Re: Problem running a jini service

Hi,

(1) The content of serviceDesc.config.


    import net.jini.core.discovery.LookupLocator;
   import net.jini.discovery.LookupDiscovery;
   import net.jini.core.entry.Entry;
   import java.io.File;
   import com.sun.jini.config.ConfigUtil;

   ServiceDescription
   {
       localhost = ConfigUtil.getHostName();
       port = "8080";
       directory = "/classes";
       file = "ServiceDescription-dl.jar";
codebase = ConfigUtil.concat(new String[] { "http://";, localhost, ":", port, directory, "/", file } ); // codebase = "http://192.168.1.13:8080/classes/starter.ServiceDescription-dl.jar";; 

       policy = "policy.all";
       classpath = "ServiceDescription-start.jar";
       implClass = "starter.FileClassifierStarterImpl";
serverConfigArgs = new String[] {"file_classifier_server.config"}; 
   }


   AdvertDescription
   {
       entries = new Entry[] {};
       groups = LookupDiscovery.ALL_GROUPS;
       unicastLocators = new LookupLocator[] { // empty };

   serviceIdFile = new File("serviceId.id");
   }


(2) file_classifier_server.config

   import net.jini.jeri.BasicILFactory;
   import net.jini.jeri.BasicJeriExporter;
   import net.jini.jeri.tcp.TcpServerEndpoint;

   FileClassifierServer
   {
exporter = new BasicJeriExporter(TcpServerEndpoint.getInstance(0), new BasicILFactory()); 
   }

Best regards,
Alina.

Can you include the contents of your services config files, if any, please?
Both services should be able to run quite happily on the same server. The port in use error can, off the top of my head, either be the HTTP port or the port that River uses for discovery (reggies port). So the first thing I would look for would be to make sure you're not accidentally attempting 
to start a second HTTP service.

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.**NonActivatableServiceDescripto**r;
     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
NonActivatableServiceDescripto**r(
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:

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!
