Hi,

In a genmodel file, I have tried to call dynamic templates files that
are stored into my current workspace: it works.
After that, I have tried to call the same dynamic templates files that
are stored into my plugin installation: it does not work.

Is there a workaround to call dynamic templates that are stored into
plugins ?

Best regards,
Cyril.

Cyril,

If you use platform:/plugin/<plugin-ID> in the template path it should
end up in this code path in JETEmitter to look for the compiled
templates in the runtime environment

else if (templateURI.isPlatformPlugin())
{
final Bundle bundle =
Platform.getBundle(templateURI.segment(1));
if (bundle != null)
{
// Define a class loader that will look up the class in
the bundle,
// and if it doesn't find it there, will look in the parent.
//
theClassLoader =
new URLClassLoader(new URL [0], jetEmitter.classLoader)
{
@Override
public Class<?> loadClass(String className) throws
ClassNotFoundException
{
try
{
return bundle.loadClass(className);
}
catch (ClassNotFoundException classNotFoundException)
{
return super.loadClass(className);
}
}
};
}
}

Hi Ed,

Thanks to your reply, for further reasons I have my own "generator"
class, so I have added the missing plugin id like that:
CodeGenUtil.EclipseUtil.addClasspathEntries(classpathEntries , xyz, xyz)
and now it works in deployed mode.

Regards,
Cyril.
