Comment #2 on issue 482 by cy.delaunay: Use JNIPort to connect to VerveineJ http://code.google.com/p/moose-technology/issues/detail?id=482 you should now use that: Gofer new url: 'www.squeaksource.com/DelaunayTmpStuffs'; package: 'JNIPort-Initialization'; load. Gofer new url: 'www.squeaksource.com/DelaunayTmpStuffs'; package: 'JNIPortExample'; load. The initialization part still has to be fixed, sometimes it works, sometimes not.
