Hello

I am developping an application for my mobile phone (6136) s40.
I use FileConnection API (JSR-75) to write some data in a file.
The problem is that my midlet prompt to the user (me) frequently if I agree to access to the fileConnection...

I read "MIDP 2.0: Signed MIDlet Developer's Guide v2.0", and I undestand that the solution is to sign my Midlet.

I will be the only user of this application on my phone and I develop for fun, not for making money...
So I don't wan't to pay for signing my application.
I see on Verisign that the price are very high. I am not ready to spend so much for that...

So do you know if there is a low cost solution ?
Is it possible to tell to my phone that my application must run as trusted without signing it ?

1-year valid certificate from Thawte cost me $199.
Maybe S40 3rd allows a user to add custom certificate into its trustore, like S60 do, or not?

"Maybe S40 3rd allows a user to add custom certificate into its trustore"

Not possible

'like S60 do, or not?"

Not possible on S60 devices either (except on S60 2nd Edition devices)

Hello

There is perharps a solution without signing my midlet :
I see that when I go to my mobile phone to
Menu/Applications/Collections/My application/Options/App. access/Data access
In this menu I can configure
1°/ Multimedia rec.
2°/ Read user data
3°/ Add and edit data

And for each menu item, I have the following sub items :
A°/ Ask every time
B°/ Ask first time only
C°/ Always allowed
D°/ Not allowed

The problem is this that some sub items are disabled :
A B C D
1 X
2 X X
3 X X
for example 3 B : I cannot for "Add and edit data" select "Ask first time only".

Is it possible to enable these sub-menu items on my device (6136 s40) without signing my midlet ? And so why are theses options are disabled ?

$199 is very very expensive !!! And it's only for a year.
But thanks for this answer.

I have another question :
When I go to my phone in :
Menu/Security/User certificates (and Authorithy certificates)
When you means "Maybe S40 3rd allows a user to add custom certificate into its trustore", you want to tell about this user certificates ?

Is it possible to add a user certificate ?
And what is it doing for ?

Thanks for advance....

No.

Those menu options are disabled because the MIDlet is unsigned. Installing a signed MIDlet will enable more of those menu options.

That fact that S40/S60 3rd have their trustores closed is very sad.

I cannot understand this policy.

This is as recommended in MIDP 2/JTWI/MSA. You should file a comment to the MIDP 3 JSR about this matter.
