How can I know where a Null Pointer Exception originated?

Question

I had a problem making a Blackberry app. I found some guy who made a tutorial which did what I attempted with mine. I copied the code of the tutorial's app to try and recreate it, just to see it in action. The result: Null Pointer Exception.

I want to know what is triggering this. How can I?

You can view the stacktrace if you catch Throwable instead of catching Exception or any subclass of Exception. e.g.

try
{
   //some code
}
catch(Throwable t)
{
    //Will automatically show a stacktrace in eclipse.  
    //I believe on a real device it will put the stacktrace in the eventlog.  
}
