Class LoggerPropertiesInit

java.lang.Object
  com.sun.sgs.impl.kernel.LoggerPropertiesInit

public class LoggerPropertiesInit
extends Object

This class is used to initialize logging levels at system startup. If the system property java.util.logging.config.class is set to this class's name, the constructor for this class will be used to initialize logging levels from several sources.

Constructor Summary

LoggerPropertiesInit()
This class is instantiated if the system property java.util.logging.config.class is set to this class's name.

Method Summary

LoggerPropertiesInit

public LoggerPropertiesInit()
                     throws IOException

This class is instantiated if the system property java.util.logging.config.class is set to this class's name. Initialize logging levels according to the following rules. In each of the rules below, the input stream from the file "lib/logging.properties" from the JRE is concatenated with the "source InputStream" and used to set the logging levels with the LogManager.readConfiguration(java.io.InputStream) method:

• If the system resource specified by the property BootProperties.DEFAULT_LOG_PROPERTIES exists, and the file specified by the system property java.util.logging.config.file exists, use the concatenation of input streams of these two items (in that order) as the source InputStream.
• If one and only one of the resources mentioned above exists, use it as the source InputStream.
• If neither of the resources mentioned above exist, initialize the logging levels according to the standard rules for the LogManager as if neither java.util.logging.config.class nor java.util.logging.config.file are set. In other words, there is no "source InputStream" and the default "lib/logging.properties" file is simply used.

Note that if both resources exist as in the first scenario above, any property that is specified in both resources will retain the value of the property from the java.util.logging.config.file.

Throws:

IOException - if an error occurs reading the configuration from the source InputStream
