Sun Microsystem Open Sourced the Java Programing Model not to long ago.
Anybody looking into how the OpenJDK source code can be used for AmigaOS porting?

JAmiga is a 'from scratch' implementation of a Java Virtual Machine. It has been developed only from the JVM-Documentation provided by Sun Microsystems. It is not a Port of an existing JVM. Why have we decided to do a clean implementation ? JAmiga is a research project for us. We want to learn how Java works. Thus we decided to write a VM. The decision to write it for Amiga OS was made because of the lack of decent VMs for this platform.

I don't think any of those Java projects for Amiga are still active. Would be a shame if we lost the work done so far, do you think we could get the source code for the Java on Amiga projects open-sourced?

@HenryCase

I'm calling for a full review of the situation.

With the OpenJDK source code being available now, it might be a best practice thing to return to the Inception / Elaboration phases of the Java for Amiga life cycle.

Dunno if the poll was multi-select or not, but: "yes, I would use it" and "yes, I would use it for development.' - both writing apps and for the Eclipse IDE.

kaffe was ported a while back. I may have a poor recollection, but I believe 'it worked' except for the UI.

JAmiga was looking promising for a while, but I believe Peter (the main dev) sort of dropped off the face of the earth for a bit; I don't recall why, so it's effectively stalled right now.

You can certainly 'call' for anything you'd like, but unless you're actually doing the work..someone may not answer.

Java on Amiga PPC revisited...

Well today I got FlashBack - rewritten engine - to work on my SAM440EP
http://os4depot.net/index.php?function=showfile&file=game/adventure/reminiscence.lha

So it got me thinking the Amiga Community has a lot of software now, just imagine how much more software Amiga OS4.x could have, out of the box. (If it could run Java Apps)

Well???

Need a JDK to bootstrap openjdk build

Could use IcedTea, but AFAICT that requires porting other stuff first

Then ofcourse, once you get past that bootstrap hurdle things might be easy ...

JAmiga 0.0.6 - Java for OS4.1 is finally here.

Most of the CLASSES DEMO's work.
So it truly is Java on the Amiga.

eg: cd SDK:Java/CLASSES/
to execute: SDK:JAmiga/java TestScreen
and that runs the multi-coloured-lines demo in AWT.

I use Eclipse all the time as my IDE of choice. Java is what it is written in so I checked "Development".

@Samurai_Crow

Eclipse has been compiled natively for Linux/x86_64 using GCJ. I would attempt to get GCJ and then Eclipse working on AmigaOS before moving forward with an OpenJDK port.

Personally I dislike Java, but so many major packages depend on it for full functionality (OpenOffice comes immediately to mind) that it is something we desperately need. In addition there are things that use Java to create a platform independent GUI. Basically anything that makes porting apps from other platforms is a good thing for the Amiga.

Joakim is working on jamiga and updated it recently. I´m trying to convince another friend to help him and he borrowed my SAM so hopefully we will have two ppl working on it. He want more ppl to the project so if you have the time contact him! Samurai_Crow ?

I loaned my MicroA1-c out to the Aladdin 4D team. I don't have another AmigaOS 4 machine to develop anything with. My next Amiga-related purchase will probably run AmigaOS 3 natively rather than AmigaOS 4 anyway (referring to the NatAmi).
