An org.eclipse.emf.validation.examples.ocl example plug-in howto [message #64066] Mon, 03 November 2008 12:38 Go to next message
Eclipse UserFriend
Hi,
I know a lot of people, including myself, have had a lot of trouble
getting the very nice org.eclipse.emf.validation.examples.ocl example
plugin to work [see
http://wiki.eclipse.org/EMF-QTV_1.1_New_and_Noteworthy#New_V alidation_Constraint_Provider_Example]
with their own model/constraints. To this end I have written a quick howto
for new users. If I have time, and if people are interested, I can convert
this into an Eclipse Corner article. Any errors you find please report
them.

In case you don't know the purpose of the plugin was written to allow OCL
constraints to be defined in a text file. These constraints are then
applied to a model and can be validated using the Eclipse Validation
Framework.

So now the howto....

1. Install Eclipse Modeling Environment from
http://www.eclipse.org/downloads/packages/eclipse-modeling-t ools-includes-incubating-components/ganymeder

2. Create a new empty EMF project
File->New Project->Empty EMF Project
Project name: org.mycompany.product

3. Import an existing EMF model into the new project
Select the "model" folder
Right click and select Import->File System
In this example the model imported is myModel.ecore

4. Create the .genmodel for the EMF model so we can autogenerate the GEF
based model editor
New->Other->EMF Model
Name: Product.genmodel
Select Ecore model importer
Select the myModel.ecore model

5. Open the new Product.genmodel
Select the root object and righ click
Select "Generate All"

This will create a GEF based editor off the myModel.ecore model

6. Bring the OCL example code into your project
File->New->Example->OCL Example
File->New->Example->General Validation Example
File->New->Example->Validation Adapter Example

7. Delete the following projects as we do not want to use the generated
"Library" example settings
org.eclipse.emf.examples.library
org.eclipse.emf.examples.library.edit
org.eclipse.emf.examples.library.editor
src folder from under org.eclipse.emf.validation.examples.ocl
Library.ocl file from constraints folder in
org.eclipse.emf.validation.examples.ocl

8. Place our OCL constraints file in the OCL folder in
org.eclipse.emf.validation.examples.ocl
Select the "constraints" folder
Right click and select Import->File System
In this example the constraints imported are Product_constraints.ocl

9. Open plugin.xml in org.eclipse.emf.validation.examples.ocl
Change the last constraintProvider meta-data to match your models
namespace and OCL file

<constraintProvider
class=" org.eclipse.emf.validation.examples.ocl.OCLConstraintProvide r "
category="Constraints from an OCL Document">
<package
namespaceUri=" http:///org/eclipse/emf/examples/library/extlibrary.ecore/1. 0.0"/>
<ocl path="constraints/Product_constraints.ocl"/>
</constraintProvider>

10. Edit plugin.xml in org.eclipse.emf.validation.examples.ocl and change
the namespaceUri as noted below

*Delete
http:///org/eclipse/emf/examples/library/extlibrary.ecore/1. 0.0
*Insert http://www.mycompany/product

11. Fix dependencies in org.eclipse.emf.validation.examples.general
*Remove the following
org.eclipse.emf.examples.library
org.eclipse.emf.examples.library.edit
org.eclipse.emf.examples.library.editor

*Insert the following
myProduct
myProduct.editor
myProduct.edit
myProduct.tests

12. Edit plugin.properties in org.eclipse.emf.validation.examples.general
*Remove the following
EXTLibraryConstraintsCategory=EXT Library Constraints

NonEmptyNameConstraint=Non-Empty Names
NonEmptyNameConstraint.description=All items in an EXT library model
should have some unique identifier or name.

# 0 - An EClass(metaclass) name for the element that was found to have
no unique identifier.
NonEmptyNameConstraint.message=A {0} has been found to have no unique
identifier (name or title).

*Insert the following
ProductConstraintsCategory=Product Constraints

13. Edit plugin.xml in org.eclipse.emf.validation.examples.general
*Replace the first <extension/> with the following

22. Create a new Run Configuration so we can see the GEF editor for our
myModel.ecore
Run->Run->Run as Eclipse Application

This operation will result in a new Eclipse workspace session starting.
This new workspace will have the GEF based editor and OCL example plugins
built into it.

23. In the new workspace do the following.
Create a new empty EMF project
File->New Project->Empty EMF Project
Project name: myProduct

This will create a project to hold our instance model

24. In the new workspace do the following.
File->New->Example EMF Model Creation Wizards
Select Product Model
File name: my.Product

25. Create a model instance using the GEF editor

26. Validate the using the context menu (right click a model
element->Validation->Validate Elements... or simply right click a model
element->Validate)

27. Be impressed :)

Hi Ronan,

This is great! I think that this is really needed for new users getting to
grips with using OCL in EMF/UML2 projects. I would really like to see this
on the wiki or somewhere.

My $0.02 anyway,
Mark

Hi, Ronan,

(copying the EMF newsgroup which is home to this component)

I second Mark's comment: this is exactly the kind of contribution that
we are thrilled to see in the EMF Wiki. In fact, I think this would be
the first recipe for the validation component. Feel free to add it by
following the "Recipes" link, here:

http://wiki.eclipse.org/EMF/Validation#Documentation

As you probably know, the Wikipedia technology makes formatting a recipe
like yours a snap.

Thanks!

Christian

Hi all,
I have put up the recipe in the EMF Validation Framework documentation.

Thanks, Ronan, for the contribution!

I hope you don't mind, but I took a moment to tweak the formatting a bit
for some text that ran together in and to fix a few typos.

Hi,

I would like to thank you for this Recipe.
I tried it and i have few questions because I did not manage to make it
works. Maybe because I made some confusions.

I followed all the steps but none of the constraints described in my ocl
files are found. Do I need to do something else than fill the constraint
file and following all the indications of the recipe ? ?

And to be sure about a basic thing : When all the steps are done (my emf
project + 3 projects about validation are on the Package Explorer), from
which projet should I launch the program ?

I tried to import the OCL Exemple with the Library Model add other
constraints, and did not succeed. I thing i don't get an important point.


Thank you.

Florine
