| [ecf-dev] Difficulty connecting to services using r_osgi and web sockets |
|
I have a set of OSGi services running in karaf that are using r_osgi and web sockets to make them available via http on port 80. I am able to connect to these services from a client installed on the same machine but not from computers over the internet.
I think this is due to timeout while waiting to make the connection from client to server over the Internet. I put the exceptions received on the client below. How can I increase the timeout while waiting for a connection? Thanks, Timothy Vogel The client throws the following exception after approximately 20 seconds. Exception in thread "Thread-11" java.lang.NullPointerException at ch.ethz.iks.r_osgi.transport.http.HttpChannelFactory$HttpChannel.closeSocket(HttpChannelFactory.java:194) at ch.ethz.iks.r_osgi.transport.http.HttpChannelFactory$HttpChannel$1.onClose(HttpChannelFactory.java:141) at org.java_websocket.client.WebSocketClient.onWebsocketClose(WebSocketClient.java:389) at org.java_websocket.WebSocketImpl.closeConnection(WebSocketImpl.java:412) at org.java_websocket.WebSocketImpl.closeConnection(WebSocketImpl.java:420) at org.java_websocket.WebSocketImpl.eot(WebSocketImpl.java:434) at org.java_websocket.client.WebSocketClient.interruptableRun(WebSocketClient.java:281) at org.java_websocket.client.WebSocketClient.run(WebSocketClient.java:204) at java.lang.Thread.run(Thread.java:745) When the client exits it throws the additional 2 exceptions below: !STACK 0 ch.ethz.iks.r_osgi.RemoteOSGiException: Interrupted while waiting for callback at ch.ethz.iks.r_osgi.impl.ChannelEndpointImpl.sendAndWait(ChannelEndpointImpl.java:1361) at ch.ethz.iks.r_osgi.impl.ChannelEndpointImpl.sendLease(ChannelEndpointImpl.java:749) at ch.ethz.iks.r_osgi.impl.RemoteOSGiServiceImpl.connect(RemoteOSGiServiceImpl.java:725) at org.eclipse.ecf.internal.provider.r_osgi.R_OSGiRemoteServiceContainer.doConnect(R_OSGiRemoteServiceContainer.java:551) at org.eclipse.ecf.internal.provider.r_osgi.R_OSGiRemoteServiceContainer.connect(R_OSGiRemoteServiceContainer.java:532) at org.eclipse.ecf.internal.provider.r_osgi.R_OSGiRemoteServiceContainer.getRemoteServiceReferences(R_OSGiRemoteServiceContainer.java:251) at org.eclipse.ecf.internal.provider.r_osgi.R_OSGiRemoteServiceContainer.getRemoteServiceReferences(R_OSGiRemoteServiceContainer.java:217) at org.eclipse.ecf.osgi.services.remoteserviceadmin.RemoteServiceAdmin$14.run(RemoteServiceAdmin.java:2288) at org.eclipse.ecf.osgi.services.remoteserviceadmin.RemoteServiceAdmin$14.run(RemoteServiceAdmin.java:1) at java.security.AccessController.doPrivileged(Native Method) at org.eclipse.ecf.osgi.services.remoteserviceadmin.RemoteServiceAdmin.importService(RemoteServiceAdmin.java:2284) at org.eclipse.ecf.osgi.services.remoteserviceadmin.RemoteServiceAdmin.importService(RemoteServiceAdmin.java:428) at org.eclipse.ecf.osgi.services.remoteserviceadmin.AbstractTopologyManager.handleECFEndpointAdded(AbstractTopologyManager.java:293) at org.eclipse.ecf.internal.osgi.services.distribution.BasicTopologyManagerImpl.handleEndpointAdded(BasicTopologyManagerImpl.java:104) at org.eclipse.ecf.internal.osgi.services.distribution.BasicTopologyManagerImpl.endpointChanged(BasicTopologyManagerImpl.java:181) at org.eclipse.ecf.internal.osgi.services.distribution.Activator$ProxyEndpointEventListener.deliverSafe(Activator.java:206) at org.eclipse.ecf.internal.osgi.services.distribution.Activator$ProxyEndpointEventListener.endpointChanged(Activator.java:183) at org.eclipse.ecf.osgi.services.remoteserviceadmin.EndpointDescriptionLocator$1.dispatchEvent(EndpointDescriptionLocator.java:198) at org.eclipse.osgi.framework.eventmgr.EventManager.dispatchEvent(EventManager.java:230) at org.eclipse.osgi.framework.eventmgr.EventManager$EventThread.run(EventManager.java:340) Caused by: java.lang.InterruptedException at java.lang.Object.wait(Native Method) at ch.ethz.iks.r_osgi.impl.ChannelEndpointImpl.sendAndWait(ChannelEndpointImpl.java:1357) ... 19 more 119106 ERROR org.eclipse.ecf.osgi.services.remoteserviceadmin -
