Short RMI Question
Hi
I'm trying to get into Jackrabbit and already fail and hope someone can
give me some hints. I'm trying to set up an RMI Server and use the code
from the section "Simple Standalone RMI Server / Client"
http://wiki.apache.org/jackrabbit/ExamplesPage
My actual code looks like this
http://pastie.org/318554
The server starts correctly and if I run SecondHop.java for the first
time, that does the job, too. But if I run that a second time, I get an
Exception (see below). If I restart the rmiserver, it works again once.
I saw that others have similar problems, but I couldn't figure out how
to solve the problem, since the solution usually was "switch to rmi" and
I'm not very confident in the java world in general:)
Any help would be really appreciated

Thanks for the hint, I for now just added
remote.login();
after
reg.rebind("jackrabbit", remote);
and that does the job. I just need it for testing, the proper solution
can wait :)

Hi Christian,
Could it be that the the server sided TransientRepository is kind of
shutting down when you logout the first time and cannot connect you for
the second time ?
Maybe using a full fledged Repository setup with RepositoryConfig would
help.
