I suspect the goal is a way to bring Java desktop applications into the browser without rewriting the application from scratch. Personally, as a fan of Blazor, I thought this was going to be a Java-based analog of Blazor; or a modernized replacement for GWT. (One flavor of Blazor compiles C# to WAS…

>as a fan of Blazor I really dislike this stuff. It's easy-ish to write, but it's like the authors of it hate everything about the web. SPAs do a lot of annoying stuff, and blazor encourages all of it. I really hope things swing back away from this grotesque tight binding between the server and the client.

I think you’re a little misconceived, WebAssembly runs entirely in the client and have no bindings to the server, as far as the server is concerned such apps may as well be static HTML. This is Blazor WebAssembly. It will be just as trivial to run such on Mac, Linux or Windows server or any other plain web servers.

TeaVM seems to be the same except it compiles Java to JavaScript which means has fast startup times.

Web browsers and their fundamental development foundations are best described as a set of mostly well meaning compromises, and so even modern browsers have been updated to support all the other disagreeable things you have mentioned, even having the ability to navigate the browser history within an SPA

With this and Ruffle, we will soon return to the days of Internet Explorer 6 but with 4k monitors! All we need now is to run ActiveX. I think BottledWine can run Windows executables in the browser, how hard would it be to simulate the ActiveX bindings?

Does anyone know a simple and portable flash and java player? A firefox 3 in a folder, or something like that. Or maybe a small linux in a virtual machine.

If the goal is to play old Flash games Flashpoint is very good. https://bluemaxima.org/flashpoint/

anyone remember dhtml, which allowed adding powerpoint-like transitions to hyperlinks?

DHTML was basically just a buzzword for the first SPA interactions. The first, real uses cases for XMLHttpRequests was sending chunks of HTML over the wire and updating the DOM via JavaScript - so “Dynamic HTML”

I had a book on DHTML in the late 90s long before ajax was a thing. It simply meant scripting the DOM. The MS version did have some fancy transition filters too.

When everything else fails, you can just boot up a full Windows VM: https://copy.sh/v86/?profile=windows98

If you run Windows and are jonesing for some ActiveX action, and want to be really careful, you can run WSL, run LXDE on WSL, and run https://copy.sh/v86/?profile=windows98 on Firefox on LXDE[1].

That’s maybe enough layers of indirection to make ActiveX safe :-)

If only we could get a new version of Java for the browser. Something more of a scripting language that is not compiled but interpreted. Could probably knock out a proof of concept in a week, might call it Javascript or something...

Could probably knock out a proof of concept in a week, might call it Javascript or something... I get the joke. It is sad though how Java didn't end up being the ubiquitous runtime for browsers... It started off so promising... Compiling source to byte code is really fast in Java (…

It still boggles my mind that Sun Microsystems fully owned the tech for the only ubiquitous browser plugin for full fledged applications with > 95% deployment and somehow screwed it up and went out of business a few years later. Despite all their engineering prowess it seems like they just couldn't make Java work seamlessly and smoothly. I'd like to think it was just a hard engineering challenge, but as someone who went all in on Java WebStart for deployment at one point and then watched them take it from a highly attractive platform to actively ruining it within a few years, I have to attribute it more to incompetence.
