Added the nios-wiki page it describes the basic steps needed to get the java programs running on nios2 using uclinux hopefully they are clear enough

But kvm is really quiet new v1.1 and also it makes no commercial sense in a booming market of embedded systems to open kvm source/ although development can progress faster with it being open source... But thats just my 2cents http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/tongue.gif    regards,

Hello, 

may I ask you, where can I download java vritual machine ?  When I find this on nioswiki http://www.nioswiki.com/operatingsystems/uclinux/running_java_on_uclinux-niosii_board   and try link: http://www.sun.com/software/communitysource/j2me/cldc/download.xml (http://www.sun.com/software/communitysource/j2me/cldc/download.xml)   it switch me to http://www.sun.com/software/opensource/index.jsp and I am not able to download java virtual machine.   Could you advice me ?    Thank you very much.   Jan Naceradsky, Czech Republic

I found this:  

 http://hg.openjdk.java.net/  Is this not the appropriate page ?   -Michael

I am not sure, I can not find the download of java virtual machine ... 

but in distribution of uClinux I found the Javm directory, isn¨t it, what i am finding ?  :-)   Jan Naceradsky

Hi all,  

 I have the same problem.  It seems to be deprecated, and replaced by CLDC HotSpot Implementation. But i don't understand what to do with it, and i don't know where to download it too !!!  By the way, i would like to thank all of team who write the niosWiki. It's a pity that it's not maintained.  Anyone knows how to run a java program on a niosII µClinux, with or without KVM ?

[Altera_Forum]

Hmm, i try to compile the kernel with JavaVM, but it finishedd with error.  

Could you tell me, where is error or is anybody who has the kernel uClinux with Java VM ?   Thank you very much.   Jan Naceradsky, Czech Republic

If you don't give us errors, we can't help you.  

But, i think JVM is not runnable on a µClinux because it's too heavy for this embedded OS. It's for this reason that we must install KVM.  This is what i've understood, but i'm not sure.
