i have an applet prided by jnlp this applet is thawte signed. so its a trusted app.
this morning a client call me beacause he can't launch my app.
indeed on his desktop the user have a strange warning screen :
after turning around for a moment i trow an eye on java security advanced setings.
we had lost an half working day to find a clue in our app or in the builsd process, but in fact the problem was a missconfiguration on the user desktop.
so because this king of advert is not showed on oracle docs and anywehe i search before, and because it could cause some trouble with users, time waste for dev team, and money lost at the end, i give you a solution for quick fix.
look the answer to know what to do.
in java config security advanced scroll until user evironment security and be shure :
user can allow special authorisations to signed content is check
display sandbox warning is check
not to ask for client certificate when none exists or that one is check
Warn mismatch site certificate and hostname is check
and signed app with all-permission launch again
