Hi all,

I was wondering if it is possible to run an ETL transformation from EWL. Here I see two possibilities: either to call the java code for running the ETL script, or that there is some built in way of calling an etl script from EWL?

Thanks in advance!

Hi,

There's no built-in facility for calling ETL from EWL so I'd suggest writing a small Java tool [1] that parses and runs an ETL module, and calling it from your EWL script. If you'd like your transformation to use a model already loaded in a (GMF/tree/xtext) editor, InMemoryEmfModel [2] may be of use.

Cheers,
Dimitris
