I tried to configure compressed remote calls as described in Configuration Guide section 14.2.1. See: http://www.redhat.com/docs/manuals/jboss/jboss-eap-4.2/doc/Server_Configu.... I changed jboss-service.xml to use a CompressionClient/ServerSocketFactory: | <mbean code="org.jboss.invocation.jrmp.server.JRMPInvoker" name="jboss:service=invoker,type=jrmp,socketType=CompressionSocketFactory"> | <attribute name="RMIObjectPort">4445</attribute> | <attribute name="ServerAddress">${jboss.bind.address}</attribute> | <attribute name="RMIClientSocketFactory">org.jboss.test.jrmp.ejb.CompressionClientSocketFactory</attribute> | <attribute name="RMIServerSocketFactory">org.jboss.test.jrmp.ejb.CompressionServerSocketFactory</attribute> | <depends>jboss:service=TransactionManager</depends> | </mbean> | The CompressionClient/ServerSocketFactory uses a CompressionSocket to wrap the Input/OutputStream of the client-server-socket with a java.util.zip.GZIPInput/OutputStream: | class CompressionSocket extends Socket | { | .. | /* | * Returns a stream of type CompressionInputStream | */ | public InputStream getInputStream() throws IOException | { | if (in == null) | { | in = new GZIPInputStream( super.getInputStream() ); | } | return in; | } | | /* | * Returns a stream of type CompressionOutputStream | */ | public OutputStream getOutputStream() throws IOException | { | if (out == null) | { | out = new GZIPOutputStream( super.getOutputStream()); | } | return out; | } | .. | The configuration is working. The CompressionClient/ServerSocketFactory are used. But i get an exception on the client side when i do remote calls: | java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is: | java.net.SocketTimeoutException: Read timed out | at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:286) | at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:184) | at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:110) | at org.jboss.invocation.jrmp.server.JRMPInvoker_Stub.invoke(Unknown Source) | at org.jboss.invocation.jrmp.interfaces.JRMPInvokerProxy.invoke(JRMPInvokerProxy.java:133) | at org.jboss.invocation.InvokerInterceptor.invokeInvoker(InvokerInterceptor.java:365) | at org.jboss.invocation.MarshallingInvokerInterceptor.invoke(MarshallingInvokerInterceptor.java:63) | at org.jboss.proxy.TransactionInterceptor.invoke(TransactionInterceptor.java:61) | at org.jboss.proxy.SecurityInterceptor.invoke(SecurityInterceptor.java:70) | at org.jboss.proxy.ejb.HomeInterceptor.invoke(HomeInterceptor.java:184) | at org.jboss.proxy.ClientContainer.invoke(ClientContainer.java:100) | at $Proxy0.create(Unknown Source) | at com.carano.cbf.partner.client._AbstractGPAktionZuordnungEJBClienthandlerBase.createRemotehandler(_AbstractGPAktionZuordnungEJBClienthandlerBase.java:68) | at com.carano.framework.abo.EJBClienthandler$EJBObjectFactory.createRemote(EJBClienthandler.java:1293) | at com.carano.framework.util.ejb.AbstractEJBObjectFactory.getRemote(AbstractEJBObjectFactory.java:704) | at com.carano.framework.abo.EJBClienthandler.getEJBhandler(EJBClienthandler.java:245) | at com.carano.framework.abo.EJBClienthandler.doSearch(EJBClienthandler.java:897) | at com.carano.framework.abo.EJBClienthandler.doSearch(EJBClienthandler.java:850) | at com.carano.framework.abo.client.AbstractClienthandler._doSearch(AbstractClienthandler.java:1063) | at com.carano.framework.abo.client.AbstractClienthandler.searchMainBOs(AbstractClienthandler.java:1018) | at com.carano.cbf.partner.client.AbstractGPAktionZuordnungClienthandlerSupport.getLastAktionsForCurrentUser(AbstractGPAktionZuordnungClienthandlerSupport.java:109) | at com.carano.cbf.partner.client.AbstractGPAktionZuordnungEJBClienthandler.getLastAktionsForCurrentUser(AbstractGPAktionZuordnungEJBClienthandler.java:80) | at fleet.client.gui.FleetAktionenStatusBar.checkForNewAktionen(FleetAktionenStatusBar.java:201) | at fleet.client.gui.FleetAktionenStatusBar.init(FleetAktionenStatusBar.java:116) | at fleet.client.gui.FleetAktionenStatusBar.<init>(FleetAktionenStatusBar.java:108) | at fleet.client.gui.CaramotoDesktopRootPane.createStatusBar(CaramotoDesktopRootPane.java:790) | at com.carano.framework.gui.client.masterdetail.AbstractDesktopRootPane.jbInit(AbstractDesktopRootPane.java:368) | at com.carano.framework.gui.client.masterdetail.AbstractDesktopRootPane.<init>(AbstractDesktopRootPane.java:338) | at fleet.client.gui.CaramotoDesktopRootPane.<init>(CaramotoDesktopRootPane.java:274) | at fleet.client.gui.CaramotoMDIFrame$1.<init>(CaramotoMDIFrame.java:134) | at fleet.client.gui.CaramotoMDIFrame.createDesktopRootPane(CaramotoMDIFrame.java:134) | at com.carano.framework.gui.client.masterdetail.AbstractDesktopFrame.createRootPane(AbstractDesktopFrame.java:158) | at javax.swing.JFrame.frameInit(JFrame.java:241) | at javax.swing.JFrame.<init>(JFrame.java:164) | at com.carano.framework.gui.client.masterdetail.AbstractDesktopFrame.<init>(AbstractDesktopFrame.java:134) | at fleet.client.gui.CaramotoMDIFrame.<init>(CaramotoMDIFrame.java:41) | at fleet.client.gui.Main.<init>(Main.java:243) | at fleet.client.gui.Main.main(Main.java:394) | Caused by: java.net.SocketTimeoutException: Read timed out | at java.net.SocketInputStream.socketRead0(Native Method) | at java.net.SocketInputStream.read(SocketInputStream.java:129) | at java.net.SocketInputStream.read(SocketInputStream.java:182) | at java.util.zip.CheckedInputStream.read(CheckedInputStream.java:42) | at java.util.zip.GZIPInputStream.readUByte(GZIPInputStream.java:205) | at java.util.zip.GZIPInputStream.readUShort(GZIPInputStream.java:197) | at java.util.zip.GZIPInputStream.readHeader(GZIPInputStream.java:136) | at java.util.zip.GZIPInputStream.<init>(GZIPInputStream.java:58) | at java.util.zip.GZIPInputStream.<init>(GZIPInputStream.java:68) | at org.jboss.test.jrmp.ejb.CompressionSocket.getInputStream(CompressionSocket.java:72) | at sun.rmi.transport.tcp.TCPConnection.getInputStream(TCPConnection.java:85) | at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:226) | ... 37 more | Thanks for help!
