Hi, Zhang Xiaorui,

While the newsgroups are out of commission,
I can answer your questions on the dev mailing list.  When they return,
I'll post this thread to the newsgroup which, as Ed indicates, is the appropriate
forum for such questions.

Concerning (1)  The OCL plug-ins
have no user interface components; they only provide API and documentation
in the on-line help.  Up to and including OCL 1.1 M4, it will work
with EMF 2.2 and Eclipse 3.2.  M5 and later will only work with EMF
2.3 and Eclipse 3.3.

I don't know of any tutorial that defines
an EConstraint type.  Do you perhaps mean the Eclipse Corner article
"Implementing Model Integrity in EMF with EMFT OCL"?  This
is only an article illustrating how the OCL component could be leveraged
in an EMF-based application; the code generation that it illustrates is
not provided out-of-the-box by the OCL component.

(2)  The Interactive OCL Console
can load OCL expressions from XMI, although support for serialization before
M5 is very weak, and is much improved in the latest M5 integration build.
 The principal purpose of the console is to accept OCL query expressions
in the bottom panel (just type them in) and show the results in the top
panel.  See the example guide in the OCL on-line help.

(3)  This is the purpose of the
Eclipse Corner article, the Interactive OCL Console example shipped with
the OCL SDK, and the tutorial in the on-line help.  If that isn't
enough to get you started, then I and others will be happy to answer your
specific questions on the newsgroup.  Regarding accessing the JAR
files, you did that when you installed the OCL plug-ins.  To access
the API from your plug-in, just be sure to import the packages that you
need via Import-Package or Require-Bundle headers in your bundle manifest.

HTH,

Christian

OCL is now part of the MDT project which has its own mailing list, mdt-ocl.dev@xxxxxxxxxxx,
but it's best if you direct your user questions to the OCL newsgroup:  news://news.eclipse.org/eclipse.modeling.mdt.uml2.ocl
  

Note that all the Eclipse newsgroups appear to have been down since yesterday...

Subject	[emft-dev] Questions about the emft ocl plugin.

Hi, all 
I have been trying to use the emft ocl plugin in a metamodelling project,
but encountered some problems: 
  
1. Install: I installed the ocl plugin into my eclipse 3.3 ( with EMF 2.3).
But after that, I can't find anything about ocl in any menu and right-click
pop-up menu. Then I checked the configuration management, and found that
" object constraint language 2.0" installed without any problems.
So how should it look like after   installing the ocl plugin? And
when I tried to edit the ecore model, and right clicked one of the Eclass,
there was no "Econstraint" as it is showed in the tutorial. So
have I installed it properly? And can the plugin work on eclipse 3.2? 
  
2. About the examples: I downloaded the ocl examples and
imported it in the eclipse, then ran it with another instance of Eclipse.
After creating the model in the other Eclipse, I found the "ocl interpreter"
while right clicking the object in the model. But the "interactive
ocl" needs to load an "xmi" file of ocl _expression_. So I
am confused by this step, can you give me any instructions? 
  
3. About the project I am working with: The project is trying to make a
SDL+ plugin for Eclipse. In the package I am working with, there are an
ecore model, *. sdl_plus model and an ocl file. And I am trying to make
use of ocl plugin to check if the two models corresponding to the ocl file.
Would you please give me some suggestions about how to use ocl plugin in
my project? Can you provide any methods to get access to the Jar files
of ocl plugin? 
  
I am looking forward to your reply. 
  
Thank you in advance! 
  
Regards! 
Sincerely yours,
