Unable to create a component with TinyMCE in WPC 2.0 NW 7.3

Hello,

I follow the guide to implement TinyMCE in Web page composer 2.0 in Portal 7.3(http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0983d9b-327e-2e10-1aac-b33328877548?QuickLink=index&overridelayout=true&52596169587931), but i am unable to create a Paragraph with TinyMCE because i have the exception "Could not create content; contact your portal administrator for assistance". In the server log it says that it is unable to find the class com.sample.km.wpc.editor.TinyMCEComponent. do you have any advice?

Here is the logs:

Errror loading component class, com.sample.km.wpc.editor.TinyMCEComponent, class not found com.sap.nw.pcc.km.service.editor.EditorException: Errror loading component class, com.sample.km.wpc.editor.TinyMCEComponent, class not found
