Getting local variables

Question

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

Answer 1

I'm pretty sure you cannot get the local variables in the stacktrace as the output is built from instance of StackTraceElement which only contains, the class, the file, the method and the line number (see http://download.oracle.com/javase/6/docs/api/java/lang/StackTraceElement.html).
