In the case where a tomcat connector http or https port fails to initialize due
to a "java.net.BindException: Address already in use" exception, I'd either
like to configure things to cause the JBoss server to fail to initialize and
shutdown, or somehow detect this from within our web app.
The problem we have is that JBoss still initializes and just displays this
issue as a warning only, and so although the server starts, the web application
is not available on all configured ports.
I've tried making JMX calls to find the connector mbeans (type=Connector), but
the first connector that fails is still found via JMX and I haven't figured out
a way to tell if it's valid. Also, I've tried looking for mbeans of
"type=ProtocolHandler", but they don't seem to be instantiated until after the
web applications are initialized, and I'd like to be able detect this issue
while our servlet is initializing.
Any help on this issue would be greatly appreciated.
The error logged during initialization is:
2006-05-24 14:17:54,418 ERROR [org.apache.coyote.http11.Http11Protocol] Error
