Like with all LEADTOOLS applications you will first need to provide a valid License and Key file that needs to be passed through the RasterSupport.setLicense() method.

In the example provided below we utilize the Leadtools.pdf.jar file to rotate a page using the rotation property in our PDF Document Page Class.

Code:
import leadtools.*;
import leadtools.pdf.*;

public class simpleRotate {
	public static void main(String[] args) {
		
		try{
			
			Platform.setLibPath("C:\\LEADTOOLS 20\\Bin\\CDLL\\x64");
			
			Platform.loadLibrary(LTLibrary.LEADTOOLS);
	        Platform.loadLibrary(LTLibrary.CODECS);
	        Platform.loadLibrary(LTLibrary.DOCUMENT);;
	        Platform.loadLibrary(LTLibrary.DOCUMENT_CONVERTER);
	        Platform.loadLibrary(LTLibrary.PDF);
	        
	        //String licensePath = "C:\\LEADTOOLS 20\\Support\\Common\\License\\LEADTOOLS.LIC";
			String licensePath = "ENTER FILE PATH TO LICENSE HERE";
			String developerKey = "ENTER STRING FROM KEY HERE";
			
			// Set your license
	        RasterSupport.setLicense(licensePath, developerKey);

	        if (RasterSupport.getKernelExpired()) {
	            System.out.println("License NOT Set Successfully");
	        } else {
	            System.out.println("License Set Successfully");
	        }
	    	
	        String pdfFileName = "C:\\Users\\cthompson\\Desktop\\Leadtools.pdf";
			String outFileName = "C:\\Users\\cthompson\\Desktop\\Leadtools_test.pdf";
			
			PDFDocument document = new PDFDocument(pdfFileName);
			
			PDFFile file = new PDFFile(pdfFileName);
			
			int[] rotateAngle = {90, 180, 270};
	
			file.rotatepages(rotateAngle, 1, 1, outFileName);
			
			document.dispose();
	        
		}catch (Exception ex) {
			ex.printStackTrace();
		}
	}
}
