I've been using the "Java SWT version" of an app called PasswordSafe for many years on my Mac machines. It has been rock-solid. I've just bought a new iMac with the M1 processor because the "Fusion Drive" in my 2017 vintage iMac died. I installed Java, and the latest version of Java PasswordSafe on my new M1 iMac. Unfortunately, something is not working properly: The "top level" GUI looks normal, and it can open my PasswordSafe database file, but it presents a very garbled interface when I (for example) try to edit a password entry in the database.
I don't know much about Java - or SWT - never having written a single line of code in either. I've contacted the author of PasswordSafe, but he tells me that Java PasswordSafe is no longer being maintained.
In brief summary, my question is, "In trying to repair this broken-ness, Where should I start? I realize that's a very lame question, but let me try to explain what I'm trying to learn:
AIUI, Oracle no longer supports or provides a JRE or JDK that's compatible with the M1. I've read that a third party does provide these tools, but apparently Rosetta allows the Oracle tools to run on the M1. In fact, during installation of Oracle's JRE/JDK, I saw a brief popup notification re Rosetta. My conclusion from this is that the Java software components (JVM or whatever) are operating, although sluggishly, and perhaps with other flaws due to Rosetta imperfections?
The assumption that Java is more or less operational leads me to wonder about SWT. There is another recent question here on SO re issues with the SWT, but in my case, I get no displayed runtime errors - only a mangled interface. But then perhaps I'm not looking in the right place for those errors?
I've done a bit of research on the status of SWT on M1, but found no clues on their website. I haven't found any clear answers on whether or not SWT runs on M1 or not.
So that's what I've got - a very ill-defined situation with no obvious way ahead, and no experience in SWT or Java to guide me.

I was looking for a guideline on how to install or better said how to integrate an application into the Windows CE 7 run-time image.
Concretely I need to install Android SDK into the Win CE 7 Image.
If it is not possible then does anybody can say if is it possible to install it after
first boot. The same question can be applied on Java JRE for embedded devices.
In my situation I have ARM 7 based board with enough resources to run Win CE 7.
In fact I managed to install it. Now I need Java on it.
This question can be easily extended on other applications. It is always simple to install
something you made and know what registry entries, drivers and other applications you
need for running but in case of third party you have to ask or try it yourself.
Thanks in advance.
Your questions is vague or broad. I'm not sure which.
If you want to know how to integrate some application or DLL with the platform, then there's a general methodology of using REG/BIB and DAT files. This works for your own app of third party apps. It's how any file is put into the OS image, Java or otherwise. That's covered here and here
If you're asking about a JVM for CE, that's a completely different question, already answered here, here, here, and here.
Now when you talk about "SDK", which is "software developer's kit", it nearly sounds like you want to develop android apps on your CE device. That's somewhat asked (and not properly answered) here, but the answer is pretty much "there really isn't a tool for it and why would you do tyhis anyway?"
I am Java developer who is using Eclipse on a X86 computer to code. I am considering to buy for other reasons an Desktop Mac computer and I would like to use this computer to do my coding work. I know there is a Eclipse version for Macs, I am asking if there may be some problems/issues related to Macintosh computers. Thanks!
It really depends what you'll be doing.
In terms of the IDE, it will work just fine and you can copy your files/projects over and they will "just work".
However, there are some things you need to be weary of:
Key mappings might be different
You won't be able to do any JavaME programming as there is no Mac toolkit for that.
If you're doing Swing development, make sure you test your code on your target environment as things might look different.
Other than that, Macs work fantastic for Java coding.
No, Eclipse works just as well on a Mac as on a Windows or Linux computer. Key bindings are different though; if you're used to the shortcut keys of Eclipse on Windows, you'll need to get used to different shortcuts on the Mac.
Apple just announced that they are deprecating their Java platform. That may cause some problems in the future. Update: however, I have seen that Eclipse works with the soylatte OpenJDK port.

From my personal experience, Eclipse actually works better on OS X and Linux than it does on Windows. I'm a professional plugins developer and I do all my coding on Mac. I blog about Eclipse and Mac related topics, so I invite to read it.
