<P>
The <em>EventAdapterRegistry</em> is the registry of event adapters.
If a desired adapter is not found, the adapter will be dynamically
generated when lookup is attempted. Set the <code>dynamic</code> property
to <code>false</code> to disable this feature.
<p>
This implementation first looks for an adapter in its lookup table
and if it doesn't find one looks for a standard implementation of
that adapter in the org.apache.bsf.util.event.adapters package with a
standard naming convention. The naming convention it assumes is the
following: for event listener type <tt>a.b.c.FooListener</tt>,
it loads an adapter of type
<tt>org.apache.bsf.util.event.adapters.a_b_c_FooAdapter</tt>.
If both the loading and the dynamic generation fail, then a
<code>null</code> is returned.
