Support forum: JAmiga

Welcome to the support forum for JAmiga - Java for AmigaOS!

This is the place to ask question on what JAmiga is, how it works, why it doesn't work, and also more general Java developer questions.

Bug reporting
If you have bug reports, with crashlogs, please use the os4depot crashlog area, and please state which JAR files you ran, and where it can be downloaded.

By double-clicking the JAmiga:JAmiga icon, you'll get info on which library and binary versions are in use.

Always make sure you're properly AmiUpdated, and have the latest versions installed. If you've experienced crashes, and the update, please reboot since old libraries might still be loaded.

JAmiga is available on os4depot/development/language/jamiga.lha

Great! Now i hope Hans, Broadblues, ChrisH and zzd10 join and help you with Jamiga.

Thanks!

sorry for the stupid question but I am a newbie java user.. is there any program/script that I can try to see if it works and how it works? and speaking about java, at this stage, can it be used to start learning java program language?

:)

just created this crashlog :http://crashlog.os4depot.net/cl397

hope you can help me with this...

Amigalement,

Hi, thanks for testing!

The error is due to the AWT packages (I.e. Graphics) not being implemented yet... Don't know if I'll add them this incarnation of Jamiga, or focus on getting Jamiga upto the official Oracle OpenJDK level.

as there is an awfull lot of java apps that needs gui to just work... I'll should go for AWT first

Thanks ^^)

Hello Jaokim ^^)

any news about an update for us ?

Thanks,
JF

Sorry to say, but no, no news regarding any updates. :(
I've been lacking motivation, and also time lately - a particularly bad combo.

As always I'm in a constant battle with myself whether I should try to get something GUI-like running with the current JAmiga, or try to port something newer... i.e. OpenJDK.

Java is really important for an updated operating system.. maybe a bounty could help you? Your work is really huge and I think a bounty could rise your motivation up! :)

@jaokim

Any way to use Intuition/MUI objects behind any internal java std lib abstractions?

What is needed for the updated java engine?

Would a "blank canvas" for output along with a basic "I got a click/key press" input handler possibly help?

@jaokim

I'd go first by figuring out what is really "needed" on Amiga straight away?

Do we need JAVA GUI?
or maybe forst off some simple non-gui java applets that run in the background?

Actually can someone point me towards a java program Amiga would benefit from (without having to port half of another OS)?

Thanks and thank you for the ongoing development jaokim

As it is, Jamiga can be used for some productive stuff. For instance I've got a Java compiler running using Jamiga (which of course is somewhatof a circular usage).

There's also the Twitter client, and a half done Git client (I mention them on the blog).I started working on a Dropbox client, which currently can communicate with Dropbox, but it's not at all integrated with AmigaOS.
These examples are basically simple Java programs I've created that uses available Java API:s. So I think there's always some amount of Java coding needed, if we want to utilise some of Java's strength without all of Java implemented.

I'd personally put basic graphics and GUI capability at the top of the list. It really is an elementary part of programming a desktop app.

That said, is jaokim truly intends to switch to porting OpenJDK in the future, then he should probably do that first. I expect that OpenJDK's AWT/graphics implementation would have a different native API compared to whatever JAmiga is using right now. If I'm wrong about that, then I think that GUI capability really should be at the top of the list.

If there's a bounty (which accepts PayPal) I would chip in for sure.

Given that I began with AWT/Swing stuff a while ago, I've now continued that track of development.
I wrote a bit about on the blog: http://jamiga2.blogspot.se/2016/03/swing-it-magistern.html

I also started a Trello to kepp track of what I'm doing. Mostly for my own use, but I think anyone who has a Trello accoutn can atleast comment. If you want to add stuff for me to do: just tell me, and I'll add it.

@jaokim

Nice to see some life again

Thank you very much for the ongoing development

@Marko

There is also a donate button on his blog if you want to show some support.

@Caras

Thanks for the tip!

PS: I just got to top up my paypal
