Re: [henshin-dev] Create GenModel problem: PUT failed with HTTP response code 403?
Hi Jerry,

actually you are not alone with that problem. In the past I solved this the following way: Despite of the error, usually the genmodel has been created anyhow. If you then trigger the code generation, further errors in the generated classes occur, which, however, can be resolved easily.

If you do not need a mapping model tailored to your certain case, you may want to try out our self-contained "trace model" (org.eclipse.emf.henshin.trace)! It consists of a class "Trace" with references "source" and "target" running to EObject, i.e., an object :Trace may refer to *any* EMF object. Trace is additionally equipped with an attribute "name:EString" which may contain further mapping-related information. In the case, that you plan to persist the mapping between source and target model, Traces may contain other Traces by reference "subTraces[0..*]: Trace" which allows to build an EMF conform containment hierarchy.

Best regards,
Stefan

Hi,

I came across a strange problem with HTTP code 403 while creating a genmodel from a ecore file. I know this isn't a Henshin problem but after solving this problem I'll go ahead to an exogenous transformation. So I'm really appreciated if someone here can help me with this.

Below are the steps I followed. I have also attached the needed files so you might like to regenerate the environment.
  1. I created two simplest ecore projects: exSource and exTarget.
  2. I created the corresponding genmodels within these projects and generated all the codes.
  3. I exported exSource and exTarget as jar files and put them into Eclipse plugin folder. Then I restarted Eclipse to load them.
  4. In order to make a "mapping model" as the ecore2genmodel example suggests, I created another ecore project: pivot.
  5. I opened pivot.ecore and "Loaded Resources" exSourceModel and exTargetModel (according to their URLs) from "Regestered Packages". Then I filled it with structure like below.

     6. Everything works fine until now. Then I tried to create a genmodel from this pivot.ecore like below. At the final step right after clicking "Finish" I received this error.

It's really strange for EMF to try PUTing. I mean even if it was trying to verify the URL mentioned in the ecore file, that URL (http://jerryhong.net/exSource) is reachable and doesn't deserve a 403 code.

I'm wondering if anyone has come across this problem before. Thank you.
