Abstract

Techniques and mechanisms for providing asynchronous web service calls in an on-demand services environment. In response to request from a remote client, a page is provided. The page has content including logic to retrieve information from a remote resource external to an on-demand services environment via at least one asynchronous web service call. A controller component of the page is loaded before rendering a response to the remote computing device. At least one web service call is sent to the remote resource with the controller component. A continuation object is returned with the controller component to release the first thread from waiting for a response to the web service call. The continuation object provides a label to be used when handling the response. The response to the web service call is received from the remote resource and processing is resumed with the continuation object.

Claims18

Dependent claims

A method of supporting asynchronous and non-blocking web service calls through an on-demand services environment, the method comprising:

receiving, by a first server computing device of one or more server computing devices of the on-demand services environment, a request from a web browser of a remote client computing device for a page associated with the on-demand services environment, wherein the page contains information stored external to the on-demand services environment in a remote resource;
facilitating preservation of resources of a pool of threads maintained by the first server computing device by:
causing, by a controller component of the page executed by a first thread running on the first server computing device, a state of the request to be persisted until the information from the remote resource is available, wherein the first thread was allocated by the first server computing device from the pool of threads;
requesting, by the controller component, the information from the remote resource by making an asynchronous, non-blocking web service call to the remote resource;
and
releasing, by the controller component, the first thread from waiting for a response to the asynchronous web service call by returning the first thread to the pool of threads;
and
when a response is received to the asynchronous, non-blocking web service call from the remote resource, resuming processing of the request by a second thread allocated from the pool of threads running on the first server computing device, including retrieving the state of the request.

5 more elements

A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors of one or more server computing devices of an on-demand services environment cause the one or more processors to:

receive a request from a web browser of a remote client computing device for a page associated with the on-demand services environment, wherein the page contains information stored external to the on-demand services environment in a remote resource;
facilitating preservation of resources of a pool of threads by:
causing, by a controller component of the page executed by a first thread, a state of the request to be persisted until the information from the remote resource is available, wherein the first thread was allocated by the first server computing device from the pool of threads;
requesting, by the controller component, the information from the remote resource by making an asynchronous, non-blocking web service call to the remote resource;
and
releasing, by the controller component, the first thread from waiting for a response to the asynchronous web service call by returning the first thread to the pool of threads;
and
when a response is received to the asynchronous, non-blocking web service call from the remote resource, resuming processing of the request by a second thread allocated from the pool of threads, including retrieving the state of the request.
