How to use Native with my own Java classes? [message #499710]

I have a short EVL file that looks something like:

...
var frame := new Native('javax.swing.JFrame');
...
var v := new Native('my.MyValidator');
...

The first statement works fine, but the second throws an error:

Type 'my.MyValidator' not found

The EVL file and the my.MyValidator class reside in the same project, and I run the EVL file using the EVL Validation run-configuration.

Any ideas why I cannot use Native('my.MyValidator') ?

Thanks !

Hi,

To use a Java class from Epsilon, it needs to either be in the classpath
or to be declared using the org.eclipse.epsilon.common.dt.tool extension
point. You can have a look at these two projects in the SVN for examples:

(tool implementations)
http://dev.eclipse.org/svnroot/modeling/org.eclipse.gmt.epsi lon/trunk/plugins/org.eclipse.epsilon.eol.tools/

(tool declarations)
http://dev.eclipse.org/svnroot/modeling/org.eclipse.gmt.epsi lon/trunk/plugins/org.eclipse.epsilon.eol.dt.tools/

Cheers,
Dimitris

Hi again,

I've just added a more detailed article on this:
