JBOSS EAP 5.1中远程EJB3客户端的套接字超时

Question

Invoking a very long-lasting method (> 30 minutes) of a remote EJB I was getting the following socket timeout exception:

...
Caused by: org.jboss.remoting.InvocationFailureException: Socket timed out.  Waited **1800000** milliseconds for response while calling on InvokerLocator [socket://remote_server:3873/]; nested exception is: java.net.SocketTimeoutException: Read timed out

Looking at the above stack it is clear that Jboss default timeout for invoking remote EJBs over socket transport is 30 mins (1800000 msecs). I read many topics on the web but I could not find a working solution, even trying RedHat official solution ( https://access.redhat.com/solutions/25149 ).

Answer 1

After some Jboss internals debugging (mainly related to JBoss Remoting module) I came up with the following solution:

--> define (eg by extension) a new org.jboss.remoting.transport.socket.TransportClientFactory that instatiates ClientInvoker with the new desired timeout:

public final class TestSocketClientFactory extends TransportClientFactory {

    private static final String SOCKET_TIMEOUT_IN_MILLISECS = "7200000";// 2 hours (jboss default is 30 mins)

    @SuppressWarnings({ "unchecked", "rawtypes" })
    @Override
    public ClientInvoker createClientInvoker(InvokerLocator locator, Map config) throws IOException {
        config.put(SocketClientInvoker.SO_TIMEOUT_FLAG, SOCKET_TIMEOUT_IN_MILLISECS);
        return super.createClientInvoker(locator, config);
    }
}

--> register this new factory in org.jboss.remoting.InvokerRegistry (eg in a static block):

static {
    InvokerRegistry.registerInvokerFactories("socket", TestSocketClientFactory.class, TransportServerFactory.class);
}

Hope this will help!
