JavaSpace Name

Hi all,

I start a JavaSpace. Its name is "MessageSpace". And I also have a http server, a lookup server running successfully. However, after I start a outrigger, I can't find the space with a name of "MessageSpace". The details of coding : 

1.Outrigger starting script is:
java -Djava.security.policy=config\start.policy ^
      -Djinihome=%JINI_HOME% ^
      -Dcom.sun.jini.outrigger.spaceName=MessageSpace ^
      -jar %JINI_HOME%\lib\start.jar ^
     config\start-outrigger.config

2. start-outrigger.conf is
import com.sun.jini.config.ConfigUtil;
import com.sun.jini.start.ServiceDescriptor;
import com.sun.jini.start.NonActivatableServiceDescriptor;
com.sun.jini.start {
    private static codebase = ConfigUtil.concat(new Object[] {
        "http://", 
        ConfigUtil.getHostName(), ":8088/outrigger-dl.jar"});
    private static policy = "config${/}policy.all";
    private static classpath = "${jinihome}${/}lib${/}outrigger.jar";
    private static config = "config${/}jrmp-outrigger.config";

    static serviceDescriptors = new ServiceDescriptor[] {
 new NonActivatableServiceDescriptor(
     codebase, policy, classpath,
     "com.sun.jini.outrigger.TransientOutriggerImpl",
     new String[] { config })
    };
}
3. jeri-outrigger.config is

com.sun.jini.outrigger {
    initiallookupGroups = new String[] { "jiniexample" };
      
}

4. find a JavaSpace

public class Search {
 public static void main (String[] args){
  ServiceDiscoveryManager sdm = null;
  Class serviceTypes[]={JavaSpace.class};
  Entry entries[]={new Name("MessageSpace")};
        ServiceTemplate tmpl = new ServiceTemplate(null,serviceTypes,entries);
        ServiceItem serviceItem = null;
        String groups[] = new String[1];

        groups[0] = new String(getLookupGroup());
        try{
         sdm = new ServiceDiscoveryManager(new LookupDiscovery(groups), null);
         System.out.println("start to find a service");
          try {
                    serviceItem = sdm.lookup(tmpl, null, 50000);
         } catch (InterruptedException intr) {
                    System.out.println("Interrupted...");
        }
        }catch(IOException ie){
          System.out.println("Exception in service discovery"+ie);
        }
        if(serviceItem!=null){
         System.out.println("get it");
  
        }else{
         System.out.println("can't find it");
        }
 }
 private static String getLookupGroup() {
        String group = System.getProperty("com.sun.jini.lookup.groups");
        if (group == null)
            return new String("");
        else
         System.out.println(group);
            return group;
    }

}

If ServiceTemplate is changed to ServiceTemplate tmpl = new ServiceTemplate(null,serviceTypes,null), I can find the JavaSpace. I want to find a JavaSpace whose name is "MessageSpace" instead of a general one, even I only start one JavaSpace here. Any idea?

Additionally, I use Browser service to monitor the services. After the reggie and the JavaSpace is started, I can see two services (ServiceRegistrar and JavaSpace). The JavaSpace service has two attributes (ServiceInfo and BasicServiceType). I found even I set spaceName in the outrigger starting script, the name in the ServiceInfo is still "JavaSpace". wondering how to overide JavaSpace Name?

I use JSDK1.4.2 and Jini2_0_002





Thanks
