SL-C750 and some software issues

[JustAnother]

Hello again! After my hardware shenanigans I'm stuck with some software troubles. Main thing – PalmOS emulator qpose. I'm installed it (both bin and data packages), obtained a ROM from site PalmDB, but upon starting emulator says "Please wait..." and after a couple of seconds closes without any error. Also it's starting with incorrect screen position (portrait instead of landscape), and libSDL installed (working, tested with emulator zgnuboy).

Second issue – Java, J2ME MIDP. Why – wanna run Opera Mini, just as proof that my little outdated device can browse modern internet. I found a pretty detailed instruction (here, section "MIDP"), made as it says, upon executing run command – in my case it looks like this:

Code: [Select]

evm -classpath ./me4se.jar:./midpx.jar:./opera-mini-8.0.jar org.me4se.MIDletRunner Browser

I've got an exception which looks like this:

Code: [Select]

Exception in thread "main", java.lang.NoSuchMethodError: java/lang/System.setProperty(Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
        at javax.microedition.midlet.ApplicationManager.setSystemProperty (bytecode 21)
        at javax.microedition.midlet.ApplicationManager.<init> (bytecode 186)
        at org.me4se.MIDletRunner.main (bytecode 147)

My code-experienced friend said that this is some locale issue, so someone can help me with that?

For the qpose issue, there's a how-to here which might be helpful: http://zaurus.kruss.com/howto-qpose.php

For the Java error: in your Java installation, the installed System class doesn't have a setProperty() method, or it doesn't expect two Strings as parameters. See if you have more than one "System.class" file, if so, check which of them is being used at run time by adding

Code: [Select]

-verbose:classin your command line.

Hello again and thanks for reply!

For the qpose issue, there's a how-to here which might be helpful: http://zaurus.kruss.com/howto-qpose.php

Unfortunately, how-to has no help 'cause in my case the emulator's GUI itself not starting -- according to screenshots I found there, it could be opened without PalmOS ROM. I'm uninstalled libSDL and tried to start qpose without it but to no avail. Maybe, I should try to start it via terminal but I doesn't know, how to do this: when I'm entered command qpose, system says that my display is 480x640 and this is all.

Added this argument and got something like this:

I'm obviously not the code guy, so what this log means?
