java 7 socket listen异常

Question

I have java 7 socket listen exception during jboss initialization.

JAVA: c:\Program Files\Java\jdk1.7.0\\bin\java

17:14:15,388 INFO  [WebService] Using RMI server codebase: http://127.0.0.1:8083/
17:14:15,405 ERROR [AbstractKernelController] Error installing to Start: name=jboss:service=WebService state=Create mode=Manual requiredState=Installed
java.net.SocketException: Permission denied: listen failed

When I set JAVA_HOME to c:\\Program Files\\Java\\jdk1.6.0.26 there are no exceptions during jboss initialization.

Answer 1

My guess is that this is Windows firewall - that it's got an exception (ie a permission) for the JDK 6 binary, but not for the JDK 7 binary. I suggest you open up the Windows firewall configuration applet, check what's there (either by port or binary) and give JDK 7 the same permission.

EDIT: I suggest you get JBoss out of the equation: write a small app which simply tries to listen on port 8083 on 127.0.0.1. Try running that on both JDK6 and JDK7. If that works in both out of the box, then try varying exactly how you specify the listening port.
