<section title="HSSF Logging facility"> <section title="HSSF Logging Facility">
<p>HSSF now has a logging facility (using
<link href="http://jakarta.apache.org/commons/logging.html">commons logging</link>)
that will record massive amounts of debugging information. Its mostly
useful to us hssf-developing geeks, but might be useful in tracking
down problems.
</p>
<p>So Why use commons logging rather than log4j? Well the following discussion from
the jakarta-general mailing list sums it up pretty well. (Thanks Morgan)
</p>
<p><em>Here's the problem, as I see it.</em>
</p>
<p><em>Suppose Commons component A decides to adopt Log4J, Commons component B
decides to adopt LogKit, and Commons component C adopts JDK1.4 logging.
They will all minimally function with the right jars in the classpath.
However you (the end-user) are left with maintaining configuration for 3
different logging APIs, which is tedious at best. When you take into
account cool features like variable log levels, Log4J appenders and the
like, you're pretty much guaranteed to swallow up useful configuration
options because sophisticated configurations are too difficult to maintain
over mutiple logging implementations.</em>
</p>
<p> <p>
<em>Contrarily, if all three Commons components use a logging facade, you can POI has a small amount of logging code embedded within it. Defining the system property
focus all your configuration efforts on one logging implementation. Sure, poi.logging will enable logging to standard out.
there is a trade-off; you don't have access to all the features, and the
interface between the facade and the implementation must be maintained. But
the benefits are not just political; they potentially make the end-users
configuration much easier.</em>
</p>
<p><em>Even if all Commons components used the same logging implementation (Log4J
for example), other projects in Jakarta-land may choose otherwise. If you
add enough Jakarta projects to your environment, you eventually end up with
the scenario described above. It's a worthwhile effort to attempt a logging
solution that plays well with the Jakarta community at large. I think in
many cases the Commons Logging component can fill that role.</em>
</p>
<p>
Refer to the commons logging package level javadoc for more information concerning how to
<link href="http://jakarta.apache.org/commons/logging/api/index.html">configure commons logging.</link>
