public void registerTemplateEngine(String templateExtension,
                                   TemplateEngine templateEngine)

Registers the given template engine.

Will add the engine to the existing list of known engines.

Parameters:

templateExtension - filename extension (eg. .jsp, .ftl, .vm).

templateEngine - the engine.

getTemplateEngine

public TemplateEngine getTemplateEngine(Template template,
                                        String templateTypeOverride)

Gets the TemplateEngine for the template name. If the template name has an extension (for instance foo.jsp), then this extension will be used to look up the appropriate TemplateEngine. If it does not have an extension, it will look for a Configuration setting "struts.ui.templateSuffix" for the extension, and if that is not set, it will fall back to "ftl" as the default.

Parameters:

template - Template used to determine which TemplateEngine to return

templateTypeOverride - Overrides the default template type

Returns:

the engine.
