I use freebsd 4.5 StABLE.
this the java version I use linux-jdk1.3.1 :
java version "1.3.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Classic VM (build 1.3.1_02-b02, green threads, nojit).
Note : I have also tried the port jdk1.3.1p5
Sorry but I cant put the source code, because it very big ( more than
3000 lines), but I can put
the main class, which provide RMI. I have build it with javac
I know that java is independet plattform, therefor my programm should
work also under freebsd,
that mean there something wrong with my installation or I have missing
to install something, there is a
configuration I must do before using java,
but I have installed java from the port collection, which install also
dependeries.
My main Program (Server) do the following:
1- run RMI Regestry at port 1099
2- then wait for a connection from the client, which a specified
command.
3- when it received command from the client it then start the simulation
Program, which should be run as Thread.
Clien Site:
the client only send the command to the server.
Source code :
