Answer 1

if you are not using any logger(Log4j or oracle logger api) then you can use the below statement to print the full exception message

try{
       // statement which you want to monitor 

}catch(Exception e){
    e.printStackTrace()
    // OR System.err.println(e.getStackTrace());
    // OR System.err.println(e);
    // OR System.err.println(e.getMessage());
    // OR System.err.println(e.getCause());
}

if you are using the Logger API then use the below statement

try{

         // statement which you want to monitor 

}catch(Exception e){
  log.error(e,e); 
}
