我在下面给出了从bpm引擎获取数据的代码，但遇到了如下所述的错误。有人可以告诉我一些工作代码或帮我解决问题

// How to use paging:
// 1. If you need to dynamically calculate paging size (or) to display/find
// out the number of pages, the user has to scroll (Like page X of Y)
// Call queryTasks to find out the number of tasks it returns. Using this
// calculate your paging size (The number of taks you want in a page)
// Call queryTasks successively varing the startRow and endRow params.
// For example: If the total number of tasks is 30 and your want a paging size
// of 10, you can call with (startRow, endRow): (1, 10) (11, 20) (21, 30)
// 2. If you have fixed paging size, just keep calling queryTasks successively with
// the paging size (If your paging size is 10, you can call with (startRow, endRow):
// (1, 10) (11, 20) (21, 30) (31, 40)..... until the number of tasks returned is
// less than your paging size (or) there are no more tasks returned
if (tasksList != null) { // There are tasks
System.out.println("Total number of tasks: " + tasksList.size());
System.out.println("Tasks List: ");
Task task = null;
for (int i = 0; i < tasksList.size(); i++) {
task = (Task) tasksList.get(i);
System.out.println("Task Number: " + task.getSystemAttributes().getTaskNumber());
System.out.println("Task Id: " + task.getSystemAttributes().getTaskId());
System.out.println("Title: " + task.getTitle());
System.out.println("Priority: " + task.getPriority());
System.out.println("State: " + task.getSystemAttributes().getState());
System.out.println();
// Retrive any Optional Info specified
// Use task service, to perform operations on the task
