java - Cloudant j2se prototype throwing HTTPRequest exception -

i'm trying follow replication guide on github cloudant prototype basic 1 way connection between local couchdb , and locally running j2se app utilizing cloudant sync library.

the local datastore file being created, after running application, i'm getting runtime error - @ glance i'm little unsure of how resolve: asside cloudant code , dependancies;

this entire code app - have apache couchdb installed on machine , database called 'baseball' exists already:

import com.cloudant.sync.datastore.datastoremanager; import com.cloudant.sync.datastore.datastore; import com.cloudant.sync.replication.*; import com.cloudant.sync.notifications.*; import com.google.common.eventbus.subscribe; import java.util.concurrent.countdownlatch; import java.io.*; import java.net.*; //https://github.com/cloudant/sync-android/blob/master/doc/replication.md public class cloudapp{     public static void main(string [] args) throws exception{         file path = new file("datastores");         system.out.println(path.getabsolutepath());         datastoremanager manager = new datastoremanager(path.getabsolutepath());          uri uri = new uri("http://127.0.0.1:5984/baseball");         datastore ds = manager.opendatastore("my_datastore");          // create replictor replicates changes remote         // database local datastore.         replicator replicator = replicatorfactory.oneway(uri, ds);          // use countdownlatch provide lightweight way wait completion         countdownlatch latch = new countdownlatch(1);         listener listener = new listener(latch);         replicator.geteventbus().register(listener);         replicator.start();         latch.await();         replicator.geteventbus().unregister(listener);         if (replicator.getstate() != replicator.state.complete) {             system.out.println("error replicating remote");             system.out.println(listener.error);         }     }  }  class listener {      private final countdownlatch latch;     public errorinfo error = null;      listener(countdownlatch latch) {         this.latch = latch;     }      @subscribe     public void complete(replicationcompleted event) {         latch.countdown();     }      @subscribe     public void error(replicationerrored event) {         this.error = event.errorinfo;         latch.countdown();     } } 

and runtime error log outputs:

many help. regards, reece.

i noticed in other threads regarding stub related apache commons httpclient related stuff, android library build path order can have effect. trying run within eclipse & sure enough - after opened build path editor , moved android.jar last on build path, run time error went away.
