Native java code Tools example [message #989552]

Dear all,

I want to instantiate an EData Type (org.eclipse.draw2d.geometry.Rectangle) that is defined in my ecore model. This cannot be done directly, so I believe I'm required to use an AbstractTool with corresponding extension point?

Therefore, I'm trying to invoke the example given here: http://www.eclipse.org/epsilon/doc/articles/call-java-from-epsilon

However, the SampleTool is not found for some reason.

I couldn't find the mentioned .launch script, so here is the stacktrace from my plugin:

Type 'org.eclipse.epsilon.examples.tools.SampleTool' not found (/DEV/myplugin.xml.to.cspm/epsilon/transform.etl@13:28)
	at org.eclipse.epsilon.eol.types.EolNativeType.<init>(EolNativeType.java:37)
	at org.eclipse.epsilon.eol.execute.TypeExecutor.execute(TypeExecutor.java:75)
	at org.eclipse.epsilon.eol.execute.ExecutorFactory.executeAST(ExecutorFactory.java:226)
	at org.eclipse.epsilon.eol.execute.NewExecutor.execute(NewExecutor.java:26)
	at org.eclipse.epsilon.eol.execute.ExecutorFactory.executeAST(ExecutorFactory.java:226)
	at org.eclipse.epsilon.eol.execute.AssignExecutor.execute(AssignExecutor.java:48)
...

The used ETL script (line 13 onwards):

var sampleTool = new Native("org.eclipse.epsilon.examples.tools.SampleTool");
sampleTool.name = "George";
sampleTool.sayHello().println();

My eclipse version is Indigo SR2 + Epsilon 1.0.0.

Best regards,
Robert

Hi Robert,

This article provides an example that demonstrates how to create a new Java tool; SampleTool is not a real tool included in the Epsilon distribution. As such, to use it you'll need to create it first by going through the steps of the article, launch a new Eclipse instance and use it from there.

Cheers,
Dimitris

Hi Dimitris,

Let me clearify this. I downloaded the example, imported the plugin project in Eclipse & ran a new Eclipse instance (from the first Eclipse instance). The plugin is 'found', since I checked this in the installation details (Help -> About Eclipse).
However, the SampleTool is not found in the script.

Best regards,
Robert

Hi Robert,

This seems to be working fine for me. Could you perhaps check if you can instantiate any of the other tools (see Window->Show view...->Tools for a complete list of available tools)?

Cheers,
Dimitris

Hmm, this is strange. The SampleTool and others (like JavaTool, MathTool, etc) are shown in this view.
However, the example ETL script (still) doesn't work for me.

Are you launching the .eol script through a launch configuration or through Java code?

I'm running it from Java code, to be specific with an EtlModule.

Note, for the rest, I can succesfully transform models using this ETL/java code.

Have you perhaps added the following line to your Java setup as advised in the article?

context.getNativeTypeDelegates().add(new ExtensionPointToolNativeTypeDelegate());

Cheers,
Dimitris

Thank you very much. This was indeed missing and all works fine now.

Best regards,
