Good Afternoon All,
I am working to convert from the Task Queue Labs API to the non-labs API
version. I am finding it slightly more difficult than I initially
anticipated. It appears that how I was adding tasks to the queue is not
compatible with the non-labs API. If I just update the imports to bring
in the new API I get the error “The method url(String) is undefined for the
type TaskOptions.Builder”. I have provide some example of my code below,
if anyone else has converted can you give me some guidance on what I am
doing wrong?
Current code, using the Labs API:
*import* *com.google.appengine.api.labs.taskqueue.Queue*;
*import* *com.google.appengine.api.labs.taskqueue.QueueFactory*;
*import* *com.google.appengine.api.labs.taskqueue.TaskOptions*;
*import* *com.google.appengine.api.labs.taskqueue.TaskOptions.Method*;
*import* *com.google.appengine.api.labs.taskqueue.TaskOptions.Builder*.*;
…
Queue add_queue = QueueFactory.getQueue(add);
…
for (int i = 1; i Item_counter; i++) {
add_queue.add(TaskOptions.Builder.url(/add?item=+ItemURL[i]).method(Method.GET));
}
Code using the non-Labs API
import com.google.appengine.api.taskqueue.Queue;
import com.google.appengine.api.taskqueue.QueueFactory;
import com.google.appengine.api.taskqueue.TaskOptions;
import com.google.appengine.api.taskqueue.TaskOptions.Method;
import static com.google.appengine.api.taskqueue.TaskOptions.Builder.*;
TaskOptions TOdefault =
com.google.appengine.api.taskqueue.TaskOptions.Builder.withDefaults();
…
for (int i = 1; i Item_counter; i++) {
TaskOptions TO = new TaskOptions(TOdefault);
TO.url(/add);
TO.param(item, itemURL[i]);
TO.method(Method.GET);
add_queue.add(TO);
}
The new code compiles and will “run”, but I get all kinds of null pointer
exceptions from the tasks when they try to run. If I switch back to the
labs API it works perfectly. Can anyone help me understand what I need to
do to either get my original code to work with the new API and/or what I did
incorrectly with the updated code?
Thanks,
Doug
