Something like Environment.StackTrace in .Net.
BTW, Thread.dumpStack() is not what I want - I want to get the stacktrace back, not print it out.
How do I determine if a Scala module is opened as script or if it is regularly imported?
This question is about the same issue as previous Python question:
how do I determine whether a python script is imported as module or run as script?
but for Scala
This time I want to get the annotation from the thrown exception.
My example code is like this:
public class P {
@MyAnnotation(stringValue = "FirstType", intValue = 999)
public void test() throws Exception {
// ...
throw new NullPointerException();
}
@MyAnnotation(stringValue = "SecondType", intValue = 111)
public void test(int a) throws Exception {

In C/C++ the filename is returned by FILE and line number is returned by LINE.
Java does have a getFileName(), but does not seem to have a corresponding getLineNumber().
It would be nice to be able to do something like this:
catch (Exception e) {
System.err.println(this.getFileName() + this.getLineNumber() + e.getMessage());
}
Is there a way to get the java file/line number?
Let's say there are three consecutive function calls in one try block and all of them throw the same type of exception. How can i figure out which function call threw the caught exception when handling it?
When getting a stacktrace as error report from an application that is already deployed, it would be helpful to also get the actual variable values to reconstruct the system's state at the point before the exception was thrown.
Is anything like that feasible in Java and how could one do that?
Cheers,
Max

Instead of seeing the stack trace I'm seeing:

My principal problem is how to find out whitch object type called specific method.
Is out there any solution that do no use stack trace ?
If not why such information are not avaiable ? it could be very helpfull.
Give a simple reference to a Throwable object. I want to just find out what the original class where this was thrown. I no longer am inside this class so all I have is a Throwable object that was passed in from somewhere.
When I received an exception such as IOException or RunTimeException, I can only know the line number the the class.
First of my question. Is it possible to retrieve the method name through exception?
Second, is it possible to retrieve the method and the parameter of this method by line number?
p.s. I need to know the exactly about the method name and its parameters, because I want to disting...
