Hi, I'm trying to get an EJB from a remote Jboss AS 5.0.1 instance. On that same machine (in a different JVM) I can get this bean without any problems using basic code such as this:
| public static void main(String[] args) throws Exception { | Context context = getRemoteInitialContext(); | Object obj = context.lookup("EJBTest/SessionBean/remote"); | } | | public static Context getRemoteInitialContext() throws NamingException { | Properties p = new Properties(); | p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); | p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); | p.put(Context.PROVIDER_URL, "jnp://localhost:1099"); | return new InitialContext(p); | } | This is all straight from the many examples and tutorials and works like a charm. However, when I try to connect from the machine next to me, using the same code (but changing localhost into the IP number), it doesn't work. I started Jboss AS with -b 0.0.0.0: | /opt/jdk1.6.0_12//bin/java -Djboss.server.log.threshold=WARN -Dprogram.name=run.sh -server -Xms128m -Xmx512m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000 -Djava.net.preferIPv4Stack=true -Djava.endorsed.dirs=/opt/jboss/lib/endorsed -classpath /opt/jboss/bin/run.jar:/opt/jdk1.6.0_12//lib/tools.jar org.jboss.Main -b 0.0.0.0 | I also confirmed that port 1099 is reachable from the other machine via telnet and nmap. E.g.: | telnet 10.0.0.2 1099 | Trying ::1... | Connected to 10.0.0.2. | Escape character is '^]'. | ??srjava.rmi.MarshalledObject|???c?>IhashlocBytest | | nmap -sT -p 1099 10.0.0.2 | | Starting Nmap 4.63a ( http://nmap.org ) at 2009-07-11 10:34 CEST | Interesting ports on 10.0.0.2: | PORT STATE SERVICE | 1099/tcp open unknown | So the host is reachable and the port is open. However, when I now execute the following from host 10.0.0.1: | public static void main(String[] args) throws Exception { | Context context = getRemoteInitialContext(); | Object obj = context.lookup("EJBTest/SessionBean/remote"); | } | | public static Context getRemoteInitialContext() throws NamingException { | Properties p = new Properties(); | p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); | p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); | p.put(Context.PROVIDER_URL, "jnp://10.0.0.2:1099"); | return new InitialContext(p); | } | I get the following exception: | log4j:WARN No appenders could be found for logger (org.jnp.interfaces.TimedSocketFactory). | log4j:WARN Please initialize the log4j system properly. | Exception in thread "main" javax.naming.CommunicationException: Could not obtain connection to any of these urls: 10.0.0.2:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server 10.0.0.2:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server 10.0.0.2:1099 [Root exception is java.net.ConnectException: Operation timed out]]] | at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1727) | at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:680) | at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:673) | at javax.naming.InitialContext.lookup(InitialContext.java:392) | at client.TestRemoteClientAccess.main(TestRemoteClientAccess.java:23) | Caused by: javax.naming.CommunicationException: Failed to connect to server 10.0.0.2:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server 10.0.0.2:1099 [Root exception is java.net.ConnectException: Operation timed out]] | at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:311) | at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1698) | ... 4 more | Caused by: javax.naming.ServiceUnavailableException: Failed to connect to server 10.0.0.2:1099 [Root exception is java.net.ConnectException: Operation timed out] | at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:281) | ... 5 more | Caused by: java.net.ConnectException: Operation timed out | at java.net.PlainSocketImpl.socketConnect(Native Method) | at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) | at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) | at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182) | at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) | at java.net.Socket.connect(Socket.java:519) | at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:97) | at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:82) | at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:277) | ... 5 more | After googling around a little, I played with the jnp.localAddress property, but this didn't really helped. Setting it to some bogus address correctly gives a binding error, but when I enter my real local IP I pretty much get the same exception as above. I wonder if anyone could help me with this or point me to documentation describing how to do this. Many thanks in advance.
