If N70 supports filesystem access, you might consider logging and writing to the filesystem...

thanks Jim... that is exactly what I thought... Calculator thread should start after the reader threads have started... that gives me better confidence about my understanding ...

I am sure there must be some simple answer.. or do I need to re-phrase my question ?

any response please ? This was an example from Kathy's certification book. So I am inclined to believe that this is correct but not getting it how ?

class Reader extends Thread { Calculator c; public Reader(Calculator calc) { c=calc; } public void run() { synchronized(c) { try { System.outprintln("Waiting for calculation..."); c.wait(); } catch(InterruptedException e){ } } System.out.println("Total is: "+c.total()); } public static void main(String args[]) { Calculator calculator = new Calculator(); calculator.start(); new Reader(calculator).start(); new Reader(calculator).start(); new Reader(calculator).start(); } } class Calculator extends Thread { int total; public void run() { synchronized(this) { for(int i=0;i<100;i++) { total +=i; } notifyAll(); } } }

Now, in this code, I am a bit confused that how will the reader threads reach the statement .......... c.wait() ?

This is because the Calculator Thread has started and it has got a lock on its own object. So while it is doing the calculations, Reader threads will not be even get the lock on the calculator object

Hi Nikunj,

Can you mention what is happening when you are trying to run ?

Arnab

Thanks Isha for the solution. So this means you need to add a command to each item of the form. Right ?

Arnab

ok... now I am a bit confused... the original question was how to read the file from the jar...

If we are trying to read from the RMS, then there has to be a mechanism to transfer the file which is the jar to RMS location for future access..

Isn't this correct ?

Hi Adroit,

Did you manage to solve the problem ? You might want to post the code, packaging etc... for solution.

Hi Vijay,

google search.. and you will get hundreds of resources for understanding J2ME basics..

if you have specific questions, please post..

Arnab

I think you will have the same problem with CLDC 1.1 if you open few more connections.. or it could be due to implementation of the APIs for that phone..
