To ensure that the processing is executed asynchronously, we have defined a break
of 20 seconds in the
getListOfAllStudentsAs
method before executing the
JPQL queries. The following code,which is a simulation of a slow processing, shows
the contents of the method executed by the client:
@GET
@Path("getListOfAllStudentsAs")
