Hello aamitgupta,

.. read some value from file and write some value in to file but Security Exception comes..

For further evaluation, would you please send the piece of code in which you're trying to read and write. (Signing may not be needed at all.)

(I'm guessing here, but if you're using PIM API (JSR-75) and you're trying to write to a PIM database which is opened as READ, this SecurityExeception will be thrown. Try using READ_WRITE instead.)

.. and check if you have declared your Midlet's required permission .
For example on sun wireless toolkit select project ->settings -> permissions. You have to add your midlet's requrementto write/read files.

Thanks for reply, i did this process and but Security Exception is comes, and my another requirement is that i want mobile IMEI number, Sim identification number, network name, which is by S60 3rd Edition Feature Pack 2 , by System.getProperty(),

"com.nokia.mid.imei", "com.nokia.mid.imsi", "com.nokia.mid.networkid", "com.nokia.mid.networksignal",
"com.nokia.mid.networkavailability", "com.nokia.mid.batterylevel", "com.nokia.mid.countrycode","com.nokia.mid.dateformat", "com.nokia.mid.timeformat"

But these values are Null, because for this midlet is signed by certificate so i want certificate for nokia but i don't know how?

Please help me How can i sign my midlet?


Thanks and Regards

most of the properties you want to access (like networkid, imsi, signal, etc.) are not available for MIDlets. It does not help even if you sign your MIDlet
IMEI should be accessible on (newer) S60 devices though.

But on documentation mentioned that if midlet signed that will get the value on newer devices.

Hmmm... sorry... My memory failed me a little (and things have changed a little since I last checked...).
IMSI requires manufacturer or operator signing. Others in the list should be available on S60 3rd Edition FP2 as you mentioned. However the SDK is still beta, so it might not work properly.

Nokia signing requires that the MIDlet is developed by Nokia or Nokia branded. You will not get manufacturer signing for other MIDlets.

Yes, unless your application is Nokia branded (and passes the required tests, including Java Verified) your MIDlet will not get signed to manufacturer domain on Nokia devices.
BTW this is quite similar policy to what Sony Ericsson has
"Manufacturer signing requires MIDlet to be Sony Ericsson owned or licensed"
