For struts 2.3 I still got an old app with tiles2 which does some custom
stuff and which has issues with these changes.
* `tiles-servlet-wildcard` depends on `spring-web`. That causes spring to
be pulled in to all apps that use `struts-tiles-pluign`. Due to this I would
prefer wildcard support could be optional
* in `TilesContainerFactory.createContainerFactory()` it is necessary for
me to register `tilesContainer` in `servletContext`. Can be done like this,
would you mind adding this to `StrutsTilesContainerFactory`?
```
@Override
protected BasicTilesContainer instantiateContainer(TilesApplicationContext
applicationContext) {
CachingTilesContainer tilesContainer = new CachingTilesContainer();
ServletContext servletContext = (ServletContext)
applicationContext.getContext();
ServletUtil.setContainer(servletContext, tilesContainer);
return tilesContainer;
}
```
* in `StrutsTilesContainerFactory.getSourceURLs()` these two resource
patterns are used: `/WEB-INF/**/tiles*.xml` and
`classpath*:META-INF/**/tiles*.xml`. The 2nd one causes an exception in
WebSphere with IBM JDK. Would be nice if we could make this configurable. The
exception is `Caused by: java.net.MalformedURLException: SRVE0238E: Resource
paths should have a leading slash`
Currently I have created my own `TilesListener`, `TilesInitializer` and
`TilesContainerFactory`. With the above changes I could avoid that and just
stick to `StrutsTilesListener`.
Two minor things I noticed in showcase app:
* It logs this message: `WARN (freemarker.jsp:75) - Custom EL functions
won't be loaded because no ObjectWarpper was specified .` So it may be that
`tiles-el` along with `tiles-freemarker` are not working?
* css layout seems to be broken in firefox (surely not related to this PR,
looks good in chrome and ie11, is fixed in master branch)
