Constructor.

 public  void addSourceURL(URL sourceURL) 
{
        if (sourceURLs == null) {
            sourceURLs = new ArrayList< URL >();
        }

{@inheritDoc}

 protected String[] getResourceNames(String resourceString) 
{
        return resourceString.split(",");
}

Parse the resourceString into a list of resource paths which can be loaded by the application context.

 protected String getResourceString(Map<String, String> parms) 
{
        String resourceStr = parms.get(DefinitionsFactory.DEFINITIONS_CONFIG);
        if (resourceStr == null) {

            resourceStr = "/WEB-INF/tiles.xml";
        }
        return resourceStr;
}

Derive the resource string from the initialization parameters. If no parameter DefinitionsFactory#DEFINITIONS_CONFIG is available, attempts to retrieve the deprecated org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG parameter and #LEGACY_DEFINITIONS_CONFIG . If neither are available, returns "/WEB-INF/tiles.xml".
