The chat feature would be a great way to prototype the integration and to give OFBiz another feature that I'm sure many people are looking for.

Hi Richard,Thanks for getting in touch with us, it's always good to hear from other ASF projects.I agree that an integration between the two projects could be quite interesting, and could actually be an extremely useful means of facilitating system<->user and user<->user communication. Here's a few thoughts:About ECAs:ECAs are pretty straight forward: when an Event occurs, if the Condition(s) are met then Action(s) are performed. The Events supported currently are Entity (EECA) events which basically correspond to database record CRUD events, Service (SECA) events which correspond the various stages of a given service's invocation (invoke, validate, commit, return, etc.) and Mail (MECA) events which occur when an email is received. Conditions are defined against whatever context is will be available when the event occurs, the record fields for an EECA, the in/out parameters for a SECA and the email contents for a MECA (from, to, subject, etc.) Actions are just OFBiz services to be invoked when the conditions are met.Sending event notifications:ECAs are the way to go for this and we'd just define services to be used as actions which send the message to ESME. You'd probably create a single generic service that is used to send any message and then use that service within other services for sending specific messages e.g. an ECA would invoke sendPurchaseOrderChangeNotification which would prepare the message contents and call sendEsmeMessage to actually send the message.Receiving messages:For this we could either create a new type of ECA specifically for ESME messages or perhaps even generalize MECAs to support any type of message so that it stands for Message rather then Mail. ECAs would then be defined and evaluated when an ESME message is received and service actions invoked to handle any processing and responses that need to occur.Additionally as part of the sending/receiving process we'd probably want to store the messages an CommunicationEvent records but that should be pretty straightforward using the existing services that are available. For storing each user's ESME address we'd just use the ContactMech entity with a new ContactMechType.For chat I guess things will be a little more complicated because OFBiz would want to play some sort of a role in logging messages and as Hans mentioned restricting communication between parties depending on there roles and permissions within the system. I'm also assuming that ESME is only concerned with sending and receiving messages so the responsibility of managing things like this and other chat features (chat buddies, rooms, status, etc.) would fall upon the chat client rather than ESME?But anyway I hope some of this is helpful and although I don't really have any time to spare at the moment to work on an integration, I just wanted to send something along to let you know that I think an integration would be quite useful and that there is some interest among the community.Regards Scott HotWax Media http://www.hotwaxmedia.com On 27/11/2009, at 9:19 PM, Richard Hirsch wrote:if you would like to work with us to get this implemented, you are very welcome.Of course. We have a test server in the cloud that we can use and REST APIs to create messages. We have also various clients (Javascript, AIr client, etc.) that users can also use to view status messages from different sources.What I don't know is how the integration with OFBiz would look like. Iread about ECAs but didn't find very many details. Ideal would to useECAs (when I understand them correctly) to use ESME's REST API to sendmessages.What are the next steps? Should I create a wiki page in the ESME wikispace where we can discuss this? D.

I'm one of the Project Leads for the Apache Incubator Project ESME (Enterprise Social Messaging Experiment)(http://incubator.apache.org/esme/ ) and I was thinking about how ESMEmight be integrated into OFbiz. I'm assuming that ECAs are probably the best place to start but I didn't find enough information. There are various integration possibilities / use cases. A fewexamples: a purchase order is changed and a short message is sent to those in ESME who are interested or the user makes an enquiry about aparticular material and OFBiz sends a short message via ESME with a status.
