Hi,
I followed the Acceleo tutorial below to write my first project in Acceleo
https://wiki.eclipse.org/Acceleo/Getting_Started
I followed all the instructions and i did all necessary modifications in the manifeste and generate.java files.

I tried first to generate an simple file containing the name of my model and a simple text " I hope it works". The file is generated correctly.

It seems that every think is OK but i still have an error message , i can't understand why i have such error.

Hoping to find an explanation for this error before i start writting my templates.

Thanks in advance
Best regards

Acceleo's support page for the best forum to use for asking questions about it:

https://www.eclipse.org/acceleo/support.html

Your screen captures show logged errors, but it's not clear that those actually came from generating with Acceleo or from something else you did at some historical point in time. I'm sure anyone following up on your question will ask the see the full stack trace recorded with that error log entry; you can capture that by double clicking on the log entry and using the upper right tool button to copy the details to the system clipboard.
