I'm using JBoss 4.0.1sp1 and j2sdk 1.4.2-10 on Windows XP. When I start JBoss using "run -b 192.168.0.1" (I get the same error without the -b option) I'm getting the following error: | javax.naming.CommunicationException: Failed to connect to server ${jboss.bind.address}:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server ${jboss.bind.address}:1099 [Root exception is java.net.UnknownHostException: ${jboss.bind.address}: ${jboss.bind.address}]] | The following code... System.out.println("Context.PROVIDER_URL: "+servletContext.getInitParameter(Context.PROVIDER_URL)); | ... prints... 2006-08-23 17:46:20,763 INFO [STDOUT] Context.PROVIDER_URL: jnp://${jboss.bind.address}:1099 | In the boot log I see... 17:44:14,648 DEBUG [ServiceConfigurator] BindAddress set to 192.168.0.1 in jboss:service=Naming | ... and the code... System.out.println("jboss.bind.address:"+System.getProperty("jboss.bind.address")); | ... prints... 2006-08-23 17:46:20,763 INFO [STDOUT] jboss.bind.address: 192.168.0.1 | I assume I have a configuration error somewhere because I just redeployed the ear without changing any code that could have caused this. I've run into this before and I ended up deleting JBoss and started with a clean install. I'd prefer to know how I messed up JBoss to get the ServletContext to use the literal string "${jboss.bind.address}" instead of the real address.
