Testing eCS Java 6 (1.6 beta) with a swing intensive application like iTrain

Severity: low Keywords: Swing, AWT, serial port support


I'm running my modeltrains with the in Java written program iTrain ( So I was very curious to see if it would run on eCS. Just tested the 1.6 JRE beta with the latest Beta version 2.0.0-b44 of iTrain (build 2011/01/02). Here are some results:

  1. Installation of iTrain runs fine, except the progress bars, they were empty and therefore nothing visible happened.
  2. iTrain is coming with two special Java DLL's for serial port support (JSPOS2J.DLL and SCCOMIO.DLL) for OS/2. Still there is no serial port connection possible. Both DLL's were put in the /JRE/bin directory and Java 1.6 crashed as soon as in the iTrain application the menu to check the serial interface was opened. Below you will find the output of the commandline during the crash:

OpenJDK Client VM (build 16.0-b13, mixed mode)

  1. iTrain is a heavy swing application. On the eCS 2.0 platform with Java 1.6 beta no "drag and drop" was possible within the iTrain application (e.g. it should be possible to drag a locomotive from the loc list to the throttle window, see also attached screenshot). Furthermore some context menu's disappear as soon as they were tried to open.

These are my first impressions with Java 1.6 beta for OS/2 & eCS tested on a T42 IBM Thinkpad

Seems that the serial port driver stems from: and is embedded in the itrain application.

The serial port communication is not required in order to use this app, the most important problem is the lack of drag & drop.

I tried to install this application and see several problems with the installer:

  1. It doesn't show the license files to me (just empty text boxes).
  2. It cannot create an installation directory.

Note that the problem 2 I also saw with the jEdit installer. I will look into them first.

And there is indeed some problem with DND. I can see it in the Notepad.jar demo application (when dragging the text). Created #45 for the DnD issue and #46 for the directory problem.

BTW, I fixed #46 and installed iTrain using its installer and in my case progress bars work just well. I actually wonder how you could install iTrain with its installer at all with Beta as it should have failed when creating the installation directory.

Regarding the DLLs. Do you know what Java version these DLLs were originally written for? There may be a difference between the OS/2 JNI and WIN32OS2 (Odinized) JNI that makes them incompatible... I will check that later.

The problem with DLLs seems to be similar to the one we see in #49. We can't do much here w/o getting the source codes of these DLLs. And anyway this is beyond the original topic of this report (which is resolved now as iTrain works quite well besides the serial communication DLL).

If you find more details about the DLL (sources etc.) feel free to open a new ticket and we will look at it.
