    Intermittent java.rmi.ConnectException

    Dok Tora Newbie

      I know there have been a million posts about these kind of errors but mine seems to happen intermittently which is still quite unacceptable for a production environment.

      This happens about half a dozen times a day. Where do I even begin to look?

      My setup:

      Box A: IP A.A.A.A with Jboss 4.2.1 on Linux

      Box B: IP B.B.B.B with Tomcat 5.5.25 on Linux

      Tomcat on Box B is started with:
      -Djava.naming.provider.url=jnp://box1:1099 -Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory -Djava.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

      and in /etc/hosts box1 is mapped to A.A.A.A

      The details of the exception:

      Tools::lookup() -> Could not discover class <MYCLASS>
      javax.naming.CommunicationException [Root exception is java.rmi.ConnectException: Connection refused to host: A.A.A.A; nested exception is:
       java.net.ConnectException: Connection timed out]
       at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:724)
       at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:589)
       at javax.naming.InitialContext.lookup(InitialContext.java:351)
       at Tools.lookup(Tools.java:17)

      Many thanks for any ideas!
      (pls don't mention firewalls. it's not that!)


      P.S. Tools::lookup() does a simple InitalContext.lookup(classname).
