Thread: Java RMI registry.bind() on Ubuntu Jaunty

hello all!

having problem rmi running on linux (i use ubuntu 9.04). maybe of faced same problem , found solution , can share me.

remoteexception each time try bind stub rmi registry. according posts read, people have problems client calls, cannot close it.

rmic code before executing , far know don't need worried setting policy file or securitymanager this.

read item a.1 in rmi faq, couldn't working. googled information read related clients trying connect existent working server (and can not working).

static ip address in network 192.168.0.101

## /etc/hosts file content:

code:

127.0.0.1 localhost  127.0.1.1 lobo-laptop

## /etc/hosts.allow file content:

code:

all: 192.168.0.111, 192.168.0.112, 192.168.0.100, 127.0.0.1, 127.0.1.1

## (trimmed , simplyfied) relevant part of code follows:

code:

//dataserver inteface extends remote.    dataserver instance = new dataserverimpl();    dataserver stub;    registry rmiregistry;         //i read in net hostname should map computer's host name,    //but tried after trying without setting property ,    //it didn't work (also tried ip addr no luck).    system.setproperty("java.rmi.server.hostname", "lobo-laptop");       try {        stub = (dataserver) unicastremoteobject.exportobject(instance));        rmiregistry = locateregistry.getregistry();             //here exception thrown.        rmiregistry.rebind("dataserver", stub);    } catch (remoteexception re) {        re.printstacktrace();        system.err.println();    }

## stub information:

code:

dataserverimpl_stub[unicastref [liveref: [endpoint:[lobo-laptop:47839](local),objid:[-31110a77:12407db5840:-7fff, -6460063892832792796]]]]

## registry information:

code:

registryimpl_stub[unicastref [liveref: [endpoint:[127.0.1.1:1099](remote),objid:[0:0:0, 0]]]]

## exception information:

code:
