Components : Backward Compatibility Changes

# Components to Tiles
Migration Path

## In Webapps

- Put "tiles.tld" and "tiles.jar" in WEB-INF/
- Replace all reference to 'components.tld' by 'tiles.tld' in *.jsp and *.xml files.
- Replace old package name by new one wherever you use package name (don't forget web.xml and struts-config.xml)
  - s1.struts.components --> org.apache.struts.tiles
  - s1.struts.example.component--> org.apache.struts.example.tiles
  - s1.struts.taglib.components --> org.apache.struts.taglib.tiles

## In Java code

- If some of your java code use or extends old Components classes, you need to rename imported classes :
  - s1.struts.components --> org.apache.struts.tiles
  - s1.struts.example.component--> org.apache.struts.example.tiles
  - s1.struts.taglib.components --> org.apache.struts.taglib.tiles

## Tips

- Jbuilder 5 have a tool called "package migration". You can define your own set of migration name using previously defined rules.
- Lot of tools (like HomeSite) have extended replace command.

## Very old component versions

If you use a very old component version, you also have to change some tags and names :

Deprecated | New usage
<include > | <insert >
<putAttribute > | <getAsString >
<getAttribute > | <getAsString >
< instance= > (in tag <insert > or <include >) | < definition= > (in tag <insert >)<
Default definitions file name : componentInstances.xml templateDefinitions.xml | Several possibilities : Keep same name and set it in xml-config.xml:
        <init-param>
            <param-name>
              definitions-config
            </param-name>
            <param-value>
              /WEB-INF/templateDefinitions.xml
            </param-value>
        </init-param>
Change name to new default (componentDefinitions.xml)
Components parameter names in web.xml: instances-config instances-debug | Use new names : definitions-config definitions-debug

To update your web site, replace all deprecated tags with new tags.

You can use replacement tools to search for :include to be replaced by :insert
