I'm writing a java backed webscript and need to know the correct way to pass objects to a freemarker template for rendering. Below is my simplified code. Webscriptpublic class SampleWebScript extends AbstractWebScript{ public void execute(WebScriptRequest req, WebScriptResponse res) throws IOE

I figured it out. I was over thinking and didn't see the renderTemplate method on AbstractWebScript.

In order to render a freemarker template from a java backed webscript you need:

1. The path to your freemarker template, relative to Data Dictionary/Web Scripts Extensions/

String templatePath = "org/alfresco/demo/foo.ftl";‍

2. A Map of objects to pass to your template
The code in my last post attempts, incorrectly, to pass objects to the template by creating a new arbitrary class "SampleModel" with one property and passing it as the model argument. The correct way to do what I was attempting to do in my last post is:


Map<String, Object> model = new HashMap<String, Object>();
model.put("message", "Hello World");
‍‍‍‍

3. The Writer from WebscriptResponse
You get the writer from the response object passed to your webscript


Writer writer = res.getWriter();
‍‍‍

The whole thing looks like this:


public class SampleWebScript extends AbstractWebScript {
  
  public void execute(WebScriptRequest req, WebScriptResponse res) throws IOException {
      
      String templatePath = "org/alfresco/demo/foo.ftl";

      Map<String, Object> model = new HashMap<String, Object>();
      model.put("message", "Hello World");

      Writer writer = res.getWriter();
      
      renderTemplate(templatePath,model,writer);
  }

}

Pretty simple, once understood :wink:
