How to send a stacktrace to log4j?

Question

Say you catch an exception and get the following on the standard output (like, say, the console) if you do a e.printStackTrace() :

java.io.FileNotFo         


        

Answer 1

Just because it happened to me and can be useful. If you do this

try {
   ...
} catch (Exception e) {
    log.error( "failed! {}", e );
}

you will get the header of the exception and not the whole stacktrace. Because the logger will think that you are passing a String. Do it without {} as skaffman said
