Native usage [message #1855229]

Hi folks,
I've been using Native constructs to load external Java libraries, but I'm struggling to load and use EqualityHelper.
I need to invoke the equals method, but even if I'm able to load EcoreUtil correctly via epsilon interface:
var emfTool : new Native("org.eclipse.epsilon.emc.emf.tools.EmfTool");
var ecoreutil = emfTool.ecoreUtil;

I can't do it the same for EqualityHelper which is a static class...do you have any suggestions?

Hi Ludo,

To be able to instantiate a Java class as a Native type in EOL, the class needs to be registered using the org.eclipse.epsilon.common.dt.tool extension point in the containing plug-in's plugin.xml, as is the case with EmfTool (see https://git.eclipse.org/c/epsilon/org.eclipse.epsilon.git/tree/plugins/org.eclipse.epsilon.emc.emf.dt/plugin.xml#n48). Does this help?

Thanks,
Dimitris

Maybe I'm missing something.
Here s my plugin.xml
<plugin>
<extension
point="org.eclipse.epsilon.common.dt.tool">
<tool
class="org.eclipse.emf.ecore.util.EcoreUtil.EqualityHelper"
defaultName="equalityhelper">
</tool>
</extension>
</plugin>
and in ETL:
var equalityhelper = new Native("org.eclipse.emf.ecore.util.EcoreUtil.EqualityHelper");
but still:
Type 'org.eclipse.emf.ecore.util.EcoreUtil.EqualityHelper' not found
