At our company we have have found a solution to the logging dilemma and
think FOP should do the same.
At this point there seems to be several ways to log errors within a Java
application:
1. JDK 1.4's new Logging API's
2. Log4J
3. Log Kit
4. Avalon's Loggable interface
5. Some new JDK compatible API's
The worst part about this situation is that one component might use Log4J
and another part of the same application may depend on Log Kit. So now your
logs are spread all over the place within the same application.( Our
company is writing a Swing application that had this exact problem. )
The solution is:
Logging should be done in the same way JDBC is done. There should be one
set of interfaces and multiple drivers. Log Kit and Log4J considered the
equivalent of JDBC drivers such as Oracle, DB2 etc...
We put together Trunk ( http://www.openinstitute.org/trunk/ ) as a
collection of Interfaces compatible with multiple drivers.
From the Trunk Docs:
LoggingDriver.getDriver()
* <li>Get the value of the
<tt>org.openinstitute.trunk.LoggingDriver</tt> system property,
* which must be a class that implements the {@link LoggingDriver}
interface.
Example Usage:
Logger LOGGER = LoggingDriverFactory.getDriver().getLogger(
SomeApplication.class );
LOGGER.info("Hello world!");
Now FOP can use any driver such as Log4J or Log Kit.
