Yet another thing from Seam. Seam components can state that if a certain class is not in the classpath, then don't deploy them. Sound like an interesting feature? | <bean name="foo" class="org.drools.Shit" load-if-class-not-available="false"/> | I think this is another example of the "ON DEMAND" mode except that the user turns off the bean by removing "drools" from the classpath.
