Hi,
I have just tried the GlassFish async sample. It is working fine for me.
You may like to restart your browser. Also, you may like to have two
different browsers to run the chat.
As mentioned by Jan, there is an bug in the sample.
That bug should not affect the functionality described above.
I have just fixed the sample in glassfish-sample svn repository.
Regards,
Shing Wai Chan
