Good day mdt.ocl,

My apologies in advance for posing the kind of question I always hate
answering myself, namely, one about the capabilities of some ancient
version of the product on which I myself work :-)

The aforementioned product runs on a target platform based on Indigo /
3.7.2 and EMF 2.7.2 (these versions beyond my control) and we're
currently using OCL 3.1.2 (for Ecore only, don't care about UML). With
the OCL 4.1.1 SDK installed in my IDE I was able to get declarative OCL
to generate interpretively executed Java code but even with the
documented workspace / project / genmodel settings was unable to get
'Generate Java code in XxxBodies classes' working. We're looking to
improve validation performance so the latter is of great interest.

From what I've been able to tell from poring over bundle manifests, I
ought to be able to get pure Java codegen by installing the
org.eclipse.ocl_3.4.2.v20140725-2242 feature (from the latest and
greatest mdt-ocl-runtime-5.0.2) in the target platform. Would you agree?

Thanks,

Adrian Price

Hi

See https://wiki.eclipse.org/OCL/FAQ#Does_Eclipse_OCL_work_with_J2SE_1.4.3F

The Luna release was tested on Juno.

I think that Xtext 2.3 is the limiting factor; there is compatibility
code to go from 2.3.1 to 2.3. Maybe earlier would work too, but Xtext
evolved quite signifucantly in its early releases. UML 4.0 is also a
lower bound.

If you are prepared to install Luna EMF,Xtext,UML,OCL you should be ok
on Indigo and possibly even Helios.

OCL to Java code generation has been mostly steadily improving so
anything less than the Luna SR is misguided.

The Mars milestones should be better but haven't been tested so there
may be a stupid manifest errors that prohibits it.

Regards

Ed Willink

Hi Ed,

Many thanks for the info and, as always, the swift response.

Cheers,

--A

P.S. Keep up the good work - I think it's terrific what you guys are
doing with OCL and QVT!

Hi

I just tried 5.1.0M2 on 3.8.2 with its Juno repo contributions. All
seems ok.

Regards
