Connect or not CannotConnectException that is the question ?
ecatum May 16, 2008 10:18 AMHi,
I m develloped an application which use jboss remoting and rmi.
For the server, I implement ServerInvocationHandler.
For the client, I use org.jboss.remoting.Client to communicate with the server.
I periodically make invocation from clients to the server and release the connection using disconnect().
Problem :
After a perdiod of time, the server no longer accepts client connections and clients catch this exception :
11:12:55,515 ERROR [STDERR] org.jboss.remoting.CannotConnectException: Error making invocation in RMI client invoker. 11:12:55,515 ERROR [STDERR] at org.jboss.remoting.transport.rmi.RMIClientInvoker.transport(RMIClientInvoker.java:241) 11:12:55,515 ERROR [STDERR] at org.jboss.remoting.RemoteClientInvoker.invoke(RemoteClientInvoker.java:143) 11:12:55,515 ERROR [STDERR] at org.jboss.remoting.Client.invoke(Client.java:525) 11:12:55,516 ERROR [STDERR] at org.jboss.remoting.Client.invoke(Client.java:488) 11:12:55,516 ERROR [STDERR] at org.jboss.remoting.Client.invokeOneway(Client.java:574) 11:12:55,516 ERROR [STDERR] Caused by: java.rmi.UnmarshalException: Error unmarshaling return header; nested exception java.net.SocketTimeoutException: Read timed out 11:12:55,516 ERROR [STDERR] at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:203) 11:12:55,517 ERROR [STDERR] at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:126) 11:12:55,517 ERROR [STDERR] at org.jboss.remoting.transport.rmi.RMIServerInvoker_Stub.transport(Unknown Source) 11:12:55,517 ERROR [STDERR] at org.jboss.remoting.transport.rmi.RMIClientInvoker.transport(RMIClientInvoker.java:207) 11:12:55,517 ERROR [STDERR] ... 7 more 11:12:55,517 ERROR [STDERR] Caused by: java.net.SocketTimeoutException: Read timed out 11:12:55,517 ERROR [STDERR] at java.net.SocketInputStream.socketRead0(Native Method) 11:12:55,518 ERROR [STDERR] at java.net.SocketInputStream.read(SocketInputStream.java:129) 11:12:55,518 ERROR [STDERR] at java.io.BufferedInputStream.fill(BufferedInputStream.java:218) 11:12:55,518 ERROR [STDERR] at java.io.BufferedInputStream.read(BufferedInputStream.java:235) 11:12:55,518 ERROR [STDERR] at java.io.DataInputStream.readByte(DataInputStream.java:241) 11:12:55,518 ERROR [STDERR] at sun.rmi.transport.StreamRemoteCall.executeCall(StreamRemoteCall.java:189) 11:12:55,518 ERROR [STDERR] ... 10 more
Can it be the Client connection which aren't correctly released ?
Have somebody indications where in jboss I can search the origin of the problem ?
Thanks a lot.
