Papyrus Java Code Generation [message #1777756]

Hi all,

for the papyrus java code generation I've followed :
(from youtube but it was not possible to paste the link: You can only use links to eclipse.org sites while you have fewer than 1 message.) watch?v=AXPDvAjv_NY
(idem) watch?v=mBzNww_3qtM]
and finally https://wiki.eclipse.org/java_code_generation

but in any case I'm unable to see the code. I'm on eclispe neon.3, with the latest version plugins from the tutorials (no other explicitly installed) and even if the java project is created, there is no source code. Do you have any advice what might be missing in the configuration? Thank you!

Hi,

could you please have a look at the "Error Log" and tell us, if there are any exceptions? Can you also tell us, which version of Papyrus and software designer you use?

When you say, that "even if the java project is created ...", does it mean that the project gets created, but you don't see generated source code files inside?

Hi Ansgar,

The plug-ins are in the attached file. I've Papyrus UML 2.0.3 and I use Papyrus Java Code generation for Papyrus 1.0.5.

If you have any other questions, please write. Thanks a lot!

P.S. And yes, it means that Java project file with Java library was created but src folder was empty.

That's the log:

Hi,

Can you try installing Xtend 2.12?

Please note that version 1.0.5 targets the oxygen version of Papyrus, , but it's possible to install it on neon. This is is a bug, since for instance the example install from Papyrus 3.x is required.
So, can you please either try to upgrade to oxygen or install version 1.0.4 of designer. You can do the latter by adding a "/neon" to the designer update site, i.e. use http://download.eclipse.org/modeling/mdt/papyrus/components/designer/neon

Thanks a lot Ansgar! After upgrading to Oxygen it worked.
I have one more Papyrus question not related to the head topic. I try to play a bit with MDA paradigm and I'm looking for some open-source projects or plug-ins that would help me to generate at once Java code and Hibernate/Spring interface for DB communication. Can Papyrus support both? If yes, which plug-in to use (after some google research I still haven't found a satisfying answer). Otherwise, do you know any tool which supports both? Thanks once again for your help.

There is currently no support for generating Hibernate/Spring in Papyrus SW designer - unless you volunteer doing it, it is extensible ;-). I'm not aware of a tool supporting this, but haven't really done an in-depth search.

Hi Jan,

to experiment with MDA I would rather suggest building your own model to text transformer using Obeo Eclipse Acceleo (https://www.eclipse.org/acceleo/). While being not as powerful as XPand/XTend Obeo Eclipse Acceleo as an OMG M2T (http://www.omg.org/spec/MOFM2T/About-MOFM2T/) processor is IMHO easier to learn. If you experience serious limitations, you can either extend the Papyrus Java code generator or build your own custom generators with XPand/Xtext. Acceleo scripts tend to require more compute time to execute than XPand/Xtend generators. If the generator performance becomes an serious issue, then you can switch and reuse the transformation rules. In this case Acceleo has done a good job as a RAD (Rapid Application Development) tool ;-)

Compuware OptimalJ was a MDA tool that also generated OR-Mapper artifacts. But this tools was discontinued in 2008.

Thanks a lot for your help Ansgar and Carsten!
Sorry for the delay in answering but it seems I haven't received any notification or I've missed it.
I'll try to play a bit more with the technologies.
Happy New Year 2018 :)
