4.0.4.CR2 with Mac

[tvanbuskirk]

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 java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to retrieve stub from server 10.0.1.6:8080 [Root exception is java.io.EOFException]]

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!!!

Seems that using 4.0.4.CR2 and installing EJB 3.0 with clustering ended this problems. New problems arise, see new posting.
