How to read task using EWSJavaAPI?

I am using an EWSJavaAPI for creating task in Exchange Server but i am not getting any reference to fetch task using the same api. Below is my code add task:

    Task t=new Task(service);
    t.setSubject("Task to test in JAVA");
    t.setBody(MessageBody.getMessageBodyFromText("Test body from JAVA"));
    t.setStartDate(startTime);
    t.setDueDate(endTime);
    t.save();

And i tried below code to fetch task but this is not working :

    //Create the extended property definition.
    ExtendedPropertyDefinition taskCompleteProp = new 
    ExtendedPropertyDefinition(DefaultExtendedPropertySet.Task, 0x0000811C, 
    MapiPropertyType.Boolean);
    //Create the search filter.
    SearchFilter.IsEqualTo filter = new 
    SearchFilter.IsEqualTo(taskCompleteProp, false);                    
    //Get the tasks.
    FindItemsResults<Item> tasks = 
    service.findItems(WellKnownFolderName.Tasks, filter, new ItemView(50));

    for(Item task:tasks){
        System.out.println(task.getSubject());
        System.out.println(task.getBody());// getting error at this line
        System.out.println(task.getReminderMinutesBeforeStart());
        System.out.println(task.getReminderDueBy());
        System.out.println("=======================");

    }

error at task.getBody(); microsoft.exchange.webservices.data.ServiceObjectPropertyException: You must load or assign this property before you can read its value. at microsoft.exchange.webservices.data.PropertyBag.getPropertyValueOrException(Unknown Source) at microsoft.exchange.webservices.data.PropertyBag.getObjectFromPropertyDefinition(Unknown Source) at microsoft.exchange.webservices.data.Item.getBody(Unknown Source) at MSExchangeEmailService.readTask(MSExchangeEmailService.java:146) at MSExchangeEmailService.main(MSExchangeEmailService.java:224)

Please help, is this right approach to fetch task??

You need to load the Task first.

Add task.load() before your for loop.
