[Building Sakai] Sakai 2.8 Startup Problem with a new tool

[Mustansar Mehmood]

Hi,
    I am trying to write a small new tool using sakai app 
builder(wicket). While trying to start sakai with that tool I get this 
error. Can anyone please tell me what is going on and how to get past this.
Regards,
Mustansar
