Logging app messages into another file than server.log

Hi,

Although it is a while ago a worked with version 7, i kind of remember that the logging sample bundled with the appserver show how to log to the parent logger (system messages go there as well) or a application log.

Look at the samples under logger (there is only one i think.

Hi,

The samples are usaully in the samples directory of the appserver install dir. However, this might depend on the server install.

Anyway, samples can be downloaded from:

http://developers.sun.com/prodtech/appserver/reference/codesamples/index.html

This is a zip file with all the samples stuff

The actual code in there:

// import for logging classes

import java.util.logging.*;

//Remove all handlers

Handler[] h = logger.getHandlers();

for (int i = 0; i < h.length; i++) {

logger.removeHandler(h[i]);

}

//Set it to its parent handler so that it gets NOT (by Robert) printed on the server log

// In the original sample this is set to true

logger.setUseParentHandlers(false);

The actual way of adding your own file log handler:

// Create a file handler with a string as parameter for filename

Handler fh = new FileHandler(<LOGFILENAME>);

// Create a formatter to format the logger

fh.setFormatter(new SimpleFormatter());

// Add the handler to logger instance

logger.addHandler(fh);

See the javadocs for formatting stuff,
