(1) Is it possible to combine JET with OCL, means to do some OCL actions in a JET-template?
(2) Is it possible to retrieve UML profile information in a JET-template?

Thanks for answer,
Siegfried

Siegfried:

Out-of-the-box, JET includes not support for OCL. But, there is nothing preventing you from creating a custom tag or two (equivalent to c:get, c:iterate and c:if, for example) that use OCL instead of XPath. It has been done - unfortunately, the individual who did it was unable to contribute it back to the project Sad

As for accessing UML profiles with the XPath engine, this is possible. The Galileo release (M2T JET 1.0.0) includes uml2.stereotype function:

http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse .jet.doc/references/xpathFunctions/uml2.stereotypeFunction.h tml

It lets you test for and access a UML2 stereotype for any UML element. The function is roughly equivalent to calling this UML2 API:

http://help.eclipse.org/galileo/topic/org.eclipse.uml2.doc/r eferences/javadoc/org/eclipse/uml2/uml/Element.html#getStere otypeApplication(org.eclipse.uml2.uml.Stereotype)

Since the API returns an EObject, you can use XPath expressions to access its attributes. E.g.

uml2.stereotype(/Model,'Foo::Bar')/@someProperty

or

//Package[uml2.stereotype('Ultimate::Question')/@answer = 42]
