borysd Offline Joined: 2009-11-22Does 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, tempEASuposedToBe=jxta://cbid-59616261646162614A78746150325033426F9328E59F083D855D65F748B6F87E03
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.

but it causes exception in PeerGroup NetPeerGroup = MyNetworkManager.startNetwork();

Thank you

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!
********************************* tah_mas Offline Joined: 2012-08-06I've got the same problem i.e. as soon as I set the peerID my code breaks with:
Aug 6, 2012 4:48:53 PM net.jxta.impl.endpoint.WireFormatMessageBinary$Instantiator enforceCbjxOnIncoming SEVERE: EndpointRouterMsg declared src address does not match the sender's address. tempMsgERM.getSrcAddress()=jxta://cbid-59616261646162614E504720503250331884408F6046A2521650BBCBACD41AB303, tempEASuposedToBe=jxta://cbid-59616261646162614A787461503250335BBE5BCADE2ABB3297475FFEBE0F860903
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, tah_mas
************************************* tah_mas Offline Joined: 2012-08-06ok 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...
********************************************************************************** 发现个问题，即使通过 NetworkManager.setPeerId设置了结点id，但是通过PeerGroup.getPeerID返回的确实另外一个值，说明该调用并没有起作用。。。，Why？ ********************************************************************************** Oh, my!还是忘掉MembershipService和AccessService吧！！！ ********************************************************************************** 问题基本解决，虽然对PSEMembershipService还是一知半解： 参照《Practical JXTA II》的例子Example 620 - Custom PSE Peer Group & Joining。 在开始的时候创建keystore等，首先是变量声明： // ************************ 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。
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 一个有趣的现象，在ShadowPeerGroup.java的不同版本中，getDefaultModuleImplAdvertisement方法使用的MembershipService是不同的。 v2.5版中，使用的是PSEMembershipService；v2.6版中使用的是NoneMembershipService；而v2.7版中又回到了PSEMembershipService。在《Practical JXTA II》中（P127），有这样的说明，PSE Membership Service是默认的Membership Service，虽然该书基于JXTA v2.6版本（显然与源代码冲突）。 ##################################################################### 晕了，还是不行，启动时抛异常（网上没有解决方法）： SEVERE: EndpointRouterMsg declared src address does not match the sender's address. tempMsgERM.getSrcAddress()=jxta://cbid-8A634329B1C84ABF9E489F006BDE4B9EC627F04A469202F565EB71A52CAFFDA303, tempEASuposedToBe=jxta://cbid-59616261646162614A78746150325033DD0327CEA6B0E911250B6820AF286AD703两种解决方式：
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。
我X，用v2.6版一切正常（现在连接外网rdv也没有问题了）；还是以前的观点，v2.7版问题多多，只具有参考意义。转载于:https://www.cnblogs.com/cuizhf/p/3251692.html
