It seems to me the http adaptor seems like it would be the easiest to use as it just uses a URL to invoke MBean methods (how is data returned?), the SOAP adaptor seems like the best choice for a standards type solution, RMI seems like it has overhead (passing stubs, lookups...). The HTML adaptor is what it is (and it's pretty sweet). So my question is which adaptor would best suit a GUI that is running remote but needs access to MBean methods?
Are they all the same depending on what your trying to accomplish? Does anyone prefer one to the other? Just a general question, I'm prefer the SOAP one.
