This looks fantastic. Can't wait for the release, later this year I hear? Three questions: 1. 64-bit support. Will JWebPane work on a 64-bit Windows JVM? Presumably with a different WebKit DLL. What about Flash in JWebPane on 64-bit? 2. Older JVMs. Presumably this is planned for JDK7+. Can we use it as a library/DLL suite in Java 6? Our app lags behind the leading JVM release for stability reasons, but we need JWebPane desperately. 3. Performance. I saw your slides - looks great. How about multiple JWebPanes shown simultaneously - say 4 - viewing arbitrary web pages. Does this hog much processor time and memory on a current PC? These questions are important to me, since I am long overdue developing an embedded web feature for our desktop app, and am under pressure to consider alternatives. I'm not expecting promises, but some indication of what you anticipate would be a great help.

Finally a web browser for Java platform...I'm waiting for something like this for years...When it's gonna be available? :)

Will there an api to traverse (and modify) the DOM of loaded pages?

+1, need it, want it :)

After looking at the slide, it seems that JWebpane is a major project with effort similar to JavaFX since it needs to run in all major OS platforms using Swing and native code. Though I am baffled why Sun did not put in more resources for strategic project like JWebPane to ensure that it completes in certain timeframe. It appears that strategic projects even like JavaFX, JWebpane etc seems understaff as indicate by lack of engagement, specificaton, progress compare to competitors like Silverlight, Flex ? Anyway if assuming that Oracle makes good its promise to invest in more resources in Java Technology and use its proven market-oriented approach, I'm sure Java has a bright future. I feel that Java is losing its edge in big way because its technology and plaform look very poorly market compare to products from Microsoft and Adobe. The engineers seems to be running the show and the marketing is secondary. The above is just my personal opinion.

OOOHhhhhhhhhhh really really awesome neewwwss !!!! cooooool !!

Fantastic, java and flash support! That's really great. I'm chomping at the bit to get my hands on it. Thank you very cool.

Wow, can't wait to use JWebPane... At present I am using JDIC to render html pages but JDIC has many limitations - does not work on Linux, and with FireFox 3.0 on Windows and with 64-bit Windows Vista. When will JWebPane be available?

no beta ? no RC ? why not using those steps (beta, RC) just like some other SUN softwares ? '"release early and often'" policy could bring here great interesting feedback and involve more possible customers. My 2 cents.

> 1. 64-bit support. Will JWebPane work on a 64-bit Windows JVM?

Yes, it should work on all platforms running jdk6. The only difference might be in number of plugins supported.

> What about Flash in JWebPane on 64-bit?

Our current flash support implemented through ActiveX container, so we will have have it on 64bit windows when it's available.

> 2. Older JVMs. Presumably this is planned for JDK7+. Can we use it as a library/DLL suite in Java 6?

Yes, JWebPane can be used starting java 6.

We haven't spent much time on footprint. We've been mostly tuning performance. So, the curent numbers (according to windows task manager) are:

1 google.com page - 58.5mb
2 google.com pages - 62.8mb
3 google.com pages - 63.9mb
4 google.com pages - 65mb

CPU load (P4-3000) with 4 bubblemark DHTML tests (http://bubblemark.com/dhtml.htm) running on separate pages is about 15%

I suppose we will know the release date within couple of month.

> Will there an api to traverse (and modify) the DOM of loaded pages?

Yes, we're going to introduce read/write access to the DOM of the pages

It looks fantastic but i have a question. What about flash on Mac and Linux?

Alexey, thanks for the reply. Green light answers for all my questions. Looking forward to the first release later this year (Q4 I hear).

> It looks fantastic but i have a question. What about flash on Mac and Linux?

Currently we don't have flash support on these platforms. But we plan to have it in the future. Not sure though wether it'll be lightweight.
