Hi everyone,
I am running Mac OS X 10.4.
About a week ago, I had been receiving this error using JBoss AS 4.0.3SP1:
| javax.naming.CommunicationException: Could not obtain connection to any of
these urls: 10.0.1.6:8080 and discovery failed with error:
javax.naming.CommunicationException: Receive timed out [Root exception is

But I finally fixed it after seeing some posts.
To make it work, I disabled IPv6 at kernel level, added
-Djava.net.preferIPv4Stack=true to my runtime arguments, and ran jboss with the
following command:
$ ./run.sh --host=10.0.1.6
Now, I'd like to upgrade to JBoss 4.0.4.CR2, but I receive the above error
again. I made all of the same changes I made to get 4.0.3SP1 working, but
still get the same error. I can still run perfectly with 4.0.3SP1, using the
same code and the same system.
Are there any changes I need to know about that occurred between 4.0.4.CR2 and
4.0.3SP1 that may be causing this?
Here's my code:
| public static void main(String[] args)
| {
| try
| {
|
| connectToJBoss();
|
| System.out.println(hwRemote.getHelloWorldString("TestThisString"));
| System.out.println(hwRemote.getHelloWorldString("TestAnotherString"));
|
| }
| catch (NamingException ex)
| {
| ex.printStackTrace();
| }
| }
|
| private static void connectToJBoss() throws NamingException
| {
| try
| {
| InitialContext ctx = new InitialContext();
| ctx.addToEnvironment("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
| ctx.addToEnvironment("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
| ctx.addToEnvironment("java.naming.provider.url","10.0.1.6:8080");
| hwRemote = (HelloWorld) ctx.lookup(HelloWorld.class.getName());
| }
| catch (NamingException ex) {
| throw ex;
| }
| }
|
Thanks in advance for your replies!!!
