An updated tutorial can be found here: https://www.leadtools.co...s-and-set-a-license.html

In the below example we are working in the Eclipse IDE

In order to access the LEADTOOLS Libraries and utilize the various calls and functionality,
you will need to pass them through the RasterSupport.setLicense() method for validation.

Below is an example of this code being set, along with the required references and imports:

import leadtools.*;

public class simpleOcr {
	public static void main(String[] args) {
		try {
			String licensePath = "ENTER FILE PATH TO LICENSE HERE";
			String developerKey = "ENTER STRING FROM KEY HERE"; 
			// Set your license
			RasterSupport.setLicense(licensePath, developerKey);

			//License expired check
			if (RasterSupport.getKernelExpired()) {
				System.out.println("License NOT Set Successfully");
			} else {
				System.out.println("License Set Successfully");
		catch (Exception ex) {
