> Class loader considerations
>
> Most Servlet Engines use a special class loader for Servlets to be able to
> automatically reload a Servlet when it is modified. This class loader
> handles all class files located in a special directory, typically named
> servlets. A common mistake among new Servlet developers is to also put
> helper classes, such as the connection pool classes described here, in the
> servlets directory. This doesn't work at all when static variables are
> involved since the special class loader creates a separate class instance
> for each Servlet. To avoid this problem you should place all helper
classes
> in the regular CLASSPATH used by the Servlet Engine. How you set the
> CLASSPATH varies between Servlet Engines so read the documentation for the
> product you use.
