Hi!!!
I'm trying to create a query using EMF Query to get a List with all
classes from one specific package.
But I'm having one error in the Query execution.
One Part of the code:
------
OCL focl = org.eclipse.ocl.ecore.OCL.newInstance();
try {
fBooleanOCLCondition = new BooleanOCLCondition<EClassifier, EClass,
EObject>(focl.getEnvironment(),"self.oclIsTypeOf(EClass)",null);
} catch (ParserException e) {
e.printStackTrace();
}
fSelectQuery = new SELECT(new FROM(aPackage), new
WHERE(fBooleanOCLCondition));
------
The variable aPackage is from the EPackage type.
The Error msg:
-----
Exception in thread "main" java.lang.NoClassDefFoundError:

I would like to ask if some of you knows what it could be!
Thanks a lot in advance,

Hi, Ed, Lucas,
OCL and the LPG Java Run-time definitely work in a stand-alone
configuration, and the EMF Query code should, too, as it doesn't have
any extension points. I can't guarantee the latter, but it's worth a
try.
In any case, the dependency that Lucas is missing is the
net.sourceforge.lpgjavaruntime_1.1.0.qualifier.jar bundle. It's
included in the MDT OCL distribution.
HTH,
Christian

Lucas,
It just sounds like you have libraries missing. I.e., the ones needed
to parse the OCL expression. I'm not sure this stuff even works
stand-alone. Probably you need to run as an OSGi application...
