IllegalArgumentException: Null URI

[Tiger79]

Him
I am getting a meesage of an uncaught IllegalArgumentException: Null URI...
This is happening around the time I am using the Bluetooth API and the RMS API... I have looked on the net but no info is available regarding this specific error, so I was wondering if anyone had any experience with it and maybe knows which kind of method calls (in the above-mentioned API's) can throw this exception....

thx in advance

Check first the method calls you use to open the bluetooth connection. The Exceptioon you get is quite general ("Thrown to indicate that a method has been passed an illegal or inappropriate argument."), it looks like you have one of the parameters (the URI) you are passing to some method call as not defined...

But in general, first you need to debug your code more, and if that does not help, you have to provide more information about the problem.

true,
but as far as i know no parameter called URI is used in my own interface towards the before mentioned J2ME API's (RMS and BT) and also i havent found any documentation regarding anything of an URI in those API's....

debugging as known is hell on J2ME, especially with Bluetooth !
On the Emulator I dont get any error, but on the mobile phone itself (N95) I do and I actually get a Symbian-thrown Alert telling me there has been an uncaught exception... Then I look at another midlet which catches all the system.out messages and then i can see what kind of exception it is (IllegalArgumentException)...

so about the debugging part, I actually spend 2 full work-days trying to figure this out but with no result... The app runs fine on the S40 Nokia 6233 and the emulator...

Yes, I know that debugging is time-consuming and complicated on Java ME devices. However, if you could find a specific part of the code, which throws the exception, then we are much closer to some answers
