If a business exception occurs, the default behaviour will be to print the stack trace of that business exception (not the ExecutionException) and return an exit code. Note that the top-most function in the stack trace is the one that was executed last, hence, that is the function where the exception occurred. About: Sunny Solanki holds a bachelor's degree in Information Technology (2006-2010) from L.D. Throwing an exception is how the interpreter tells you an error has happened. One drawback of using Scala's wildcard character (_) in a catch clause is that you can't refer to it in your code, such as if you want to print the exception. You can explore different logging techniques in one of our previous articles. Why do we kill some animals but not others?

Asking for help, clarification, or responding to other answers. But this (using getStackTrace) itself causes "java.lang.OutOfMemoryError: PermGen space". This invocation returns an array of StackTraceElement, from which details about stack frames of the thread can be extracted. But, if you're passing this on up the chain - don't use it - you might just need to log where some exception came from. Below we have explained the usage of the method with simple example. Your trouble is that although you can suppress the stacktrace of the exception your own code threw, there is nothing you can do about the exception it will be wrapped into by the framework. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Below we have explained how we can generate StackSummary instance from the frame generator generated by walk_tb() method. We'll use our fifth example to demonstrate the usage of print_last() method. I think this is not a correct answer. In Scala a single catch block can handle all kinds of exceptions thus providing flexibility. Also, can you show how to catch multiple exceptions, and just one exception with the Scala wildcard operator (_)? Please make a note that when we used print_exception() method, it printed information about exceptions as well which was not getting printed with print_tb() method. Why do we kill some animals but not others. How can I get the current stack trace in Java? As a quick note, I just got a little bit better about how to log stack traces when writing Java or Scala code. As a part of our ninth example, we'll demonstrate the usage of walk_tb() and StackSummary.extract() methods. Asking for help, clarification, or responding to other answers.

Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. @lynks because regardless of the message I pass into the Exception constructor, 100 additional lines of wondrous stack trace joy go with it into the log, +1, disk space not an issue, it's more wanting relevant traces in the log. The problem only occurs if I try to access Exception.getStackTrace. As a part of our thirteenth and last example, we'll demonstrate the usage of walk_stack() method. We have then retrieved traceback from the error object using traceback attribute of the error object and have given it to print_tb() method which prints a stack trace. I am only interested in printing "My message". Why was the nose gear of Concorde located so far aft? @paradigmatic made a good point in suggesting to redirect rather than throw the exception; that solves the logging issue.
