is empty
I downloaded and installed the archive in an other drawer & got the same results

this wbelow is the jamiga: content before trying to complete manually claaspath.lha can be dearchived in jamiga: drawer
for classes.lha i get an error

Well that's just plain wrong.

Can you remember if anything went wrong with the install? The installation should automatically run UnArc (SYS:Utilities/unarc) twice to perform the unpacking of all the classes (a lot of .class files). Have you made any changes that might affect UnArc?
When did your first install JAmiga? Can you remeber if it was from the full 1.1 or 1.2 archive, or perhaps even before that?

Either way, I think your best choice is to install JAmiga again, using the os4depot archive, and then AmiUpdate it.
No one else has reported similar issues, so it might be better to start fresh.

@jaokim
did that, see the completed install report above and ovbserved errors.
I did not get any hint the first time that somethinfg was not set up correctly.
obviously the classpath & classes archives were not dearchived.

it seems to me the first time and the second time the archives used were identical they had the same size.
the 2nd time i downloaded in ram though (just to verify if the sizes were diffferrent)

I just now did launch amiupdate, but it does not detect a jamiga update.

Could it be that it thinks it updated Jmiga allready?

@Joakim
I installed from lOS4Depot today

i intalled it in 3 different folders and got non systematic results, but always there was something missing.
From what i saw in the 3 installs i copypasted to have one probably(?) complete

I had the following resultswith the example

@JosDuchIt

Hmpf. It seems my installation script doesn't work very well for partitions with space in the name.

If you don't want to wait for me to fix the installation script, I *think* you could extract the two archives manually:
Extract classes.lha to "JAmiga:jvm/share/jamvm/classes"
Extract classpath.lha directly to "JAmiga:"

Or you can wait for me to fix the install script -- I'll put up the script as a single download, as well as replacing the os4depot archive.

The reason you got an error trying to extract classes.lha to JAmiga: directly, is that it has a drawer named "jamvm", which clashes with the binary file "jamvm".

Thank you for reporting your issue, being patient and trying different things! I guess other's must have had your problems as well!

I've now fixed the install script: you can download the script from here, and replace the old install-file from the os4depot archive with this new one (v 1.3). You can simply unpack it to the same directory.
I'll upload a new archive to os4depot soon.

Once again, thank you for testing, and sorry for the inconvenience!

@jaokim It seems the problem is still there;
- installled jamiga again using the new script (over the exisitng install) all seemed to go as wanted
- had Amiupdate replace the libs
- tested the compilation of Helloworld.java and got essentially the same result as in my previous post
- launched jamiga from Filer & got

@JosDuchIt
Oh no...
But, you're at lot closer now, the text "JAmiga has been successfully installed!" Is the JVM actually running a Java application. So that's one step closer.

Could you paste the output of the compile after this new install?

That error could be due to a missing jar-file in JAmiga:lib. It should've been installed with the developer's kit, but perhaps it's disappeared between your installs?

Anyhow, do a:

If everything is ok, you should hava a JAR-file, ecj-4.3.jar there.

If you don't, then that's what's wrong.

Then, in order to download the dev-kit again, you need to do:


If you run AmiUpdate now, you should have the JAmiga developers kit in the list again. And hopefully when you install it again, everything should work.

(If the AmiUpdate for some reason fails, it's most likely due to some file being locked by the JamVM process (yet another bug!). Please copy the "unpacked" dir in ram: to disk, reboot, and copy the "unpacked/JAmiga"-directory content to JAmiga:. Then, perhaps, if all the stars are aligned, it'll work.)

That's what I can come up with at the moment. Once again, thanks for your patience!

@ Joakim
There is no Dir jamiga:lib

- i deleted javac in " Amiga OS 4:system/jamiga" drawer
- dearchived the sdk in ram:jav/
- dearchived the new install script in the same drawer
- run the install script selecting "Amlga OS 4:System" as drawer where the jamiga drawer "would be created " (ther is one allready)
- chose to have a file log
- the whole procedure seemed to run normally (no hint that something was wrong)

but
- no jamiga/lib dir was created
- no replacemtn of javac

- I didn find the logfile

i don't find the ecj-4.3.jar nowhere in the archive not in the ram:java drawer, not in classes.lha and classpath.lha (manually unarched )

please note also i never run the def icon tutorial and i have drawers
jamige- and jamiga__ next to the jamiga drawer

I did find a jlib dir in a previous install and it contains ecj-4.3.jar

Now running Amiupdate
Results :
javac appears in the jamiga: drawer
jamiga:lib/ecj-4.3.jar present

??? did i missed that before Amiupdate? Or is this AmiUpdate's work???
If you want me more testing to do on this tell me


running jamiga:

Hallo Joseph

Thank you very much Joakim

@JosDuchIt

Great that you got it working! I think it all comes from my installer not coping with spaces. After your first install I can only assume that some AmiUpdated stuff wasn't copied correctly.

Once again, thank you for testing!
