You mean webstart? Well, there are a few things WebStart cannot do, for
security reasons. And if I am not mistaken, listening on sockets or doing
RMI is one of them. Sorry, I do not remember, I would have to read the
documentation about that.

        fiji -eval 'print("Hello, World");'

(It should work with java -Dplugins.dir=/path/to/plugins/ -jar
/path/to/ij.jar -eval 'print("Hello, Bill");' just the same if the socket
listener is enabled.)

Ciao,
