[forge-dev] Hello World Template

[Antonio Goncalves]

Here is my code. I think it's my dependencies that are not right, because
*resourceFactory* is not injected so I get a NPE


*public class *RestEndpoint {

    @Inject
    *private *TemplateProcessorFactory *factory*;

    @Inject
    ResourceFactory *resourceFactory*;


    *public static void *main(String[] args) *throws *IOException {
        *new *RestEndpoint().doIt();
    }

    *private void *doIt() *throws *IOException {
        Resource<URL> templateResource = *resourceFactory*
.create(getClass().getResource(*"EndpointWithDTO.jv"*));
        Template template = *new *FreemarkerTemplate(templateResource);
*// Mark this resource as a Freemarker template         *TemplateProcessor
processor = *factory*.fromTemplate(template);
        Map<String,Object> params = *new *HashMap<String,Object>();
*//Could be a POJO also.         *params.put(*"name"*, *"JBoss Forge"*);
        String output = processor.process(params);
*// should return "Hello JBoss Forge".         *System.*out*
.println(output);
    }
}
