Midlet permissions issue

[barbeNoire]

I need to access the Nokia N90's memory card file system.

After trying to make a simple :

FileConnection fconn = (FileConnection) Connector.open("file:///E:/Images/PlanParisPOI.JPG");


, I had part of this exception message : Permission = javax.micro (then the phone screen's width does not allow to

read the end
of the content).

Then I googled and read about midlet permissions.

So I added permissions for javax.microedition.io.Connector,javax.microedition.io.file.FileConnection into my

midlet's jad file.

Unfortunately, my midlet now fails to install on the mobile phone (authorization failed).

Here is my jad file content:

MIDlet-Version: 1.0.0
MIDlet-Vendor: Midlet Suite Vendor
MIDlet-Jar-URL: MyMidlet.jar
MicroEdition-Configuration: CLDC-1.0
MicroEdition-Profile: MIDP-2.0
MIDlet-1: ClientLourdSIG,,ClientLourdSIG
MIDlet-Permissions: javax.microedition.io.Connector,javax.microedition.io.file.FileConnection
MIDlet-Name: MyMidlet Midlet Suite


I am using Nokia S60 sdk + eclipseME.

Any ideas?

cheers

If I sign the midlet (I used the JDK keytool) then I can install the midlet on the mobile phone.

But the same exception keeps being raised when executing the midlet.

Any idea?

Please help me.


Thanks

Two permissions are defined for the Fileconnection API:
javax.microedition.io.Connector.file.read
javax.microedition.io.Connector.file.write

The read permission is used when a file is open in read mode or if an InputStream is opened from a FileConnection object.
The write permission is used to open files in write mode or if an OutputStream is opened from a FileConnection. It is also used when invoking other write operations like delete or rename.

If you are not granted the permission to access the restricted API, a SecurityException is thrown and it is important to manage these situations in your MIDlet.

To avoid the security/permission questions, you have to sign your midlet.

Hi,

But I have already signed my midlet and it didn't help. I also added the required permissions including javax.microedition.io.Connector.file.read and javax.microedition.io.Connector.file.write. What else should I do?

Besides, I have also tried my program on an older Nokia N90 and it worked!
So what could be the difference with the newer Nokia N90 that I got?

Thanks for helping

Is your N90 an operator branded one? I have read that operators can set restrictions for accessing certain API's.

Well, both phones belong to the same operator....

[balagopalks]

Please check whether the Phone software versions are also the same and also check whether an operator specific firmware is instaleld on your N90.

How can I check the firmware version of the Nokia N90 mobile phone please?

Thanks

I think what you need to do is this: after you install the signed application go to Tools>you app>options>suite-settings>change the last two settings to "always allowed".
I hope this will help

barbeNoire,
How to find our the firmware version of Nokia phone?
press *#0000# while in the idle screen (the one you make the phone calls from)

Is your operator Orange Israel?

Thank you so MUUUUUCHHHHHH!

I even don't need to fix any permissions!!!!!

I love you!

I'm signing my midlet with a certificate that comes in netbeans, I'm using a N81 phone, but it gives me an error when installing the midlet. The phone doesn't like that certificate, what can I do?

camilo2255, please do not hijack threads of others. Your question might be related, however it is a separate issue. Furthermore, the provided information is a bit spare to give an correct/good answer.

First of all, I recommend to go through this. I know this is a lot to read, however, you should really go through that. Especially the reference at the bottom should answer all other questions. I am not sure whether you understood that the certificate you are using needs its certificate authority on your phone, too. Consequently, you should go for a paid certificate like VeriSign or thawte. If you use one of those already and you have installation problems, please go through this post which contains a link to common pitfalls and how they are avoided.
