Hi,
The java library from the Pro version should be able to access the WsdlTestStepRegistry as it can also access open source libraries.
The code I provided will not work for open source SoapUI.
For this question,
As I suppose, this feature is used if light-version users want to create steps which are displayed in SoapUI afterwards, but can not be used, because of the missing pro-licence. Am I right?
Nope this script will not create a dataSource testStep in opensource it will throw error. The WsdlTestStepRegistry is accessible for Pro, I would suggest you to try the code.
Thanks,
Jeshtha
