    Hello,

    I have a set of common services that I want to expose as a web service and call from different workflows. I can publish a web service, but I am not clear on how to incorporate a web service into other projects and retain the data that is generated. If anyone has experience working with this I would appreciate any assistance.

    Thank You :-)

    A generated web service component is what you're looking for. Once you have a published web service, run through the Web Server Caller generator to make your component(s).

    Hello,

    That is the direction that I have tried, but I end up with the same error message each time.

    My method is to publish the webform to the server, take the URL that is used access the form and paste it into the URL space and add it. Any ideas what step I am missing?

    Thanks

    OK, it looks like you've published this WF as a form start and you're trying to access the composer.aspx page as your webservice based on the error message. What you want to do is publish the workflow as a webservice (Publishing tab - Workflow Type = Webservice), and try contacting the .asMx file that gets created as a result.
