Wildfly on Redhat 7.4

[vabara]

I am using Wildfly 8.2.1 on Redhat 7.2.  My Jms client is on an AIX machine. It is a simple lookup of JMS remoteconnection factory and it works fine.

        Properties properties = new Properties();

        properties.put(Context.SECURITY_PRINCIPAL, "user");
        properties.put(Context.SECURITY_CREDENTIALS, "password");

        properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
        properties.put(Context.PROVIDER_URL, "http-remoting://"+host+":"+port);
        InitialContext jndiContext = new InitialContext(properties);
       
        QueueConnectionFactory q = (QueueConnectionFactory)_ic.lookup( "jms/RemoteConnectionFactory" ) ;

When I move my Wildfly to a Redhat 7.4, the same client fails the lookup, and I receive a  "Operation failed with status WAITING after 5000 MILLISECONDS"

Is there any suggestion on what could be the difference?  This is only an AIX issue.  If I run the same client from Windows machine, it works fine.

Thanks,

Can you please paste the complete exception stacktrace? What vendor and version of JDK/JRE do you use on the client (and server) of this AIX system? Post the output of:

java -version

The Redhat 7.4 server running Wildfly, is using jdk 1.8.  (I am starting wildfly with -b, and there are no firewalls)

Thank you.

aix is in general quite particular platform.

can you try upgrading the JDK to latest to see if it helps.

usually they do fix lots of NIO related issues with each update.

[vabara]

Tomaz,

I upgraded the jdk on AIX machine to what i believe is the latest 1.8.

java version "1.8.0_151"

Java(TM) SE Runtime Environment (build 8.0.5.7 - pap6480sr5fp7-20171216_01(SR5 FP7))

Still the same issue.

If the host or port details are incorrect, the following +CommunicationException+ will be thrown, indicating the connection timed-out.

javax.naming.CommunicationException: Failed to connect to any server. Servers tried: [http-remoting://scalinux2:8080 (Operation failed with status WAITING after 5000 MILLISECONDS)] [Root exception is java.net.ConnectException: Operation failed with status WAITING after 5000 MILLISECONDS]

Could you check it if it is correct?

Have you confirmed that you have basic connectivity from your jboss server to scalinux2 on port 8080 (e.g. via telnet)?  Is there perhaps a firewall that is blocking that connection? Also check if connection manager is available or not.
