Certificate expire, effects to installed MIDlet

[MrBoern]

I have a runing MIDlet on many customer mobiles out there.
It is signed with the "Thawte Code Signing CA".
My question is, how does the MIDlet act when the certificate expire.

you can test the situation setting the clock date to next year.
There should be no problem in using the application already installed.

I already test it by change the date and it's no problem.
I ask my question because i don't know if this test is adequate and if somebody have experience with this situation.
I have to know how the MIDlet act before the certificate expire.

Hi,
Supposing you bought a one-year certificate, if you sign now a midlet it can be installed also next year. But if you sign a midlet next year with a certificate bought this year the installation will fail.

Thanks for the answer matrix241,
But if I can install my MIDlet after it expire was not realy my question.

I want to know how an already installed MIDlet which was sign with an valide certificate act, when the certificate which was used for signing the MIDlet expire.

Here for clearness step-by-step what I want to know:
1. I compile my MIDlet and sign it with an valide certificate from Thawte
2. I install the MIDlet on many mobiles
3. The MIDlet run on these mobiles for a long time
4. Now the certificate which was used for signing the MIDlet expire (expire date: 13.02.07)
5. What happen when I start the MIDlet on the mobile after the certificate expire (start date: 14.02.07)?


Or is the signing only take effect at installation?

Of course I have already answered : the midlet will run correctly. You can search on the forum and you will find everywhere this.
