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