org.apache.velocity.Template.merge()
The AST node structure is merged with the context to produce the final output. Throws IOException if failure is due to a file related issue, and Exception otherwise @param context Conext with data elements accessed by template @param writer output writer for rendered template @throws ResourceNotFoundException if template not foundfrom any available source. @throws ParseErrorException if template cannot be parsed dueto syntax (or other) error. @throws Exception anything else.
