Serializes remote invocation objects and deserializes remote invocation
result objects. Uses Java serialization just like RMI, but provides the
same ease of setup as Caucho's HTTP-based Hessian and Burlap protocols.
HTTP invoker is a very extensible and customizable protocol.
It supports the RemoteInvocationFactory mechanism, like RMI invoker,
allowing to include additional invocation attributes (for example,
a security context). Furthermore, it allows to customize request
execution via the HttpInvokerRequestExecutor strategy.
Can use the JDK's RMIClassLoader to load classes from a given codebase,
performing on-demand dynamic code download from a remote location.
The codebase can consist of multiple URLs, separated by spaces.
Note that RMIClassLoader requires a SecurityManager to be set, like when
using dynamic class download with standard RMI! (See the RMI documentation
