A funning Naming Problem

[eriklee]

My Jboss server(Jboss3.0 with tomcat4.0) running on a linux server,
ip is 10.23.96.218

when I start my client programming from windows use the command line like this

C:\jdk13\bin\javaw
-Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
-Djava.naming.provider.url=10.23.96.218:1099
-Djava.naming.factory.url.pkgs=org.jboss.naming doll.HomeManager

It report the following exception


javax.naming.CommunicationException. Root exception is java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused: connect
java.net.ConnectException: Connection refused: connect

at javax.naming.InitialContext.lookup(InitialContext.java:350)
at doll.HomeManager.getHome(HomeManager.java:29)


The naming part of my code look like this:

Context ctx = new InitialContext();
System.out.println(ctx.getEnvironment());
Object ref = ctx.lookup(jndi); //-----------line 29
homes.put(jndi,ref);

and System.out.println(ctx.getEnviroment()) produce following output:
{java.naming.provider.url=10.23.96.218:1099,
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory,
java.naming.factory.url.pkgs=org.jboss.naming:com.sun.enterprise.naming}


Then I do some work on my linux server(10.23.96.218).
/etc/hosts looks like

127.0.0.1 localhost.localdomain localhost

I change it to

10.23.96.218 localhost.localdomain localhost

then, I restart my jboss server
and run my test client on windows, Now it do works.

Why this happen? why need I change the hosts file?
Is this a bug of jboss ?

Redhat or RMI take your pick.

Yes, I was having the same problem as you and came across your post, tried what you did, and it worked for me as well. A strange solution that I wish I had an explanation for.
