Java Logger doesn't write into file

Question

I'm trying to configure Logger to write to a file in the application configuration folder, but I'm not able to figure how to do so, here is the function I use to configure the logging output at program startup:

private void ConfigureLogger(){
    Logger logger = Logger.getLogger(FormLogin.class.getName());

    try{
        FileHandler handler = new FileHandler(getConfigurationFolder()+"\\application.log", 10, 1, true);

        logger.addHandler(handler);
    }
    catch(IOException e){

    }
    logger.log(Level.SEVERE, "test message");
}

The application.log file is created, but the test log is not written in it but in the console application.

@Joel replace {} with { throw new RuntimeException(e); } — artbristol

Could you try:

FileHandler handler = new FileHandler("D:/temp/application.log", 8096, 1, true);

Parameters:

pattern - the pattern for naming the output file
limit - the maximum number of bytes to write to any one file
count - the number of files to use
append - specifies append mode

That works, but why can't I write to a file in the configuration folder (C:\Users\Joel\.application)? I already have a function that writes a configuration file in there and it works right.

Can you post your exact code on this? (or atleast the relevant part?)
