Since the last update, I have impletmented POPUNDER.

The next move is to simulate HTML form submission via Java. The challenge here is how to obtain the session from the web site after I first submit username and password. Once this passes, there will be no technical problem.

One of the key point for the project is to automate all processes.

Pondering your (both) input, I like very much your idea of an
encapsulated object holding all data which is either captured from the
submitted form data or - if no form data have been posted - retrieved
from the model data (in my case, via Torque from the database).

So, the base class of such a form data storage would something like:

public abstract class FormData {

  /** populate with data from the HTTP request (submitted data) */
  public abstract void captureRequestParameters(RunData data);

  /** retrieve data from the business model */
  public abstract void retrieve();

  /** persists data into the business model */
  public abstract void save();

  /**
   * validate data, typically after capturing data from HTTP request
   *
   * @return flag: true ... data ok; false ... validation error
   */
  public abstract boolean isValid();

  /** one-in-all method */
  public void doSubmitAction(RunData data) {

    this.captureRequestParameters(data);
    if (this.isValid()) {
      this.save();
    }
  }
}

For each editable HTML form I would derive a concrete class from
FormData holding the specific form data needed.

I think I got the basic points, thank you both for your detailed
responses.
