JAIN SIP APIとNIST実装を使用したPeerUnavailableException

Question

JAIN SIP 1.2とNIST実装を使用して簡単なSIPアプリケーションを構築しようとしています。私は私のIDEとしてEclipseでJavaSE1.7を使用しています。 問題：SipStackオブジェクトを構築しようとすると、javax.sip.PeerUnavailableExceptionが発生します。

私の主なクラス：

package net.bezeqint.sip.enp; 

public class ListenerMain { 

    public static void main(String[] args) { 

     try { 
      System.out.println("Creating ExampleListener..."); 
      ExampleListener listener = new ExampleListener(); 
     } catch (Exception e) { 
      e.printStackTrace(); 
      System.exit(-1); 
     } 
    } 
} 

マイ問題のクラス（IはSIPスタックオブジェクトを構築れるから1）：

package net.bezeqint.sip.enp; 

import javax.sip.*; 
import javax.sip.message.*; 
import javax.sip.header.*; 
import javax.sip.address.*; 
import javax.sip.address.URI; 

import java.net.*; 
import java.util.*; 

public class ExampleListener implements SipListener { 

    private SipFactory mySipFactory; 
    private SipStack mySipStack; 
    private ListeningPoint myListeningPoint; 
    private SipProvider mySipProvider; 
    private MessageFactory myMessageFacory; 
    private HeaderFactory myHeaderFactory; 
    private AddressFactory myAddressFactory; 
    private Properties myProperties; 
    private String myIP; 
    private int myPort = 5060; 

    public ExampleListener() throws Exception { 

     mySipFactory = SipFactory.getInstance(); 
     mySipFactory.setPathName("gov.nist"); 

     // create factories 
     myMessageFacory = mySipFactory.createMessageFactory(); 
     myHeaderFactory = mySipFactory.createHeaderFactory(); 
     myAddressFactory = mySipFactory.createAddressFactory(); 
     // create a Properties object to pass as an argument to the createSipStack() method 
     myProperties = new Properties(); 
     myProperties.setProperty("javax.sip.STACK_NAME","myStack"); 
     // test 
     // myProperties.setProperty("javax.sip.IP_ADDRESS","192.168.1.1"); 

     System.out.println("Creating SipStack..."); 
     mySipStack = mySipFactory.createSipStack(myProperties); 
     System.out.println("SipStack created!"); 

     // get our IP address to be used when creating the ListeningPoint 
     myIP = InetAddress.getLocalHost().getHostAddress(); 

     myListeningPoint = mySipStack.createListeningPoint(myIP, myPort, "udp"); 

     mySipProvider = mySipStack.createSipProvider(myListeningPoint); 

     mySipProvider.addSipListener(this); 


     // begin building a request 
     Address destAddress = myAddressFactory.createAddress("sip:registrar.ocean.com"); 
     Address addressOfRecord = myAddressFactory.createAddress("sip:peter@ocean.com"); 
     Address contactAddress = myAddressFactory.createAddress("sip:peter@169.254.153.60"); 

     // convert address to URI object 
     URI myRequestURI = destAddress.getURI(); 

     // create headers 
     ArrayList viaHeaders = new ArrayList(); 
     ViaHeader myViaHeader = myHeaderFactory.createViaHeader("Peterpc.ocean.com" 
       , 5060, "udp", "z9hG4bKnashds7"); 
     viaHeaders.add(myViaHeader); 

     MaxForwardsHeader myMaxForwardsHeader = 
       myHeaderFactory.createMaxForwardsHeader(70); 

     ToHeader myToHeader = myHeaderFactory.createToHeader(addressOfRecord, null); 

     FromHeader myFromHeader = myHeaderFactory.createFromHeader(addressOfRecord, "456248"); 

     CallIdHeader myCallIDHeader = myHeaderFactory.createCallIdHeader("843817637684230@998sdasdh09"); 

     CSeqHeader myCseqHeader = myHeaderFactory.createCSeqHeader(1826, "REGISTER"); 

     // create message 
     Request myRequest = myMessageFacory.createRequest(myRequestURI, "REGISTER", myCallIDHeader, myCseqHeader, myFromHeader, myToHeader, viaHeaders, myMaxForwardsHeader); 

     // add missing headers 
     ContactHeader myContactHeader = myHeaderFactory.createContactHeader(contactAddress); 
     myRequest.addHeader(myContactHeader); 

     // print the message 
     System.out.println(myRequest); 

    } 

    @Override 
    public void processDialogTerminated(DialogTerminatedEvent arg0) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void processIOException(IOExceptionEvent arg0) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void processRequest(RequestEvent arg0) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void processResponse(ResponseEvent arg0) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void processTimeout(TimeoutEvent arg0) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void processTransactionTerminated(TransactionTerminatedEvent arg0) { 
     // TODO Auto-generated method stub 

    } 
} 

コンソール出力：

I mySipFactory.createSipStack()で使用されているパス名をダブルチェックし、ビルドパスに適切にインポートされていることを確認してください。

javax.sip.PeerUnavailableExceptionの問題点は何ですか？

Answer 1

解決済み！私はorg.apache.log4jパッケージをインポートしなければなりませんでしたが、これはトリックでした。

Answer 2

Mavenを使用してプロジェクトを構築するときは、jain-sip-apiとjain-sip-riに依存していることを確認してください。
