my name is Martha and I try to create a portlet the simplest way. So, I choose jdeveloper
I follow the example "turn applications into portlets Vanessa Wang"
I have installed all the webcenter extensions, I open the file WeatherTaskFlowApplication.jws, right click and run and I have the message

#### Server Instance IntegratedWebLogicServer could not be started: Error starting Server Instance.

I have read the other threads, did not make any changes to enviromental variables or home directory, because I believe tha the server or the db has a problem.
I want to develop a simple portlet with java. And then consume it to Oracle Portal Do you have to advise me with the easiest way????

Thank you, very much in advance
