-----------------------------------
I have developed the following {{UnknownHandler}} and using it in one of my
project (Struts + Convention), I can donate it to Struts Convention plugin,
wdyt?
{code:java}
public class TilesUnknownHandler implements UnknownHandler {
private static Logger LOG = LogManager.getLogger(TilesUnknownHandler.class);
@Override
public ActionConfig handleUnknownAction(String namespace, String
actionName) throws XWorkException {
return null;
}
@Override
public Result handleUnknownResult(ActionContext actionContext, String
actionName, ActionConfig actionConfig, String resultCode) throws XWorkException
{
ServletContext servletContext =
ServletActionContext.getServletContext();
HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
TilesContainer container = TilesAccess.getContainer(servletContext);
String namespace =
ServletActionContext.getActionMapping().getNamespace();
Set<String> definitions = buildDefinitionNames(namespace, actionName,
resultCode);
for (String definition : definitions) {
LOG.debug("Looking for tiles definition: {}", definition);
if (container.isValidDefinition(definition, request, response)) {
return new TilesResult(definition);
}
}
LOG.warn("Couldn't find tiles definition for namespace {}, action name
{} and result code {}", namespace, actionName, resultCode);
return null;
}
protected Set<String> buildDefinitionNames(String namespace, String
actionName, String resultCode) {
Set<String> definitions = new LinkedHashSet<>();
if (namespace.startsWith("/")) {
namespace = namespace.substring(1);
}
if (!Objects.equals(namespace, "") && !Objects.equals(namespace, "/")){
if (namespace.endsWith("/")) {
definitions.add(namespace + actionName);
definitions.add(namespace + actionName + "-" + resultCode);
definitions.add(namespace + resultCode);
} else {
definitions.add(namespace + "/" + actionName);
definitions.add(namespace + "/" + actionName + "-" +
resultCode);
definitions.add(namespace + "/" + resultCode);
}
}
definitions.add(actionName);
definitions.add(actionName + "-" + resultCode);
LOG.debug("Possible definition's names {}", definitions);
return definitions;
}
@Override
public Object handleUnknownActionMethod(Object action, String methodName) {
return null;
}
}
{code}

> It would be good if the struts2 website could turn the following into a
> tutorial, possibly some of the code could be included into the tile3 plugin
> but I'm not convinced at this time that should be done.
