Hello,

I want to do a cometd demo in the Glassfish Day in Beijing, but failed when trying the last builds (V2, V2U1,nightly build...).
The error message is:

java.lang.NullPointerException
    at com.sun.grizzly.cometd.bayeux.Handshake.toJSON(Handshake.java:198)
    at com.sun.grizzly.cometd.BayeuxCometHandler.onHandshake(BayeuxCometHandler.java:100)

.....

It seems that Glassfish hasnot implement the Cometd protocol properly in these versions.
Can someone tell me which version can work well with cometd client (Dojo toolkit)?

Thanks and Best Regards
