Hi, I've just refactored few of my t5 apps to rename package org.apache.tapesrty to org.apache.tapesrty5
It was very tiresome to do it for all classes one by one, so I tried a trick and it worked. This works for me in eclipse, it might be also used in other tools. 1. remove tapestry dependancy from the project (from pom or otherwise) 2. create the package org.apache.tapestry inside your source 3. use refactor rename on that package 4. delete the package from the source after that there are few thigs to do also: TapestryConstants was split into few classes org.apache.tapestry5. BindingConstants (PROP, LITERAL) MetaDataConstants (RESPONSE_CONTENT_TYPE...) PersistenceConstants SymbolConstants (PRODUCTION_MODE) org.apache.tapestry5.internal InternalConstants (TAPESTRY_APP_PACKAGE_PARAM...) PageRenderSupport was renamed to RenderSupport hope someone finds this useful :) Davor Hrg
