Join Ketkee Aryamane for an in-depth discussion in this video Define the REST class, part of Java EE: Concurrency and Multithreading.
- [Narrator] The next step will be…to write a REST class for that transaction demo,…and then we will get hold of the ManagedExecutorService…object, which we will have to inject…through the @Resource annotation.…Let's go to the IDE.…Let's go under the REST folder, and create a class,…which we will call Transaction Resource, okay.…Let's come down and let's define…the part and addition for it.…
Okay, and this is a transaction that you're doing…so let's this time use the @POST method of the javax.…So we'll use the POST annotation,…and a simple method public string execute transactions.…Okay, and what are we going to do here?…We're going to first inject the…managed executor service object.…Right, for that let's go to concurrent resources…managed executor service and pick up the name,…the default resource, come back to IDE,…and under the transaction resource class online number 18,…I will inject that resources.…
I say lookup.…Okay.…And of course take a reference for it.…So private managed executor service, okay.…And the next thing will be of course,…
