jmri but digitrax has great BIG "do not conect to you computer till ! " I guess in windows eight you have to go into settings in safe mode to install driver yada yada , man hope I did’nt mess something up in the program, computer or pr-3 …Ill keep ya posted JW
Dave called it [:(!],got the "java tm platform SE binary has stopped working " error and shutdown every time I hit finish setup…BUT digitrax has a real nice step by step how to install pr-3 driver in win 8, that worked like a champ ! to bad though, thats just 2 hours sleep I’ve MISSED OUT ON tomorrow be another day…JW
Yup, you will get that if there’s an problem with the COM port JMRI is trying to communicate with.
In some cases it’s caused by a timing issue within the USB hardware/driver used for the VCP (Virtual COM Port).
But no driver is obviously a problem, and will give you the same result.
I can produce (and correct) that error in my Win7 64-bit / JMRI / PR3 setup at will - All I have to do is specify the wrong COM port in my preferences, restart JMRI, and the error appears. Specify the correct COM port, restart JMRI, and no error.
That’s because the PR3’s driver is not installed on that “wrong” COM port.
stevert: are you saying I can fix this cause I used the small disk w/drivers by digitrax and the assigned port MATCHED the installed driver port (com-3) ,is this wrong ? BESIDES CONTACTING digitrax ,is there something I,m missing here that I can fix ?
and help me to understand the com-port thing,I assume a com port is plug in or usb port and each one has a # so this new machine has 2 reg (2.0) AND 2 SUPER (3.0) on the back and I ASSUMED each one has a pre assigned # like 1,2,3,4, and I just happened to plug the the usb/PR-3 into the port assigned com-3 or port #3 so when the driver install looked for a “live” port/usb it found the pr3 on port/usb #3 or com -3 … is this close or am I just guessing here ?
