Unexpected error occurred in scheduled task

I tried to run a scheduled task in my Spring-Boot application, using the default applicationConfig - I only added the annotation @EnableScheduling and configured the class with the method that is to be scheduled, per the following code sample:

@Component public class Task { @Scheduled(cron ="*/10 * * * * *") public void init() { System.out.println("QuartzConfig initialized."); System.out.println(callService()); } private String callService() { String urlService = ""; GetMethod method = new GetMethod(urlService ); String response = ""; try { client.executeMethod(method); response = method.getResponseBodyAsString(); } catch (IOException e) { e.printStackTrace(); } finally { method.releaseConnection(); } return response; } } 

However, when the task is called, the method callService returns the following error:

java.lang.NullPointerException: null 

This, quite obviously, makes me sad.

thanks for the comments I solved this added next code to init method

 public Task(){ client = new HttpClient(); client.getParams().setParameter("http.useragent", "Bacon/1.0"); }
