RE: [workflow] new contributor
Hi, I'd also like to help with applying patches, promoting, etc. I'll at least watch this threads for now ;) Yoav Shapira Millennium Research Informatics -Original Message- From: Mike Colbert [mailto:[EMAIL PROTECTED] Sent: Thursday, July 15, 2004 12:26 AM To: Jakarta Commons Developers List Subject: Re: [workflow] new contributor Mike Colbert wrote: Would like to start looking into the possibilities of a more powerful process modeling/scripting mechanism.

RE: [workflow] new contributor
I'm going to make Colin happy :-), and go through his outstanding patches this evening (Pacific time in the US), applying what I can. :-)) Thanks, Craig. My project has its first release in a couple of weeks, so after that I will start to take a look at harvesting out re-usable stuff and submitting that back.

RE: [workflow] new contributor
I have used commons-workflow on a couple of projects - using it right now in fact. I'm using it for two purposes which are I think a little beyond the original scope: 1) As a lightweight RPC mechanism, to locate and run server activities from any arbitrary client (e.g. struts action, browser client, or any client capable of consuming XML over HTTP). 2) As a control framework for a Java client, allowing me to reuse presentation tier logic across multiple channels (e.g. I can re-use non-visual logic process flows in a struts based web app). I'm also thinking about working on an editor for composing activity flows, rather than having to hand edit XML files. I may even end up generating code so that the activities end up as compiled classes, rather than dynamically constructed from an external definition. I would be using Eclipse EMF for this part, so I guess this wouldn't end up in Jakarta, but I would probably make it available through some other means.

I'm using it for two purposes which are I think a little beyond the original scope: I've used workflow engines for several very different purposes ... document management, customer relationship management, and most recently, enterprise application integration. They are incredibly versatile. I'm not surprised you would find applications outside the original scope of this project. In fact, I would venture to guess that people who happen upon this project, taken as a group, have a broad spectrum of requirements. 1) As a lightweight RPC mechanism, to locate and run server activities from any arbitrary client (e.g. struts action, browser client, or any client capable of consuming XML over HTTP). I'd like to hear more about this. 2) As a control framework for a Java client, allowing me to reuse presentation tier logic across multiple channels (e.g. I can re-use non-visual logic process flows in a struts based web app). Are you supplementing Struts here, or are you supplanting some of Struts traditional responsibilities? I'm also thinking about working on an editor for composing activity flows, rather than having to hand edit XML files. Awesome. This is always a plus. With a good XSD, even XML files are okay to hand-edit for a lot of people. But, I usually model a workflow process with a state machine diagram, anyway, so it would be nice to automate the XML generation part. I may even end up generating code so that the activities end up as compiled classes, rather than dynamically constructed from an external definition. I would still keep the ability to process the external XML definition, though, instead of replacing it altogether. Are you looking for performance gains, here? I would be using Eclipse EMF for this part, so I guess this wouldn't end up in Jakarta, but I would probably make it available through some other means. Haven't looked at EMF. A GUI process modeler implemented as an Eclipse plugin is interesting. Mike Colbert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I've been going through the archives, reading comments and suggestions. Would like to start looking into the possibilities of a more powerful process modeling/scripting mechanism. Something that can express more complex behavior, e.g. conditional transitions, composite activities, error handling, data-passing, etc. Mike Colbert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
