Setup & Installation / Re: Desktop screen shots

Your picture: scrprt.png (176.13 kB, 1280x1024)
My picture: desktop.jpg (133.28 kB, 1024x768)
My picture is about 40kB less. The difference is in the format. Your's png and mine jpg.

You should sacrifice the 40kBs and use png as it is lossless and gives a better picture, especially with stuff like text. Exception is if you're starting with a JPEG picture.
In the case of the way the net is going its better to go for a JPEG picture, because you can protect it better then possible with a PNG version. With JPEG I have control over quality and smoothing.

BTW, mine's grey to save a few bytes.
No, it did not, sorry.

eCS 1.2 Dutch
Is the red X near the top left corner a result of upgrading eCS 1.2's eCenter by installing xCenter? I still have to test how seamless such an upgrade is; hence the question w.r.t. a missing eCenter button.[/quote]
Long time ago I thought that xCenter had more functionality, it didn't and its far less stable. You have to maintain it more and it does have problems with handles. At a certain point the ini seems to be too polluted and you don't get your desktop up and running. Instead you get a message. Abort and re install an old desktop. Running Checkini doesn't work sufficient at some point if the pollution is severe. Also its a nightmare with installation, never thought that this specific program is nested so wide and deep in the system. So this was my big mistake. For now its stable and running, but with testing Java stuff and other programs it will go wrong at some point. So stick to what's delivered with eCS or ArcaOs.

eCS 1.2 Dutch and a hybrid DOS for emulating Psion systems. eCS is my daily system. Everything you can find on my homepage about Java is installed. For the rest of it, the regular programs found on most systems.
I use a Wacom Bamboo Pen, no mouse. Screen size 1024x768. My monitor can show more, but then it is too small for me. Sometimes I don't show the bar above the picture, you then only see the picture. Very nice with W-users around ;-). I still have some Psions around and the computer is backup and more. I usually run the Psion emulator in DOSbox, in that case I can test with several emulations next to each other. I still use very old DOS programs because there is not a real replacement or the replacement is more then 10 times the size without serious more functions or capabilities in the program, as an example PC-Outline. Also use Win16 session with W3 programs for the Psions or for converting files to an other format.

I use cmd files with a certain standard setup. Because its almost standard only the line with the java program has to be changed. Once you have a cmd file you can drag it to any place you want in the menu structure of OS/2. If you want examples go to my site

First of all, never run DOS or WIN3.1 full screen, it is possible, but your mouse won't work or in case of WIN3.1 only half screen. So always run in a windowed session. When you do that you have full control with your mouse.

When you go to DOS then you go to DOS, so you have to deal with what you see right know. You have to make an autoexec.bat and this file is in the root of you boot drive with OS/2 or ARCAOS.
It could contain this, but back in the DOS days they have written many books about the subject;
PROMPT $e[1;1H$e[31;46m Datum ──$g $d $e[30;40m $e[31;46m$e[1;26H Directory ──$g $p $e[25;1HOpdracht? ──$g$e[36;40m$e[0m

Behind the prompt you see lots of ansi commands. The question is in Dutch and is just the Dutch version of "Command". The other two are "Date" and "Directory". You need some set commands for pointing to the right directory. I forgot what's all about, that's the curse of OS/2. Do it once and never go back and it will run and run and run... My boot drive is H:. In drive D: I have DOS programs and is formatted as FAT. You can make a complete key driven menu with ansi if you want. Its faster than your mouse, but you need to write some batch files.
I don't run WIN3.1 as a standalone window. I have pictogram's all over in the drop down menu's between the OS/2 programs. Its working seamless, so once installing and tuning and never see it again. It is no problem to run more WIN3.1 programs concurrent in this way.

There is one problem with DOS programs and sometimes WIN3.1 programs. That is if those programs want the whole machine. This is not allowed in OS/2 as OS/2 is the captain of your ship so to say. Those programs can be run with DOSBOX, but in DOSBOX you will also have incompatabilities and you need to make a config.sys and an autoexec.bat. Said that, once done, it runs and runs and runs. My Psion 3a emulator runs in DOSBOX with the same speed as an Psion 3MX. Nice to know is that you can copy and past in DOS programs with OS/2, even if those programs doesn't know what this is.

Hope it helps.

It is no problem to make very large mouse pointer with the pictogram editor program. However, once saved to a set it will load, but resized by the system to 32x32. I had made a mouse pointer with a gridsize 64x64, where it should be active is also accepted in the editor.

USB is a bit tricky. Depends on what motherboard you have. There are more ports on your motherboard and it greatly depends what number they have.

I did read a little bit on the Oracle site. The pricing is for older versions of Java which have to be maintained for users who need to stay on some level due to other programs or programs based on an older version of Java. So the pricing is for maintaining version of Java 6, 7 and 8. Java 8 will be end of life at January 2019, after that you can only get updates and security fixes if you pay a price. That's it. Java 11, current version, is free as far as I can read. So it has more to do with maintenance with a low volume of customers. And this is expensive to do, so the pricing.
If you don't want to pay (....) then they advice those users to go to OpenJDK, because that's free but doesn't have all the latest security fixes.

I'm more concerned about the fact that Java 11 is only 64bit as far as I did see at the moment. And we are still on half of that. I don't know if a 64bit source can be compiled for a 32bit OS.
So far my view, but I might be wrong.

There will be never an issue with Oracle simply because they don't have Java for OS/2. Said that, I don't know which law system they use, so there might be a trap door. But even with source they can't hold up because the source wouldn't compile into an OS/2 executable. So I don't think we will get problems. I do see that more and more software used by companies or governments are java based, this rules out to have several executable for every used platform which in turn is more easy to maintain company wise.

I have updated the pages "Test phase" and "Disapproved" The Dutch pages were far behind and are now on same level. You can find the page "Testfase" here and the page "Afgekeurd" here

Have fun!

I have added a game, or better said a game machine/server/host, today to my homepage. Its called Vassal and is a Java program. Once installed you can download over 2000(!) modules. Each module is a game. At the time of writing, if you want to play one module pro day, you will need about 5.6 years(!) to cover the amount available today. This is the hello screen from Vassal.

You can read more, with some links, on this page and this is the Dutch page

Have fun!

Java1.6 is 2.1.8a TTBOMK? You run this on OS/2-eCS or ArcaOS? SmartGit is programmed for the Sun version of Java, anything else will have problems due to incompatibilities. Tried SmartGit long time ago and it failed on versions of Java for OS/2-eCS.

About some other Java apps.

I noticed GreenFoot ( and Alice ( but I was no able to make them run. Not because of any error, I just didn't found the right way to call the .jar.  (both seems to be platform independent, but I don't know).

Hello Martin, Greenfoot, see last page of this topic. Alice can not run on OS/2-eCS/ArcaOS. There are some files specific for the used OS and there is no OS/2 version of Alice. There is also a lot of py, but that's solvable. The specific OS related files not.

Applications / Re: DOS and Win-OS/2 Windowed Sessions
« on: August 25, 2018, 11:30:51 pm »
Actually, neither Panorama nor SNAP supports DOS/Windows seamless sessions.
I run eCS with snap driver and I don't have any problems with seamless operation of DOS or Win16 windows. The only thing in DOS or Win16 FULL screen operations is that your mouse won't work as well due to the enhanced resolutions. So you have to run it in windowed sessions. Can even copy and paste in DOS sessions with programs which do not know what a mouse or copy and paste is.
