Anyone have any experience with Mysaifu JVM? It is an open source JVM for WinCE.


Dennis

Warning, we use the following super-duper-unreliable-not-guaranteed-to-be-there JVM options:



Other JVMs likely don't have these options, and Ignition's stability is not guranteed on them!

So, Kevin help me understand your message.

Are you saying Ignition is normally used with the Sun/Oracle JRE with those command line options you mentioned?

Or, are you saying if we try to use the Mysaifu with WinCE, then we need to set those command line options?

I was wondering if anybody had even tried Mysaifu to see if Ignition would work with it.

Still looking for a touch panel, WinCE based, configured by the vendor, that could support Ignition.

I guess my preference would be to be able to by a standard product that could have the JRE installed and we just install Ignition. This is looking at Panel Edition as a fallback mode.

Thanks for all your hard work.

We normally use it with the Sun/Oracle JRE and those options set. I don't believe other JRE's even have those options.

Ignition would probably still run, but you would be in uncharted territory because those options affect garbage collection and memory usage/leaks related to soft restarts.

That's what I expected.

Thanks, Kevin.

Linux may still be the best option. I know it will work.

Hi,

I have one application where we would like to put in place some linux based thin clients as part of a redundant controls scheme for a Water treatment Plant. Ideally I'd like for it to be a touch screen so that I can package it completely inside a control panel without having to worry about the attached keyboard and mouse.

Does anyone know if there are industrial touch screens out there that have linux drivers available? Otherwise we may have to go with either a non-touchscreen option, or install a Win XP option such as the Wyse thin client mentioned previously in this thread.

Thoughts?

Have you tried Advantech?

Just did an entire line using their 19" touchscreen touch monitors along with the Foxconn Nettop PC I mentioned earlier. Got the Penmount driver working under Ubuntu without a hiccup.

Unfortunately, I had to go to XP because I was having issues routing through the wireless connection to the hard-wired PLC connection and keeping it stable-- admittedly the problem was probably between the chair and the keyboard on that one!

Aside from my infrastructure issues, though, I was very pleased with this setup under Ubuntu-- and I was able to put it together for about $1280 each!

Monitor: $990
PC: $170
2Gb Memory: $30
32Gb SSD: $90

Where is anyone finding a version of JRE that will install on a thin client? The Oracle website just runs me around in circles, and only offers a version which is too big to be installed on my Wyse thin client.

I used the Wyse client several years ago without issue.

Wyse sent me to technote KB10687 (on the Wyse website). This got me closer, but JRE 6 is still too big. Anyone?

Ok, I hope this helps someone...

I'm using the Wyse R90L with XPe. I closely followed the directions in Wyse technote KB10687 along with JRE v6 on a USB stick, file name jre-6u27-windows-i586.exe. This worked.

Good luck!

Weird. Did the same thing with the second Wyse thin client and had different results.

1. FBWF Disable
2. Ramdisk from 30 MB to 64 MB
3. TEMP & TMP variables from Z:\ to D:\ (my USB stick)

When I run the Java install from the USB stick, I get an 'out of disk space' error. Any suggestions?

I am trying to follow along with out a manual...

FBWF Disable means what?

File Based Write Filter

It must be disabled to save changes to the client.

5 out of 6 thin clients set up using Wyse technote KB10687. Must be something odd with #6.

So this is the feature that preserves your bootimage, and makes it bullet proof?

Turn if off to make the changes in the bootimage and then turn it back on.

Any changes made without this won't be there after a reboot.

Did I get close?
