Which tag can be used to initialize the Tiles definition factory in Struts framework?
The <tiles:initComponentDefintions/> tag is used to initialize the Tiles definition factory. This tag is evaluated only once or not at all if the factory has already been initialized by other means. The <tiles:initComponentDefinition/> has no body and supports two attributes:
* file : The file containing your Tile definitions.(Required)
* classname : The fully qualified classname of the definition factory being initialized. This class, if specified, must implement the org.apache.struts.tiles.DefinitionFactory.(Optional)
