I guessed it has something to do with classpath. The fact that Browser
could read my entries support this.

I used the out of box "launch-all" with one little modification. As a
ClassServer is also started with it I added to its dir list mine, the
place from where I intend to publish my xxx-dl.jars.

The probably problematic part how I start my application components.
There is a little server that discovers registrars (the one launched
by "launch-all") and register my service with it.

My service is who locate and works with the space (that is also
launched by "launch-all"). Two of its methods do read/write to the
space (I want to explore this scenario, not letting direct access
"final" clients to space).

My client calls my service's methods and the service's read to space
that fails, while the write is fine.

As server and client started from my IDE I checked settings and
found the classes dir was in the classpath (no surprise, usually this
default is appropriate, but certainly not now...). Now I changed that to
use the jars I built based on examples in Newmarch's guide.

I'm going to revise these jars, they're in suspect, I guess.

Thanks for your help!
