Hi Matt;
Actually I am going to do something like below. The data I'm getting
this from is a seperate DB table than the ones I have generated using
appfuse (I have created my own ETL process to build it). Is this the
hard way to do it? I am still learning hibernate and spring so I am
not totally comfortable with the framework.
Thanks,
Luke
public ModelAndView onSubmit(HttpServletRequest request,
HttpServletResponse response, Object command,
BindException errors)
throws Exception {
if (log.isDebugEnabled()) {
log.debug("entering 'onSubmit' method...");
}
Patient patient = (Patient) command;
boolean isNew = (patient.getPatientId() == null);
Locale locale = request.getLocale();
if (request.getParameter("delete") != null) {
patientManager.removePatient(patient.getPatientId().toString());
saveMessage(request, getText("patient.deleted", locale));
} else {
String countryId = request.getParameter("countryId");
String doctorId = request.getParameter("doctorId");
PatientData p_data = new PatientData(countryId);
patient.setPatientTag(p_data.getTag());
patient.setTreatmentarm(p_data.getTreatmentArm());
patient.setDoctorId(new Long(doctorId));//this is going to
come from the request
patientManager.savePatient(patient);
String key = (isNew) ? "patient.added" : "patient.updated";
saveMessage(request, getText(key, locale));
if (!isNew) {
return new ModelAndView("redirect:editPatient.html",
"patientId", patient.getPatientId());
}
}
return new ModelAndView(getSuccessView());
}
public class PatientData {
private String tag;
private int treatmentArm;
PatientData(String countryId) {
//connect to the DB to get the next available values for the
countryId
this.tag = "value from DB";
this.treatmentArm = 0;//value from the DB
//update the assignment date so these values will not be
selected again
}
/**
* @return the tag
*/
public String getTag() {
return tag;
}
/**
* @param tag the tag to set
*/
public void setTag(String tag) {
this.tag = tag;
}
/**
* @return the treatmentArm
*/
public int getTreatmentArm() {
return treatmentArm;
}
/**
* @param treatmentArm the treatmentArm to set
*/
public void setTreatmentArm(int treatmentArm) {
this.treatmentArm = treatmentArm;
}

The method of how data is retrieved from the database should already
be setup for you - with Managers, DAOs, etc. Showing us pseudo code
for what you're trying to do with make it much easier to help.
