Può essere comodo avere le modifiche a classi e librerie caricate automaticamente dal vostro Tomcat. Ecco come: <Context reloadable="true" /> http://tomcat.apache.org/tomcat-6.0-doc/config/context.html Set to true if you want Catalina to monitor classes in /WEB-INF/classes/ and /WEB-INF/lib for changes, and automatically reload the web application if a change is detected. This feature is very useful during application development, but it requires significant runtime overhead and is not recommended for use on deployed production applications. That's why the default setting for this attribute is false . You can use the Manager web application, however, to trigger reloads of deployed applications on demand. enjoy /m
