Launching long running process

[hubaghdadi]

Hey.

I want to launch a long running process (that will sends SMS, interact with the database) via Ajax in order not hijack the Servlet thread and the UI.

Should I use jBPM? or another strategy exists?

Thanks.

If all u want to do is to start a long running conversation for each request(click on a link)

put

<s:conversationPropagation type="none">
</s:conversationPropagation>

into your ajax enabled link (a4j:commandLink for example)

and annotate the action method with

@Begin

jBPM will do what you want.

If your use case is simple, you can achieve asynchronicity (not hijacking the servlet thread) by using JMS. The component that handles the request posts a message to a queue. Then another component (a Message Driven Bean usually) receives the message, possibly at a later time, and executes the actual business logic, without blocking the original thread.

What I want to achieve is sending a SMS to many recipients (bulk sent)

The process containing data base interactions and HTTP request and it may a long time to finish.

I don't think JMS is an option (no plans to use MOM).

You can use an asynchronous method call (look at @Asynchronous in the docs).
