Question

tw.system.invokeREST can attached document, if ECM id is supplied as input. Does any one know invokeREST implementation jar/class?

I want to replicate the same functionality for email. However don't want to reinvent the wheel.

Answer 1

As I understand you want to use the invokeREST to attach/get document. This will be done from a javascript in a service flow the method to construct the request is detailed at this link

https://www.ibm.com/support/knowledgecenter/en/SSFTN5_8.5.7/com.ibm.wbpm.wle.editor.doc/topics/cdev_restapis_invoke_rest.html

you will need the operation name of the REST API, as far as I know There is no REST API to get the document only uploads. The Content Management Toolkit has services to get the document so you will not need to invoke REST API.

Please clarify the source of document local content store or ECM you are trying to retireve.
