Tomcat: remote programmatic deploy?

Question

I\'d like to deploy to Tomcat programatically remotely, What are my options? I know about /manager/deploy. Is it possible over JMX? Even an MBean not commin

Answer 1

Since I found this via google as well, i want to share my deployment and undeployment solution for tomcat 7

-) as ondra-zizka pointed out it is as easy as doing a Put request to the correct URL tough the URL has changed under tomcat7 to /manager/text/deploy?path=&update=

needs to start with a forward slash e.g: /deployMe

-) you might need to set permissions for accessing manager app add this to TOMCAT_HOME/conf/tomcat-users.xml

note: the tomcat doc warns you not to give the same user access to more than one role
