Class ErrorDialogAppender

java.lang.Object
  org.apache.log4j.AppenderSkeleton
      org.globus.cog.gridface.impl.util.ErrorDialogAppender

All Implemented Interfaces:

org.apache.log4j.Appender, org.apache.log4j.spi.OptionHandler

public class ErrorDialogAppender

extends org.apache.log4j.AppenderSkeleton

Configure this as you would any log4j appender, but it is recommended to use only for error messages because it pops a dialog up each time a logging event is received.

 Example configuration:
 
 #############
 #Root category
 #############
 log4j.rootCategory=DEBUG, ERROR-DIALOG
 log4j.debug=true
 
 #############
 # ERROR-DIALOG is an error dialog for the desktop that allows errors to be emailed
 #############
 log4j.appender.ERROR-DIALOG=org.globus.cog.gridface.impl.util.ErrorDialogAppender
 # only use for events >= WARN
 log4j.appender.ERROR-DIALOG.level=WARN
 # the pattern for the message display
 log4j.appender.ERROR-DIALOG.messageConversionPattern=%d %-5p [%t] %C{2} (%F:%L) - %m%n
 # a url to post the data to
 # this url should handle the following parameters: message, location, level, and throwable
 log4j.appender.ERROR-DIALOG.PostURL=http://some-domain.com/cgi-bin/script.cgi
 # the layout of the details display
 log4j.appender.ERROR-DIALOG.layout=org.apache.log4j.HTMLLayout
