Hi,
I'm working on my very first jini application and I want to develop a
"fat" service (where the work is done on the server and the client
uses a proxy).
Hence, I want to setup a nonactivatable jini service (the
implementation must be Remote and must be able to create a proxy) as
described in Jan Newmarch's book in chapter 21 using the
ServiceDescription interface.
These are the steps that I followed:
1) Start Jini HttpServer:
D:\jini\apache-river-2.2.0\lib>java -jar tools.jar -port 8080 -dir
D:\jini\apache-river-2.2.0\lib-dl
and I have obtained the following message:
Jan 16, 2012 10:11:28 PM com.sun.jini.tool.ClassServer run
INFO: ClassServer started [[D:\jini\apache-river-2.2.0\lib-dl\],
port 8080]
2) Start Reggie service using the following instruction (I'm using
reggie because I want to register my service with the reggie lookup
service):
D:\>java -Djava.security.policy=D:\policy.all -jar
D:\jini\apache-river-2.2.0\lib\start.jar
D:\start-transient-reggie.config
and I have obtained the following message:
Jan 16, 2012 10:23:12 PM com.sun.jini.reggie.RegistrarImpl init
INFO: started Reggie: c704a7fa-0540-46a4-93b1-a321bc8c50a8, [],
ConstrainableLookupLocator[[jini://pc-nume/], [null]]
(2.1)Where the start-transient-reggie.config looks as follows:
import com.sun.jini.start.ServiceDescriptor;
import com.sun.jini.start.NonActivatableServiceDescriptor;
import com.sun.jini.config.ConfigUtil;
com.sun.jini.start {
private static codebase = ConfigUtil.concat(new Object[] {
"http://";,
"localhost",
":8080/reggie-dl.jar"+"
http://","localhost",":8080/jsk-dl.jar";
}
);
private static policy = "D:\\policy.all";
private static classpath =
"D:\\jini\\apache-river-2.2.0\\lib\\reggie.jar";
private static config = "D:\\transient-reggie.config";
static serviceDescriptors = new ServiceDescriptor[] {new
NonActivatableServiceDescriptor(
codebase, policy, classpath,
"com.sun.jini.reggie.TransientRegistrarImpl",new String[] { config })
};
}
(2.2)transient-reggie.config
com.sun.jini.reggie {
initialMemberGroups = new String[] {} }
3) Afterwards I have developed the service and I have created the jar
"ServiceDescription-dl.jar", which I have put at
D:\jini\apache-river-2.2.0\lib-dl\classes where the http server is
started and which contains the classes needed by the client.
The thing is that if reggie is started then I get the following
error message:

at starter.ServiceDescription.main(ServiceDescription.java:36)
If reggie is not started, then I get no error and the service
works.
Otherwise, if I try to start reggie after my service is started I
get a similar error.

Shouldn't both services be able to run on the same server?
What have I done wrong?? I really dont't have any clue, I think I
got the concept wrong somewhere!
Best regards!
