The Unisys Eclipse logging plug-in lets you use the Apache Log4J package (http://logging.apache.org/) in your own Eclipse plug-ins. Using it involves instantiating a Logger object in your plug-in and embedding logging method calls in desired locations throughout your code.
The log messages can be written to the following modules
A file you specify in an external configuration file.
The standard Eclipse log.
The Windows Event Log.
Use the configuration file to control the activation of these various log modules. To configure the severity level for log messages refer to Setting the Log Level.
There are five levels ranging from DEBUG to FATAL.
If you are writing a feature consisting of several plug-ins, you can
Share a single log instance among all of your plug-ins.
Use a separate named log instance for each plug-in.
Use a separate named log instance for each class in each plug-in.
