We are encountering a very strange problem with JBoss. We have a number of applications deployed to JBoss using annotated EJB3 web services. Most work 100% fine except for one. Every time we deploy an unrelated app or restart the server, this 1 application keeps dropping the web service. Redeploy that particular application again and the web service is back. I have checked the logs and not seen anything strange happen. The applications deploy and load as would be expected. Is there a possible reason for this strange behaviour as it affects only this 1 application every time.
