Hi All,
I'm using Texo to generate JPA entities from eCore models. I need to add some extra annotations to the generated classes, so I use EAnnotation. But I don't figure out a way to generate the parameters for the annotations. Example below:

To add the annotation table, I use the value of the EAnnotation as follows:
@javax.persistence.Table

How can specify this in order to generate the code as follows:

@Table(name="Student")
public class Student{
}

The parameter should be the class name.

Thanks,
Sandeep Joseph

Hi Sandeep,
I guess you have seen this page:
https://wiki.eclipse.org/Texo/Direct_Java_Annotations

So setting something like this in the eannotation should work:
@javax.persistence.Table(name="Student")

For this specific annotation Texo will generate it for you, so you don't need to add it manually. You should only need to add a specific annotation if you want to override the Texo generated annotation.

Let me know if this helps (or not ofcourse).

Hello Martin,

Thanks for your response. I already tried successfully what you have suggested. My use case is a bit different. The value to the parameter 'name' should be dynamic. I want to get it from the ECore model, for example the class name («this.simpleClassName-»).

@javax.persistence.Table(name=<CLASS_NAME_FROM_MODEL>)

Is this possible?

Thanks,
Sandeep

Hey Sandeep,
It should work out of the box like that, Texo as a default creates unique entity names, but you can override this with an option on your dev project:
https://wiki.eclipse.org/Texo/ORM_JPA_Options

Can you try without a table annotation, what do you get then?

gr. Martin
