I'm using EJB3 Timer to schedule retries of failed billing jobs.
Here's the code that schedules a billing job for retrying:
public void schedule(@NonNull final Invoice invoice, @NonNull final
BillingRetryType type) {
| Calendar twelveHoursFromNow = Calendar.getInstance();
| twelveHoursFromNow.add(Calendar.HOUR, 12);
|
| long everyTwelveHours = 12 * 60 * 60 * 1000;
|
| ctx.getTimerService().createTimer(twelveHoursFromNow.getTime(),
everyTwelveHours, new RetryData(invoice, type));
| }
I get the following exception on the last line of the method:
13:03:04,124 ERROR [GeneralPurposeDatabasePersistencePlugin] Cannot serialize:

(Exception snipped to make the post a bit shorter...)
The RetryData class is simple, it's defined as follows:
class RetryData implements Serializable {
| private static final long serialVersionUID = 1L;
|
| private Invoice invoice;
| private BillingRetryType type;
|
| public RetryData(Invoice invoice, BillingRetryType type) {
| this.invoice = invoice;
| this.type = type;
| }
|
| public Invoice getInvoice() {
| return invoice;
| }
|
| public BillingRetryType getType() {
| return type;
| }
| }
