Ângelo,
I added some debug output and I think I found the problem but have no solution yet...
Activator.getDefault().log("IEOSQLGeneratorFactory object class : " + o.getClass().getName()); for (Class anInterface : o.getClass().getInterfaces()) { Activator.getDefault().log("interface : " + anInterface.getName()); } Activator.getDefault().log("IEOSQLGeneratorFactory object class Loader : " + o.getClass().getClassLoader()) Activator.getDefault().log("IEOSQLGeneratorFactory class Loader : " + IEOSQLGeneratorFactory.class.getClassLoader());
The output: !MESSAGE IEOSQLGeneratorFactory object class : org.objectstyle.wolips.eomodeler.core.sql.EOFSQLGeneratorFactory !MESSAGE interface : org.objectstyle.wolips.eomodeler.core.sql.IEOSQLGeneratorFactory !MESSAGE IEOSQLGeneratorFactory object class Loader : org.eclipse.osgi.internal.loader.EquinoxClassLoader@289c2793[org.objectstyle.wolips.eomodeler.eclipse:4.4.20150506.01(id=1470)] !MESSAGE IEOSQLGeneratorFactory class Loader : org.eclipse.osgi.internal.loader.EquinoxClassLoader@2dcbf825[org.objectstyle.wolips.eomodeler.core:4.4.20150506.01(id=1469)]
So these are 2 different class objects from 2 class loader for the same class.
Anyone know how to fix this ?

In IEOSQLGeneratorFactory.java I made this
Object o = configurationElement.createExecutableExtension("class"); System.out.println("object class : " + o.getClass().getName()); IEOClassLoaderFactory classLoaderFactory = (IEOClassLoaderFactory) o;
And got this output
object class : org.objectstyle.wolips.eomodeler.eclipse.EclipseEOModelGroupFactory
The returned class is neither EOFSQLGeneratorFactory nor IEOSQLGeneratorFactory

I also get the same error. I modified a plugin.xml file that seemed incorrect and now I have this one:
java.lang.ClassCastException: org.objectstyle.wolips.eomodeler.core.sql.EOFSQLGeneratorFactory cannot be cast to org.objectstyle.wolips.eomodeler.core.sql.IEOSQLGeneratorFactory at org.objectstyle.wolips.eomodeler.core.sql.IEOSQLGeneratorFactory$Utility.sqlGeneratorFactory(IEOSQLGeneratorFactory.java:29) at org.objectstyle.wolips.eomodeler.actions.GenerateSQLDialog.generateSql(GenerateSQLDialog.java:297) at org.objectstyle.wolips.eomodeler.actions.GenerateSQLDialog$1.run(GenerateSQLDialog.java:279) at java.lang.Thread.run(Thread.java:745)
I do not understand how it is possible; EOFSQLGeneratorFactory implements IEOSQLGeneratorFactory !
public class EOFSQLGeneratorFactory implements IEOSQLGeneratorFactory { ... }
