My development environment is jboss 4.0.5.GA jbossws-1.0.4.GA Trying to consume remote web-services from an MDB, using "service-ref" element in the deployment descriptor as mentioned in the JBossWS User guide. While invoking a web-service method, I get the following exception. I have looked through the forums but did not find any relevant help... I have already tried to increase the timeout value to 2 minutes using StubExt class... same results. My standalone client (outside of Jboss) works fine. Here is the exception stack 13:18:47,103 ERROR [CallImpl] Call invocation failed with unkown Exception | javax.xml.soap.SOAPException: Could not transmit message | at org.jboss.ws.soap.SOAPConnectionImpl.call(SOAPConnectionImpl.java:204) | at org.jboss.ws.jaxrpc.CallImpl.invokeInternal(CallImpl.java:687) | at org.jboss.ws.jaxrpc.CallImpl.invoke(CallImpl.java:404) | at org.jboss.ws.jaxrpc.CallProxy.invoke(CallProxy.java:148) | at $Proxy73.getSipCacheStatus(Unknown Source) | at com.mycompany.enms.status.PollClusterMDB.pollCluster(PollClusterMDB.java:120) | at com.mycompany.enms.status.PollClusterMDB.onMessage(PollClusterMDB.java:144) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.invocation.Invocation.performCall(Invocation.java:359) | at org.jboss.ejb.MessageDrivenContainer$ContainerInterceptor.invoke(MessageDrivenContainer.java:495) | at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invoke(CachedConnectionInterceptor.java:158) | at org.jboss.ejb.plugins.CallValidationInterceptor.invoke(CallValidationInterceptor.java:63) | at org.jboss.ejb.plugins.AbstractTxInterceptor.invokeNext(AbstractTxInterceptor.java:121) | at org.jboss.ejb.plugins.AbstractTxInterceptorBMT.invokeNext(AbstractTxInterceptorBMT.java:173) | at org.jboss.ejb.plugins.MessageDrivenTxInterceptorBMT.invoke(MessageDrivenTxInterceptorBMT.java:47) | at org.jboss.ejb.plugins.MessageDrivenInstanceInterceptor.invoke(MessageDrivenInstanceInterceptor.java:116) | at org.jboss.ejb.plugins.RunAsSecurityInterceptor.invoke(RunAsSecurityInterceptor.java:109) | at org.jboss.ejb.plugins.LogInterceptor.invoke(LogInterceptor.java:205) | at org.jboss.ejb.plugins.ProxyFactoryFinderInterceptor.invoke(ProxyFactoryFinderInterceptor.java:136) | at org.jboss.ejb.MessageDrivenContainer.internalInvoke(MessageDrivenContainer.java:402) | at org.jboss.ejb.Container.invoke(Container.java:954) | at org.jboss.ejb.plugins.jms.JMSContainerInvoker.invoke(JMSContainerInvoker.java:987) | at org.jboss.ejb.plugins.jms.JMSContainerInvoker$MessageListenerImpl.onMessage(JMSContainerInvoker.java:1287) | at org.jboss.jms.asf.StdServerSession.onMessage(StdServerSession.java:266) | at org.jboss.mq.SpyMessageConsumer.sessionConsumerProcessMessage(SpyMessageConsumer.java:905) | at org.jboss.mq.SpyMessageConsumer.addMessage(SpyMessageConsumer.java:170) | at org.jboss.mq.SpySession.run(SpySession.java:323) | at org.jboss.jms.asf.StdServerSession.run(StdServerSession.java:194) | at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:743) | at java.lang.Thread.run(Thread.java:595) | Caused by: org.jboss.remoting.CannotConnectException: Can not connect http client invoker. | at org.jboss.remoting.transport.http.HTTPClientInvoker.useHttpURLConnection(HTTPClientInvoker.java:201) | at org.jboss.remoting.transport.http.HTTPClientInvoker.transport(HTTPClientInvoker.java:81) | at org.jboss.remoting.RemoteClientInvoker.invoke(RemoteClientInvoker.java:143) | at org.jboss.remoting.Client.invoke(Client.java:525) | at org.jboss.remoting.Client.invoke(Client.java:488) | at org.jboss.ws.soap.SOAPConnectionImpl.call(SOAPConnectionImpl.java:189) | ... 32 more | Caused by: java.net.ConnectException: Connection timed out: connect | 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.Socket.connect(Socket.java:516) | at sun.net.NetworkClient.doConnect(NetworkClient.java:152) | at sun.net.www.http.HttpClient.openServer(HttpClient.java:365) | at sun.net.www.http.HttpClient.openServer(HttpClient.java:477) | at sun.net.www.http.HttpClient.<init>(HttpClient.java:214) | at sun.net.www.http.HttpClient.New(HttpClient.java:287) | at sun.net.www.http.HttpClient.New(HttpClient.java:299) | at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(HttpURLConnection.java:796) | at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:748) | at sun.net.www.protocol.http.HttpURLConnection.connect(HttpURLConnection.java:673) | at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:840) | at org.jboss.remoting.transport.http.HTTPClientInvoker.useHttpURLConnection(HTTPClientInvoker.java:163) | ... 37 more View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990528#...
