Java Programming

Hello there! I'm trying to get jstad running, but I'm running with some issues.
I'm using
jstatd -J-Djava.security.policy=jstatd.all.policy where this file has:
grant codebase "file:${java.home}/../lib/tools.jar" {
permission java.security.AllPermission;
};

first I was getting this message:

Could not bind /JStatRemoteHost to RMI Registry
java.rmi.ConnectIOException: non-JRMP server at remote endpoint
at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:217)
at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:171)
at sun.rmi.server.UnicastRef.newCall(UnicastRef.java:306)

at sun.tools.jstatd.Jstatd.bind(Jstatd.java:40)
at sun.tools.jstatd.Jstatd.main(Jstatd.java:126)

So I changed to port 1098 because I read somewhere here that JBoss binds the naming to 1099 but the socket to 1098 or something like that.
Tried jstatd -J-Djava.security.policy=jstatd.all.policy -p 1098
and now I get this message:
Could not bind //:1098/JStatRemoteHost to RMI Registry
java.rmi.NoSuchObjectException: no such object in table
at sun.rmi.transport.StreamRemoteCall.exceptionReceivedFromServer(StreamRemoteCall.java:247)

at sun.tools.jstatd.Jstatd.bind(Jstatd.java:40)
at sun.tools.jstatd.Jstatd.main(Jstatd.java:126)

What's wrong in jstatd commands I'm using?

Best regards and happy holidays