Adding to the limitations mentioned in other answers, if you have specific plugins that you need, not all support Macs, although most. For example, The Eclipse TPTP (short for profiler) project doesn’t profile on Mac. There are alternatives in most cases, though (AFAIK, not free in the case of TPTP).
Personal experience for RCP-development: 2G of RAM are not enough (at least not for our project), so the current MacBook Airs are not suitable at all for development. But then, you're talking about desktop Macs anyway, so if you can get the >2G, it should be fine.
During the 64bit transition phase, there were some glitches with missing 64bit Cocoa, but that has been resolved. Some of the extensions may be platform specific: currently, TPTP (Test and Performance Tools Platform Project) still has some limitation.
eclipse for mac works exactly as you know it from your pc. the only thing that differs is the arrangement of some keys (the # is on L, the arrangement of the braces differs a bit)
Eclipse works fine, but with different keybindings.
I have found that sharing files with other computers - e.g. through a source repository - may give you character set conversion issues. If you stay with pure ASCII in your source you should not have any problems.
You can download Eclipse 3.6.1 from eclipse.org directly (where your platform is autodetected) or from http://download.eclipse.org/eclipse/downloads/drops/R-3.6.1-201009090800/index.php#EclipseSDK
I would suggest getting the Java EE version from the frontpage. It contains web stuff I use regularily.

We're looking for an alternative to Java web start that effectively does the same thing, just better implemented. We're having massive trouble with it. We have a few offices of XP desktops, all slightly different and so far only a handful have worked without serious tweaking. Problems are to do with not playing nicely with the proxy settings (using direct connection in Java control panel allows it to work), refusing to run when params like "-Xmx" are set but running fine when they aren't (until it runs out of memory) and other odd problems that we can't fix.
The way web start works is exactly what we want, i.e. connecting to a server that has the app, downloading anything that's changed, keeping a cache of jars, etc. Other teams here use 'clickonce' for their C# apps and it does effectively the same thing but seems to be less trouble.
I'm convinced we're not the only people to have run into this but searching around doesn't really show any alternatives. We've looked into writing a stub local application that is essentially just a URLClassLoader that loads up our app over the network on the fly but unfortunately that's too slow from other offices. Anyone have any ideas?
Thanks
Update
In case anyone is curious as to what eventually happened, we gave webstart another month or so but continued to run into problems so we implemented our own version. It's basically just a stub that has a URL class loader that you point at a webserver. It's < 200 lines of code and it has been working perfectly for months. It's not ideal but until someone improves webstart we'll stick with it.
Update 2018
So, several years later and I'm working on a new project with the same problem. Instead of writing our own webstart implementation this time we're using getdown. We've found it to be a vast improvement over web start and it's been working really well for us.
My company is also experiencing webstart pain especially with JRE 1.6 update 19 and 20. Our problems revolve around the Mixed Code security warning. (everything is properly signed and the problem is intermittent)
Anyhoo, I stumbled across getdown by threerings. I haven't tried it yet, but seems promising https://github.com/threerings/getdown/wiki
I use JWS extensively in my company. The ONLY real problem that I've seen with JWS occurs only when you try to run JWS from cache AND your client's machine has just upgraded to a newer version of Java. The application will fail to launch with a "Unable to launch", "cache file not found" error or something similar.
There are two ways that I use to fix this problem: I either clear the cache and have them reinstall the app, or I simply have them click on the URL again from my website (easiest for my users). In both cases, the problem fixes itself. This would explain why several developers here never see this problem, most likely because their users always click on a URL instead of the installed launcher.
As a workaround, and in some of my mission critical apps, I use either of the following inside a script:
java -jar netx.jar -jnlp http://url/to/my/launch.jnlp
or
javaws http://url/to/my/launch.jnlp
where netx is a third party library.
It is not the prettiest solution, but for me these work 100% of the time.
Now, if I could only figure out how to get the desktop shortcuts from not going to hell... but that's a discussion for another time.
