IBM Worklight - CWWKX0202E: The WebSphere Java Man

问题:

I'm using IBM Worklight 6.2.0.00-20140825-1637 for my mobile app project.

I got this error message when I try to start my worklight server. It happened after I updated my worklight 6.1 in my Eclipse. Please advice.

I already found the answer. Create a new eclipse environment then install back eclipse studio.
