Hi

I have generated an Xtext grammar from an existing Ecore Model. I am able to create an instance of the grammar. The problem comes when I chose the option "Open With -> sample reflective ecore model editor". I tried writing a code to create an EMF editor from Xtext editor, it still had the exact error which is:

org.eclipse.emf.ecore.xmi.XMIException: org.xml.sax.SAXParseExceptionPublicID: lineNumber =1; columnNumber = 1; Content is not allowed in prolog."

Please help. Thanks in Advance.

Regards
Puneet

Hi Puneet,

please make sure that your plugin.xml files contain all the necessary
registrations, e.g. for the file extension that you use, you have to
have a proper extension parser registration.

Best,
Sebastian

Hi Sebastian

Thanks for your response. I am able to fix the problem above. Smile It was a mistake, maybe on my own part. It was beacuse, the file extension variable in my Workflowgenerator was something else and the extension for editor of my xtext grammar was something different. So the XtextResourceSet.getResource() function threw the above exceptions. After changing the file-extension in workflow, it is working smoothly.

Thanks a lot.. Smile
Puneet

Hi Sebastian

I am still not able to get the "Sample Reflective Ecore model Editor " to work. Although I got my own piece of code to work and produce the EMF model editor. But now I want to open my xtext model with the option "Sample Reflective Ecore model Editor ", so that I can make changes through the generated editor. I also want to know how to create extension parser registration for my file extension, as you suggested above. I am quite new at this. Sad Please help. I am getting the following error.

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.xml.sax.SAXParseExceptionpublicId: platform:/resource/mnc.test/src/gmrt.mncspec; systemId: platform:/resource/mnc.test/src/gmrt.mncspec; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.

Regards
Puneet

Could you provide a reproducable example (a self contained one, e.g. the
complete projects)?

Best,
Sebastian
