Jerome, Thanks for you help already. I am looking into already signed jars issue: http://jira.codehaus.org/browse/MPJNLP-28
(The webstart website wrongly refs http://jira.codehaus.org/browse/MOJO-263 instead) But it seems that the problem lies with the maven jar plugin,not jnlp itself. Could it be there is any progress in that in the newer jar snapshots?