I find all your probles quite strange. i've worked during a certain time in a company distributing its trading software using JWS, and it always worked really fine. Have you considering taking a look at the unofficial Java web start FAQ before dropping the whole technology ?
we also use JWS a lot and since around 1-6_19 it realy started to be a pain. Some apps started up 1-6_19 others didn't then we updated to 1-6_20 and it was sort of the other way around. Then update to 1-6_21/2/3/4 and problems only changing. We might give up. It looks like the development team since Oracle took over changed. Otherwise there is no other explanation to make JWS worse then better.
GetDown seems to be flaky as well. I just tried some of the game websites they advertise as examples in action. They all failed to load in my Firefox. Maybe my Java to Firefox integration is to blame? I've got JRE 7 32-bit installed after JDK 1.6 64-bit.
In general Web Start problems and poor user experience many times are related to the way Java was installed on the users machine. On Windows I noticed that if you install older version of Java after newer (expecting both will co-exist), I start getting problems running applets and WS applications.
Greetings,
I have read that QuickTime for Java is esentially broken on both Windows 7 and Snow Leopard. I can't tell how broken -- doesn't seem broken, but could just be my setup. I'm trying to determine whether this is a good technology stack, or if I should look elsewhere.
Objective: I want to build a specialized desktop video player and annotation program for both Mac and Windows (and Linux if possible). I think I want to use JavaFX (JavaFX as a Flash/Flex alternative that can use all Java libs and can build a decent UI.) I need to use something like QuickTime vs. Flash video as I need frame-accurate playback and wide codec support. I'd prefer to code in a relatively high-level language (not C++).
Thanks,
Cameron
Apple seems to have abandon QT for Java. Wikipedia's QuickTime for Java page seems to sum it up well. A select quote:
Currently most of QTJ is broken on
recent windows-running computers.
Windows machines that use the
no-execute (NX) page-protection
security feature of recent CPUs cannot
run even the demos without changing
the configuration. This can be easily
verified by a developer via a test-run
of one of the demos coming with QTJ.
An "execution protection violation" is
reported and the program is aborted by
Windows. This renders QTJ unsuitable
for end-user application development
due to the necessary complicated
configuration of the NX feature.
So, not good.
Following the 2003 release of QTJ 6.1,
Apple has made few updates to QTJ,
mostly fixing bugs. Notably, QuickTime
7 was the first version of QuickTime
not to be accompanied or followed by a
QTJ release that wrapped the new
native API's. QuickTime 7's new API's,
such as those for working with
metadata and with frame-reordering
codecs, are not available to QTJ
programmers. Apple has also not
offered new classes to provide the
capture preview functionality that was
present in versions of QTJ prior to
6.1. Indeed, QTJ is dependent on some native API's that Apple no longer
recommends, most notably QuickDraw.
And probably not going to look good. Ever.
Have you tried Xuggler? It should work for you.
Is anyone else having trouble running Swing applications from IntelliJ IDEA 8 Milestone 1? Even the simplest application of showing an empty JFrame seems to crash the JVM. I don't get a stack trace or anything, it looks like the JVM itself crashes and Windows shows me a pop-up that says the usual "This process is no longer responding" message.
Console applications work fine, and my Swing code works fine when launching from Netbeans or from the command line. I'm running Windows Vista x64 with the JDK 1.6 Update 10 beta, which may be a configuration the Jetbrains guys haven't run into yet.
Ask your question directly on the IDEA website. They always react fast and the problem you have is probably either fixed or documented.
I have actually experienced problems from using the JDK 6u10 beta myself and had to downgrade to JDK 6u7 for the time being. This solved some of my problems with among other things swing.
Also, i have been running IJ8M1 since the 'release' and I am very satisfied with it, especially if you regard the "beta" tag. It feels snappier and also supports multiple cores which makes my development machine rejoice. ;p
Anyway, i use WinXP32 and IJ8M1 with JDK 6u7 and that is afaik very stable indeed.
IDEA 8 Milestone 1 is a beta(ish) "based on a new platform". This may have changed the way that swing is handled. Also you are running a beta JDK.
You will probably get more help/submit a bug at the Jetbrain forums unless they are on SO also. Here is the bug tracker link
