Async node or JMS message ?

[freejohn22]

Hi all !
I have in my process one Node which performs a "fire and forget" operation.....I may add an Action Handler which sends a JMS message to an MDB (that does the job) or I might as well add an Asynch node that executed the biz logic.

Is there anybody who has got experience with Async nodes ? I have never used them before, I'd like to know what could be the best practice for a scenario like this...
thanks lot

both are valid options. In the case of using an mdb, you also have to configure a queue, deploy the mdb etc, write a actionhandler that puts the message in the queue. When using async nodes this is done for you. You have less control in the latter situation about priorities etc...

thanks for your answer !
seems a match "draw" between the two options....anyway in case I have already an EJB layer clustered, it could be a better choice to use the MDB apporoach , so I have already HA out of the box for this operation...?
thanks again

Yes, if you want to have robustness you should use JMS instead of the internal asynchronous support, which works well for simple applications, but not for the high end.

uhmm... internal async support IS robust since it uses ejbtimers IF you use the jBPM EE version.
