Re: The way Apache is restarted and the WO adaptor & MacOSX 10.3 Server deployement

Hi Chuck,

Who has taken the plunge and converted? What are the drawback? We very 
often deploy the same application multiple times for different 
customers i.e. the same exe but multiple application in monitor. Form 
what I have read this does not work in JBoss or am I mistaken?
