Hi

No problem "installing" as it seems to be a simple unzip to wherever.

I cannot get the app to run though...

I've tried both java.exe and javaw.exe and this is the error:-

[J:\Java\ArtOfIllusion261]J:\JAVA\JAVA142\JRE\BIN\JAVA.EXE -Xmx512m -jar J:\Java
\ArtOfIllusion261\ArtOfIllusion.jar

What am I doing wrong?

Hi guys,

did you make sure that the newer AOI is *still* intended for the Java142 we're using on eCS / OS2 ?
To me the symptom "smells" like it requires a newer JRE... I had that with other software in the past and it always truned out that it required a newer Java than we have (...I'm no java expert though).

Cheers,
Thomas

Hi again,

OK I have checked the AOI page and they simply say "Java 1.4"... well... however in the exception, there is
Quote(Unsupported major.minor version 49.0)

Now, what the heck is going on there? ;) I think I'll have to try this at home to see what the problem actually is - or in other words "check if that is the cause".

Cheers
Thomas

Hi Guys

I emailed Peter, the author, and had a response to the effect that 261 requires java1.5 or later - which is what I thought the java error messages indicated.

I have pointed out (politely) that the website needs updating...

Regards

Pete

Don't forget you can run this program in this way: http://home.arcor.de/michael.holzapfel/eCS/java/Using%20Java%20on%20eCS.html

I've tried. It works. Only issue is I get an unkillable aros2.exe when shutting down. It's just disturbing and you have to reboot if you want to start it again after closing.

UPDATE: Instead of using innowin and aros2.exe- you can use Odin and pe.exe. It works as well and I don't get any unkillable instances.

Cool. Thanks.
...is that approach (how-to) documented/available somewhere??

TIA

I don't know but I'll remember there was a thread about it somewhere in this forum.
