| 34 | /** | |
| 35 | * Implementation of TemplateLoader that loads template from the classpath. | |
| 36 | * The "path" setting is used as a prefix for all request, so it should | |
| 37 | * end with a slash.<br> | |
| 38 | * <br> | |
| 39 | * Example: If you have <pre>classpath:templates/</pre> as a | |
| 40 | * TemplateLoaderPath and request the template "foo/bar.wm", it will search for | |
| 41 | * "templates/foo/bar.wm" in your classpath. | |
