Atelier unable to load class Startup

Primary tabs


Just today updated Atelier to the latest Beta release.Getting the following error in Eclipse:

Plug-in com.intersys.eclipse.legacy.extension was unable to load class com.intersys.eclipse.legacy.extension.Startup.

Unable to open Atelier perspective.

Does anybody else get this issue, how to go back to previous version?

Can you delete the com.intersys.eclipse.legacy.extension*.jar plugin from the plugins folder and reboot Atelier to see if it helps?

Please note that the Atelier standalone is discontinued. We suggest you download Eclipse and install the Atelier plugin to simplify the upgrade processes. Please see this post ( for details.

I guess that discontinuing Atelier standalone is one way of dealing with the issue Thomas reported wink

Hi, I have never used the Standalone installation. From when we started using Atelier we have installed Eclipse with the Atelier installed as a plugin
