Generete Porlets Form


hello friends, I created a portlet form edit in jde 9.2. After this I tried to continue with the generation of it but I could not get results. I have also researched about egenerator and read the oracle documentation but I could not go ahead. When I run it locally, it says "no entry point". Do I need any other tool? I need to associate it with other forms ?.
Thank you very much, greetings.
