Example of running ETL trafo from java? [message #1383199]

Hello,

Are there any examples of running an ETL transformation from java? I have it running form an Ant script but want to run natively (per recommendation in this thread).

I found the following snippet (from here):

    URI outputModel = URI.createFileURI("C:/model-gen/model" + i + ".xmi");
    etlExecutor etlExecutor;
    etlExecutor = new etlExecutor("pathToetlSource");
    etlExecutor.addSourceModel("inputModel", inputModel,    URI.createURI("metamodelIn"));
    etlExecutor.addTargetModel("model" + i, outputModel,  URI.createURI("metamodelOut"));
    etlExecutor.execute();

However I can't seem to find the 'EtlExecutor' class (I presume it's a typo above & should be capitalised?). So any pointers would be appreciated; for example:

- I assume the respective input & output metamodels need to be registered before running the transformation?
- Does the execution take care of creating the target model file - or does it need to be created first?
- which packages/bundles need to be imported in plugin.xml?

Many thanks.

Hi Scott,

Please see [1] for an example demonstrating running ETL [2] from Java.

Cheers,

Hi Dimitris,

Thanks for the quick response - that's great. And apologies, I should have found them myself (need to practice my googling...!).
