Hi,

My code :
InputStream in = new FileInputStream("DocxProjectWithVelocityList.docx");

/* InputStream in = DocxProjectWithVelocityList2PDF.class
.getResourceAsStream("DocxProjectWithVelocityList.docx");*/
IXDocReport report = XDocReportRegistry.getRegistry().loadReport(
in, TemplateEngineKind.Velocity);

		// 2) Create fields metadata to manage lazy loop (#foreach velocity) for table row.
        FieldsMetadata metadata = report.createFieldsMetadata();
		// Old API 
        /*
        metadata.addFieldAsList("developers.Name");
		metadata.addFieldAsList("developers.LastName");
		metadata.addFieldAsList("developers.Mail");
		*/
        // NEW API
		metadata.load( "developers", Developer.class, true );
		
		// 3) Create context Java model
		IContext context = report.createContext();
		// Register project
		Project project = new Project("XDocReport");

I am facing exception below 👍

You need Velocity JAR and their dependencies in your classpath.
