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.
Reference Links: http://www.innovation.ch/java/HTTPClient/emulating_forms.html
http://www.nabble.com/AW:-Form-submit---validate---display-error-message---cycle--%3E-what--is-the-recommended-way-to-implement-this--t4739848.html 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.
