Running a .class file without re-solving the model

I have a 3D model which takes a long time to solve. I need to export a lot of data sets from the model, so I want to to save the model as .java file and use this to edit export options instead of using the GUI. But when I compile the .java file and run the .class file, it resolves my model, which takes ages.

Is there a way to save my solution and modify the .java file so that it doesn't re-solve the model each time I run it?

Thanks,
Elli
