I try to follow this tenet, "Minimize resource requirements of the
client." It is very generate but has a couple of implications.
1) Write client code in a way to minimize external requirements such as
additional jar files and classes.
2) Attempt to ease the programmer's burdon for coding and deployment.
#1 implies that we should not require lots of additional things for the
client code. This includes such things as the additional client code
required for Digir (I'm working on this now) and attempt to write code
which operates with multiple versions of 3rd party jars.
#2 means make the api as easy as possible and try to reduce the jar
count required for deployment.
Reducing the jar count helps in a few ways. It makes the software
easier to use because the client code doesn't need to track multiple
jars. It also makes the application faster because the class loader
doesn't have as many jar files to scan through in order to find a
If can can deliver a single client side jar which contains all the
required goodies (EcogridFactory*.class) and all the stubs I think that
would be useful. I would support having a different seperation based on
more functional lines: Query stub classes + Query client class in one
jar, Registry stub classes + Registry classes in another jar, etc.
As for the webapp having one additional class in a jar file, the overall
impact of that is rather minimal. In addition, it is not uncommon for
the server side code to require the client code anyway (EJB is like
this, but here it is not, of course.)
