The main problem is that server needs specific configuration to connect from client to that machine and call ejbs remotelly. I have some workarounds that works: 1. In run.bat file i added following string:*set JAVA_OPTS=%JAVA_OPTS% -Djava.rmi.server.hostname=IP Where jboss runs                                                                                                                                      -Djava.rmi.server.useLocalHostname=false* 2. In jboss-service.xml i configured this : *<!––<attribute name="clientConnectAddress">IP Where jboss runs</attribute>––>* * * After this configuration everything works. I also start jboss with parameter -b 0.0.0.0,but this does not help. From Swing client *without configuration* when i try to lookup ejb with this properties : InitialContext jndi=fina2.Main.getJndiContext(); Object ref = jndi.lookup("fina2/i18n/LanguageSession");                         *Properties p=new Properties();* * * *                       * *p.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");* ** *p.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");* ** *p.setProperty(Context.PROVIDER_URL, "jnp://***IP Where jboss runs***:1099");* * * *  InitialContext jndi=new InitialContext(props); * ** ** ** *Object ref = jndi.lookup("....");* * * The following exception is thrown: javax.naming.CommunicationException: Could not obtain connection to any of these urls: *IP Where jboss runs* 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 *IP Where jboss runs*:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server *IP Where jboss runs*:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]] at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1562) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:634) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:627) at javax.naming.InitialContext.lookup(Unknown Source) at fina2.login.LoginFrame.loadLanguageList(LoginFrame.java:127) at fina2.login.LoginFrame.languagesPopupMenuWillBecomeVisible(LoginFrame.java:426) at fina2.login.LoginFrame$5.popupMenuWillBecomeVisible(LoginFrame.java:233) at javax.swing.JComboBox.firePopupMenuWillBecomeVisible(Unknown Source) at javax.swing.plaf.basic.BasicComboPopup.firePopupMenuWillBecomeVisible(Unknown Source) at javax.swing.JPopupMenu.setVisible(Unknown Source) at javax.swing.JPopupMenu.show(Unknown Source) at javax.swing.plaf.basic.BasicComboPopup.show(Unknown Source) at javax.swing.plaf.basic.BasicComboPopup.togglePopup(Unknown Source) at javax.swing.plaf.basic.BasicComboPopup$Handler.mousePressed(Unknown Source) at java.awt.AWTEventMulticaster.mousePressed(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Caused by: javax.naming.CommunicationException: Failed to connect to server *IP Where jboss runs*:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server *IP Where jboss runs*:1099 [Root exception is java.net.ConnectException: Connection refused: connect]] at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:274) at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1533) ... 34 more Caused by: javax.naming.ServiceUnavailableException: Failed to connect to server *IP Where jboss runs*:1099 [Root exception is java.net.ConnectException: Connection refused: connect] at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:248) ... 35 more Caused by: java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.<init>(Unknown Source) at java.net.Socket.<init>(Unknown Source) at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:84) at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:77) at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:244) ... 35 more *It worked fine on Jboss 4.0.5 without configuration.* * * Can anyone tell me  some kind of workaround so that to not to configure ip address ? ,because its not good that for every machine i manually change ips. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/569919#569919] Start a new discussion in JBoss Remoting at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
