How to get the method name from which the exception is thrown?

Question

I need to get the class name and the method name from which the exception is thrown. How can I do that? Thanks in advance.

My code:

private void setErrorDetails(final Throwable cause) {
    for (final StackTraceElement ste : cause.getStackTrace()) {
        System.out.println(ste.getClassName()); 
        System.out.println(ste.getMethodName()); 
    }
}

By this code, I am able to get a list of class names and method names.Out of that, how can I get the method and class name which has thrown the exception

I also tried this.

 final StackTraceElement[] stackTrace = cause.getStackTrace();
    if ((stackTrace != null) && (stackTrace.length > 1)) {
                    final StackTraceElement stElement = stackTrace[0];

                    this.className = stElement.getClassName();
                    this.methodName = stElement.getMethodName();}

This is the printed stacktrace.

arent the stack frames ordered? The exception has been thrown from the topmost one... but the cause is probbably in something in your code in the middle of this list... — V-X, Jun 06 '13 at 11:23
Actually my question is not about finding a line number. See I have a database and I need to insert the values of the methodname and classname into it. So I need to know the exact methodname and classname. And it is not a duplicate. Please do not judge by yourself. — mukund, Jun 06 '13 at 11:26
please define, what is the exact cause? Is that you haven't checked the input, is that there is some failing remote module or is that dumb user doing unsupported actions? — V-X, Jun 06 '13 at 11:59
just a comment. stack-trace is just extended log information for developer/operator. It's not an information which will tell to the outer parts of the program what happened inside... — V-X, Jun 06 '13 at 12:01
a comment after your edit (adding the stack trace): Now I think I know what you want to achieve: You want to find the method and class where the exception happened but you only want your own classes and not the ones from 3rd party libraries. You could achieve this by using the answer from Aleksander and change the loop end condition (end if the class is a third party class). But I don't see the reason - it is simply not useful since the error might be in another class - it would be better to store the whole stacktrace so that a human developer is able to understand what happened. — mschenk74, Jun 06 '13 at 13:54

The method that actually threw the initial exception is the first element in the root cause of the stack trace:

private void setErrorDetails(final Throwable cause)
{
     Throwable rootCause = cause;
     while(rootCause.getCause() != null &&  rootCause.getCause() != rootCause)
          rootCause = rootCause.getCause();

    System.out.println(rootCause.getStackTrace()[0].getClassName()); 
    System.out.println(rootCause.getStackTrace()[0].getMethodName()); 
    }
}

I am getting you..but what I am asking is "is there any way to get the name of the user defined class from which the exception is thrown" – mukund Jun 06 '13 at 11:29
What do you mean by user defined class? Could you give us an example of a stack trace and what you want from it? – Aleksander Blomskøld Jun 06 '13 at 11:52
I have edited the post with the stacktrace output. Could you please check that out? – mukund Jun 06 '13 at 12:05

This article shows how you can use LogBack to filter out packages you don't want to see in stack trace in log.

The same principle should apply in your java code, you'll just have to construct filters on class names.
