Process template from java backed webscript

[dreambitc]

Hi all!

I have java backed webscript and i need to process FreeMarker template file against the node in Java, using JavaScript it can be achieved using the following code:

document.processTemplate(template)
‍‍‍

How can i do the same thing in Java? I've tried create ScriptNode manually and call processTemplate method but i don't have scope object and when i call processTemplate i have NullPointerException.

Is there some solutions to solve it?

Thanks in advance!

You can use TemplateService APIs to achieve same.
public void processTemplateString(String engine,
                         String template,
                         Object model,
                         Writer out)
                           throws TemplateException

Sorry for such a long reply, thx <b>mitpatoliya</b> it works.
if anyone is interested, here is example of usage:

TemplateService templateService = serviceRegistry.getTemplateService();
// our model
Map<String, Object> model = new HashMap<String, Object>(8, 1.0f);
// modelNodeRef is the node where from we are gonna take values
model.put("document", new TemplateNode(modelNodeRef, serviceRegistry, null));
// TemplateNode allows go get node properties, assocs etc.

and also template example

<#assign props=document.getProperties()>
${props["cm:name"]
