Example 79 with Template

use of org.apache.velocity.Template in project hale by halestudio.

the class Templates method loadTemplate.

 * OSGi context, the template file is first copied to a temp file and then
 * loaded from there. {@link File#deleteOnExit()} is invoked on the temp
 * file <code>File</code> object after the template is merged.

 * @param variables the template context
 * @return the result of merging the template with the provided context
 * @throws TemplateException if an error occurs processing the template
