Class NonCatalogLogger

  extended by weblogic.i18n.logging.NonCatalogLogger
      extended by weblogic.logging.NonCatalogLogger

public final class NonCatalogLogger
extends NonCatalogLogger

This class provides application services for logging error messages to the WebLogic Server log. The name, location, and other properties of the log file are determined by the LogMBean for the server

All methods which take a Throwable argument, print the stack trace in the error log.

The NonCatalogLogger can be used as a static class variable and used across object instances of that class. NonCatalogLogger methods are thread safe for multiple object instances and for threads calling the log methods concurrently.

Logging from Clients:

This class is also intended for use by client code not running within a WebLogic Server. In that case, each client JVM creates its own log file. The logging properties of clients are configured with Java system properties: weblogic.log.<attributeInLogMBean>=<value>.

For logging internationalized messages, use <catalogName>Logger, generated using i18ngen. See the BEA WebLogic Server Internationalization Guide for instructions.
