Unit 10: Web Services

The nomenclature for these methods and the job status codes depends on the service and Notes
additional methods may also be provided giving more control over the life cycle of the job.
Dispatcher
The Dispatcher based services at EMBL-EBI (e.g. WSFasta, WSInterProScan, WSNCBIBlast and
WSWUBlast) provide four methods for interacting with a job:
1. A “run “ method to submit the job, this is named after the service (e.g. RunFasta for
WSFasta)

• NOT_FOUND: The job cannot be found, commonly seen when the job is no longer
available.
• ERROR: The job failed.

• DONE: Job has finished, and the results can then be retrieved.
3. Discover the available result types for a finished job (get Results).
4. Get the result of the specified type for the job (poll).
