Web Browser control not shwoing Java applets on Vista\longhorn x64

Question

 

I created a simple .Net windows application (targetted to x86 platform since Java does not have x64 bit support) with Web Browser control in it. Whenever i try to browse an applet in web browser control (example: http://java.sun.com/applets/jdk/1.4/demo/applets/Animator/example1.html
), web browser control pops a Java window and get stuck there and do not show me the applet. I am using  JRE version 1.6.0_05. This is only happening on Longhorn and Vista x64 bit. Windows 2003 x64 works fine. On all other platforms, this .Net executable works fine.

 

I tried everything suggested in following blog but still same issue

Do we know any known issues with Vista/longhorn x64 web browser cotnrols and Java applets?

 

Thanks,

Salim

 

 

Answer 1

I am having the exact same problem as stated above and I have tried to do everything I possibly could to get it to work but have failed to find any working solutions.

I have other applications (not created by me, I only have the executable) that works just fine using either the ActiveX control or the .Net WebBrowser control and Java - so I am wondering if this is possibly a compiler / IDE Environment bug related to VS2008?

I have also tried to compile this under XP 32bit and then copying the executable over to my x64 Vista machine - but with the same results.

Answer 2

This is clearly a JVM problem.  You'll have to post to a Sun support forum.

Answer 3

Yes, this is indeed a JVM problem and i already filed a bug report with Sun and they reviewed and accepted it.

Here is their repsonse

Answer 4

I guess this problem might have been fixed already looking at the previous post dates. But I had the same problem now and when searching the net found this post.

My problem got fixed by compiling my code specifically for x86 (Instead of "Any CPU")

Answer 5

We had the same problem up until recently and this has been fixed in latest JVM. For those who don't have the option to build the app as a 32-bit by changing the platform target to x86 try downloading and installing the latest 64-bit JVM java version "1.7.0_05". It should fix this issue.
