HttpNamingContextFactory unable to reconnect -------------------------------------------- Key: JBAS-1984 URL: https://jira.jboss.org/jira/browse/JBAS-1984 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Naming Affects Versions: JBossAS-3.2.7 Final Environment: XP Reporter: Bernd Eckenfels Assignee: Emanuel Muckenhuber Fix For: JBossAS-5.0.1.CR1 Unlike the normal JNP/RMI Connection the HttpNamingContextFactory created Context does not recover from a application server shutdown. If I repeat lookups, the exception after the application server is available again looks like this: ex: javax.naming.CommunicationException: Could not obtain connection to any of these urls: http://127.0.0.1:8080/invoker/JNDIFactory [Root exception is javax.naming.CommunicationException: Failed to connect to server http:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server http:1099 [Root exception is java.net.UnknownHostException: http: http]]] javax.naming.CommunicationException: Could not obtain connection to any of these urls: http://127.0.0.1:8080/invoker/JNDIFactory [Root exception is javax.naming.CommunicationException: Failed to connect to server http:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server http:1099 [Root exception is java.net.UnknownHostException: http: http]]] at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1363) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:575) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:568) at net.eckenfels.JNDITest.main(JNDITest.java:72) Caused by: javax.naming.CommunicationException: Failed to connect to server http:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server http:1099 [Root exception is java.net.UnknownHostException: http: http]] at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:250) at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1348) ... 3 more Caused by: javax.naming.ServiceUnavailableException: Failed to connect to server http:1099 [Root exception is java.net.UnknownHostException: http: http] at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:224) ... 4 more Caused by: java.net.UnknownHostException: http: http at java.net.InetAddress.getAllByName0(InetAddress.java:1128) at java.net.InetAddress.getAllByName0(InetAddress.java:1098) at java.net.InetAddress.getAllByName(InetAddress.java:1061) at java.net.InetAddress.getByName(InetAddress.java:958) at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:61) at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:220) ... 4 more Note the Unknown Host Exception, which looks pretty much like a destroyed or miss-parsed URL. Since the connection work with the same InitialContext instance before, the setup is correct: p.put("java.naming.factory.initial", "org.jboss.naming.HttpNamingContextFactory"); p.put("java.naming.provider.url", "http://127.0.0.1:8080/invoker/JNDIFactory"); p.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces"); p.put("jnp.disableDiscovery", "true"); Context rootCtx = (Context)new InitialContext(p); while(true) { try { // rootCtx = new InitialContext(p); Context jmxCtx = (Context)rootCtx.lookup("/jmx/rmi"); l = jmxCtx.list(""); while(l.hasMore()) { System.out.println(" - " + l.next()); } } catch (Throwable t) { System.out.println("ex: " + t); t.printStackTrace(System.out); } try{Thread.sleep(10000);}catch(Throwable t) { } } This sample code works if i uncomment the re-creation of the InitialContext, however this is neighter needed by the JNP/RMI Version nor does the exception look like sane handling. The client is using jbossall-client.jar and jdk 1.5_04. Jboss 3.2.7 is running (unmodified default profile) on 1.5, too. Problem exists with 3.2.6, too.
