Hi
I want to work by ETL (epsilon transformation language). for primitive learning, i studied http://www.eclipse.org/epsilon and ran Tree2Graph project without any problem:) but for creating new ETL project what do i do? for example, let's suppose i want to create Tree2Graph transformation. I create two projects that one of them is project that contains two meta-models:tree.emf and graph.emf. second project must be contains Tree2Graph.etl, Tree2Graph.launch,.xml.launch, .xml.luanch and tree.model files. I create second project with Tree2Graph.etl, Tree2Graph.launch,and tree.model files but i don't know how i create launch.xml and .xml.luanch files? do you know any website or ebook that i study and learn how i create one epsilon project for ETL?
Thanks

Hi,

[1] provides instructions for creating .model files. Regarding .xml.launch files these are stored launch configurations (please see the Epsilon Launch Configurations section of [2] for details). Finally, .xml files are ANT workflow [3] scripts. I hope this helps.

Cheers,
Dimitris

Dear Dimitris, thanks a lot from your answer. I read [1] and this was so useful. about .xml and .xml.launch I read [2],[3] and I known these files. but my question is: do i must create these files manual or these file create automatically with Epsilon Launch Configurations? i do [2] step by step but i just could create .launch file!
is this possible help me for creating this file?

Hi,

I meant to write ".launch" instead of ".xml.launch" in my previous message - apologies for any confusion caused. The ".xml.launched" file is produced by storing the ANT launch configuration for the "launch.xml" workflow.

Hi, ok, Thanks alot.

but does this mean that I must create ".xml" file and then create ANT with below steps to creating of ".xml.launch" ?

1) Click External Tools Configuration... from the External Tools dropdown.
2) Select the ANT build for this build script.
3) Click the JRE tab.
4) Select the option that reads: "Run in the same JRE as the workspace."
5) Click Apply.
6) Click Run.

if i understood correctly, how i create ".xml" file?

Hi,

To create the ".xml.launch" file, after step 3) you need to select the "Common" tab of the launch configuration dialog, select "Shared file" under "Save as", and then select a folder where the persisted launch configuration should be saved.

Hi,

You can create XML files via the File->New->File menu.
