Re: Shark: Why should I use shark/xpdml

["Sasa Bojanic" <sasaboy@xxxxxxxxxxxxx>]

Hi,

1. Using shark you can overcame various business problems. For every
particular business process, you can write an XPDL process that represent it
(of course there are some rules when creating xpdl presentations of real
business process, you have to read the XPDL specification, and learn more
about Workflows).
2. The advantage of using Shark is that you do not need to write new
servlet/jsp when you need to model new Business process - you just write an
XPDL file describing this process (look at JaWE, our graphical XPDL editor
used in Shark admin application at http://jawe.enhydra.org). Also, I don't
know if you can distribute the workitems using servlet/jsp technology. Shark
server distributes the work to the proper users that are logged on server.
When some user finishes its work, he sets some process variables that
determines the further process flow. The Shark server based on these
variables determines who are the next users that should get the work. Also,
you can run many processes in Shark server concurrently, i.e. you can run 5
instances of the main business_example process (Each instance for the new
order), and at the same time you can instantiate some of processes from
test.xpdl.
3. Currently the Shark does not have much documentation (all Shark documents
you can find under doc directory - I think that sharkclientinfo.txt is the
most useful), and you can go to the http://www.wfmc.org to read more about
WfMC workflow specifications, particularly the documents
http://www.wfmc.org/standards/docs/tc003v11.pdf - Workflow Referenc Model
(it gives the big picture of WfMC workflow specifications and workflow
technology at all),
http://www.wfmc.org/standards/docs/TC-1025_10_xpdl_102502.pdf - XPDL
specification (it defines how the xpdls should be created, the JaWE
implements this specification),
http://www.wfmc.org/standards/docs/if2v20.pdf - the client API (the
description of what an engine should implement),
http://www.omg.org/docs/formal/00-05-02.pdf  - OMG specification for engine
implementation in Object Oriented languages.
4. Maybe the business example is to complicated, but it shows the pretty
real example of some business process flow. If you have some real business
process, you can describe it, and we could try to implement it in XPDL, and
then let you execute in Shark server.

Hope I helped a little!

Regards,
Sasa.
