vennela,
I have a question for you with regards to your answer that it is not possible to connect to webservices directly thro workflow.(Please pardon me for my ignorance.)
When I was searching for information on the IBM website for the new features for workflow 3.4
i saw that
Support for Application Connectivity
XML
WebSphere MQ (35+ platforms)
J2EE
Web Services is available in workflow 3.4.
What does this mean then?
Thanks for your help! |

I am not sure what they mean by that.
I think they also mentioned web services are available in 3.3.2
There is a component called web client that runs under webshpere application server. This can be customized. Maybe there you can plug some sort of web services there.
I don't know what fall into the web services category ( SOAP, WSDL, UDDI, ? or what ), but the technical manuals do not mention anywhere any example or implementation procedure on using web services.

For MQ Workflow 3.4 there is a WebServices toolkit,
WA07: MQSeries Workflow - Web Services Process Management Toolkit
WSBI (WebSphere Business Integrator) server supports WebServices calls directly from workflow.

Dan:
I have not seen this support pac before and I am sorry if I have given any wrong information in my previous posts.
But, I have read the Description and Possible Uses parts on the Support Pac web page and I still doubt if there is a direct callable structure within workflow.
I will definitely try to play with it and see what the support pac can offer. But my gut feeling is that, we will have to rely on the XML interface of WMQ Workflow to do anything of this sort (like web services) and that boils down again to the basic workflow functionality and nothing more.
Thanks for pointing to the support pac. It is worth taking a look I guess.

I dont see why not if you are talking about an activity with in your model to be a service requester.
If you want WF to be at the service provider end, then I believe WA07 comes into the picture.

WA07: MQSeries Workflow - Web Services Process Management Toolkit is a year old and not on the current development path but it is a stepping off point
WA07 uses the XML/UPES interface to provide the services - there are many other ways of SOAP enabling a UPES interface - you can even do it as a SOAP-WMQI-MQWF implementation
The current IBM development path (from an outside observer) is WebServices Gateway connecting to WPC (Process Choreographer) - using WAS5 Enterprise version - which has a lot of neat functions and is very expensive.
There is another SOAP Workflow direction - BPEL4WS - do a google search
The issues with any SOAP implementation are that it is loosely coupled which means management, access, security and version control problems

BPEL (beepel) is the way to go.. ibm is seeing wsad5/was5 and bpel are the combination for future process mgt.

I know this post is quite dated, but I am wondering if anything has changed with regards to Web Services. I was reading PDF on Workflow version 3.5 and it looks like it's now possible to make a SOAP call to a Web Service from Workflow using version 3.5. This is the first I have ever heard of this feature.
Does anyone know if this statment is true or am I just reading this wrong?

WebSphere MQ Workflow supports
interaction with J2EEapplications using XML messages
and MQSeries Java programs (and XSLT, for example),
JMS publish-subscribe (for monitoring audit events), and
SOAP Web services. |
Here is a link to the PDF document out on IBM's web site. Look under the section labled: "J2EE application programs and user interfaces to business process workflows"

Dave:
Wouldn't this (a direct call to a Soap service) require some mechanism to specify the service address in the activity?
I know of no changes like this in Buildtime for 3.5.
My guess is that the statment is misleading. I certainly can read it the way you are reading it (in fact I would read it 100% the same). I am just not sure this is how the statement is meant to be interpreted.
Just my opinion.
Another thought came to me.... I don't have 3.5 installed and cant check this out... but maybe they rolled the support pack into the base product with 3.5.
