Does anybody know how to initialize PSE in 2.7? If I start a rdv peer without peerId or infrastructureID then an edge peer can connect to it. As soon as I set any of IDs I'm getting the following message on the edge peer
SEVERE: EndpointRouterMsg declared src address does not match the sender's address.
tempMsgERM.getSrcAddress()=jxta://uuid-59616261646162614A78746150325033246734A29C11461D9CC3BB9B20842C1E03,

It looks to me that it wants the peerId to be generated based on a
certificate that jxse automatically generated for the WorldGroup. But if
I want the peerId to be always the same it seems that I need to
generate all artifacts for PSE myself.
How to properly initialize PSE in 2.7? I mean how it supposed to be
initialized? Examples provided with jxse 2.7 were not working for me
till I commented peerId out. I think there is some way designers of jxse
2.7 intended PSE to be used.
Thank you.

Sounds like you are deleting the keystore each time you do a restart - if 2.7 discovers that the keystore has gone then it creates a new one and generates a new certificate. Don't forget to save and restore the configuration and it helps to delete the cache.

Can you explain me how to save it?
I tried
MyNetworkConfigurator.save();
but it causes exception in
PeerGroup NetPeerGroup = MyNetworkManager.startNetwork();

Thank you
1. Delete your jxta run dir/folder
2. Create a new jxta configuration, including peer name, peerid if you need to, username, password and all of your network setup
3. Save the configuration file - this usually defaults to PlatformConfig in the jxta run dir
4. Set up the path to the keystore - there is a default
5. Start jxta.
6. Stop jxta, turn off the machine and have a cup of coffee
7. You might want to delete the cache files/dirs in the jxta run dir. Don't delete the keystore!
8. Load the configuration - you shouldn't need to set anything except
for the username and password - these are for the keystore - everything
else should be in the config file.
9. Set the keystore path if you need to ... must be the one defined above
9 Start jxta.
Read through the source of NetworkManager and NetworkConfigurtor. Believe me, it works!
I've got the same problem i.e. as soon as I set the peerID my code breaks with:

I've followed your instructions above and modified the practicaljxta2 (http://sourceforge.net/projects/practicaljxta/files/) examples Examples.B_Exploring_Connectivity_Issues.RendezVous_Jack and Examples.B_Exploring_Connectivity_Issues.Endge_Anna to reflect this but I cannot get 2.7 to work without commenting out the setPeerId (MyNetworkConfigurator.setPeerID(PID)) and removing the configurator.save() call. Unfortunately in my application I must set the peerID so this is not a solution for me.
Any advice / pointers appreciated as I'm not sure what to try next.
Thanks,

ok I think I have solved it.. I used to call NetworkConfigurator.setPeerId but changing this to NetworkManager.setPeerId fixes the problem. I'm new to jxta so not quite sure what the difference is...
// ************************ PSEMembershipService ******************************* // TODO: myPrivateKeyPassword与myKeyStorePassword必须相同 public static final String myPrincipalName = "Principal - " + refPeerGroupName; public static final String myPrivateKeyPassword = "PrivateKey Password - " + refPeerGroupName; // public static final String myPrivateKeyPassword = "a123456"; public static final String myKeyStoreFileName = "MyKeyStoreFile"; public static final String myKeyStoreLocation = ".jxta"; public static final String myKeyStorePassword = "KeyStore Password - " + refPeerGroupName; // public static final String myKeyStorePassword = "a123456"; public static final String myKeyStoreProvider = "KeyStore Provider - " + refPeerGroupName; public static final File myKeyStoreDirectory = new File(myKeyStoreLocation); public static final File myKeyStoreFile = new File(myKeyStoreLocation + File.separator + myKeyStoreFileName); public static final X509Certificate theX509Certificate; public static final PrivateKey thePrivateKey; static { // Static initialization of certificates PSEUtils.IssuerInfo forPSE = PSEUtils.genCert(refPeerGroupName, null); theX509Certificate = forPSE.cert; thePrivateKey = forPSE.issuerPkey; }
其次是配置：
// Preparing data myKeyStoreDirectory.mkdirs(); // Creating the key store FileKeyStoreManager myFileKeyStoreManager = new FileKeyStoreManager((String)null, myKeyStoreProvider, myKeyStoreFile); myFileKeyStoreManager.createKeyStore(myKeyStorePassword.toCharArray()); if(!myFileKeyStoreManager.isInitialized()) { System.out.println("Keystore is NOT initialized"); } else { System.out.println("Keystore is initialized"); } // Loading the (empty) keystore KeyStore myKeyStore = myFileKeyStoreManager.loadKeyStore(myKeyStorePassword.toCharArray()); // Setting data X509Certificate[] temp = {theX509Certificate}; myKeyStore.setKeyEntry(config.getPeerId(), thePrivateKey, myPrivateKeyPassword.toCharArray(), temp); // Saving the data myFileKeyStoreManager.saveKeyStore(myKeyStore, myKeyStorePassword.toCharArray()); // Reloading the KeyStore myKeyStore = myFileKeyStoreManager.loadKeyStore(myKeyStorePassword.toCharArray()); // Retrieving Certificate X509Certificate myCertificate = (X509Certificate)myKeyStore.getCertificate(config.getPeerId()); if(myCertificate == null) { System.out.println("X509 Certificate CANNOT be retrieved"); } else { System.out.println("X509 Certificate can be retrieved: " + myCertificate.toString()); } // Retrieving private key PrivateKey myPrivateKey = (PrivateKey)myKeyStore.getKey(config.getPeerId(), myPrivateKeyPassword.toCharArray()); if(myPrivateKey == null) { System.out.println("Private key CANNOT be retrieved"); } else { System.out.println("Private key can be retrieved: " + myPrivateKey.toString()); }
尤其需要注意的是：myPrivateKeyPassword与myKeyStorePassword必须相同，否则还是会抛出异常。按理来说不应该是这样的，怀疑可能是jxta的实现有问题，太乱，反正现在能跑起来了，先这样吧。
设置结点ID的时候，要调用NetworkConfigurator.setPeerId。

两种解决方式：
1 使用v2.6版（还需要解决无法连接外网rdv的问题）
2 参考v2.6版（主要是ShadowPeerGroup.java）,修改v2.7版，使用NoneMembershipService。
