Hi, I am facing some issues while doing the multi server instances on the same machine using JBoss5.0.0.Beta1 on XP machine. I am able to run the same with JBoss 4.0.5GA version. I searched the threads but not able to find the solution. If any body come across this error please help me in resolving this. Here are the steps i followed (The similar steps are working fine in JBoss4.0.5GA) 1. Copied "all" server as "jboss1" and mapped the ServiceBindingManager to "ports-01" (as described in the document) 2. Copied "all" server as "jboss2" and mapped the ServiceBindingManager to "ports-02" 3. Started the jboss1 server. 4. Started the jboss2 server. Here i got the below error. | 2007-01-02 16:02:16,546 ERROR [org.apache.coyote.http11.Http11Protocol] Error initializing endpoint | java.net.BindException: Address already in use: JVM_Bind:8080 | at org.apache.tomcat.util.net.JIoEndpoint.init(JIoEndpoint.java:499) | at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:175) | at org.apache.catalina.connector.Connector.initialize(Connector.java:1024) | 5.
