answer is yes, it is possible. Others have done it successfully. If you want a place to start, take a look at host manager servlet http://svn.apache.org/viewvc/tomcat/tc6.0.x/trunk/java/org/apache/catalina/manager/host/HostManagerServlet.java?view=annotate
Note, this doesn't imply that you have to do it over HTTP, implement it any way you want to fit your environment

Dear Forum, Is it possible to dynamically add/remove hosts through code without restarting Tomcat (6.0)? I am writing an application that creates new websites on the fly (eg. website1.mydomain.com, website2.mydomain.com etc). Each of these websites will exist in a separate directory on the server - this is so they may be upgraded independently in the future. 1. I have considered programatically editing server.xml, but have ruled this out since it would require restarting Tomcat afterwards (and hence downtime of existing sites). 2. I have also considered running multiple instances of Tomcat, but each instance would have to use a different TCP port. In the absence of any additional software, this would mean I would need lots of external IPs. 3. I have looked at the 'tomcat-manager' app (and considered interfacing with it via HTTP) but the start function does not seem to work and from what I have read, this app is no longer supported? Would anybody be able to advise me on the best approach please? I have not ruled out any of the above options completely if they can be implemented reliably and without restarting the server. Thank you in advance! Richard.
