My code :
public void completeProgressTask(long taskId, Map<String, Object> data, String userId) throws InterruptedException {
BlockingTaskOperationResponseHandler responseHandler = new BlockingTaskOperationResponseHandler();
responseHandler.waitTillDone(5000);
ContentData contentData = null;
if (data != null) {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out;
try {
out = new ObjectOutputStream(bos);
out.writeObject(data);
out.close();
contentData = new ContentData();
contentData.setContent(bos.toByteArray());
contentData.setAccessType(AccessType.Inline);
bos.close();
bos = null;
} catch (IOException e) {
e.printStackTrace();
}
}
taskClient.complete(taskId, userId, contentData, operationHandler);
operationHandler.waitTillDone(5000);
}
