I would like to find the data of all the users and sum of their scores on particular questions and find the highest rank
Now I can walk through the data users data but not through the questions node.
How do read all the data
This is how I have created my POJO :
private String id;
private String name;
private String contact;
private String email;
private String password;
private int score;
private String dob;
private String profession;
private String random;
private String status;
private String fbId;
private UserPuzzleDetails userPuzzleDetails;
public User() {

this.contact = contact;
this.email = email;
this.password = password;
this.score = score;
this.dob = dob;
this.profession = profession;

this.status = status;
this.fbId = facebookid;
this.userPuzzleDetails = userPuzzleDetails1;
}
public User(String id, String name, String contact, String email, String password, int score,
String dob, String profession, String random, String status, String facebookid) {

public String getStatus() {
return status;
}
public String getFbId() {
return fbId;
}
public void setFbId(String fbId) {

Now I have used this function to retrieve the data but it is not logging.
How should I go by this data iterate through it.
private void getAllRank() {
final DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference().child("users");
final Query query = databaseReference.orderByChild("score").limitToLast(10);
query.addValueEventListener(new ValueEventListener() {

userlist.add(new User(score.getId(), score.getName(), score.getContact(), score.getEmail(),
score.getPassword(), score.getScore(), score.getProfession(), score.getDob(), score.getRandom(), score.getStatus(), score.getFbId(),score.getUserPuzzleDetails()));
Log.e(TAG, "onDataChange: "+userlist );
}
}
#Override

session.beginTransaction();
session.save(appointment1);
session.getTransaction().commit();
session.close();
}catch(Exception ex){
ex.printStackTrace();
}
return appointment;
}
}
Is there any way that when i save the appointment object the new objects of patient and doctor not save to the database.
I shall be thankful :)
I think your relationship type should not be OneToOne from neither the doctor or the patient, because one doctor can have many appointments and one patient can have many appointments. So it should be OneToMany from both sides, in which case a new doctor and a new patient won't be created for each new appointment if you supply the appointment with correct existing doctor and patient ID-s.
In the class AppointmentClass, change the cascade settings.
You can use cascade=CascadeType.NONE, This will make sure that the associated Patient and Doctor objects are not saved to database.
You can see all other values of CascadeType to find the right choice for you.
I pass couple of objects "Studentdetails" and String-"dept" to JSP.
Question-
How will I refer studentdetail.st.fname in my JSP file? ie; need to refer the firstname from the Student object.
I tried this and its failing -
<form:label path="s.studentdetail.st.fname" class="labels">First Name</form:label>
AND
<form:label path="studentdetail.st.fname" class="labels">First Name</form:label>

Working code:---
<h2>Student Information</h2>
<form:form method="POST" action="/SpringMVC/addStudent" modelAttribute="studentdetail">
<br><br>
<form:label path="st.fname" class="labels">First Name</form:label>
<form:input path="st.fname" class="textbox" />
<br><br>
studentdetail:${studentdetail.st.fname}
<br>
Department:${department}
<br><br>
</form>
Controller:-
#RequestMapping(value = "/student", method = RequestMethod.GET)
public ModelAndView student() {
Map<String, Object> model = new HashMap<String, Object>();
model.put("studentdetail", new Studentdetails());
model.put("department", "dept");
return new ModelAndView("student",model);
Try :
<form:label path="s['studentdetail'].st.fname" class="labels">First Name</form:label>
If you are using an array of Studentdetails then you have to use that array on your form declaration on the modelAndAttribute field, and then using a foreach to iterate everyone, and using the index.
<form:form
id=""
method="post"
action=""
modelAttribute="studentdetail">
<form:input type="text" id=""
path="studentdetail.st.fname"/>
</form:form>
First your construction of a ModelAndView is at least uncommon. You add an unnecessary level of indirection by putting in string model an only attribute s that contains the real model. In JSP you should have to use ${s["studentdetail"].st.fname} ... if you had initialized studentdetail.st ...
IMHO, you'd better change your method to :
public ModelAndView student() {
Map<String, Object> model = new HashMap<String, Object>();
Studentdetails studentdetail = new Studentdetails());
studentdetail = new Studentdetails());
studentdetail.setSt(new Student()); //put a Student in studentdetail
model.put("studentdetail", studentdetail);
model.put("department", "dept");
return new ModelAndView("student", model); // directly use model in ModelAndView
}
Then in the JSP, you simply use ${studentdetail.st.fname}
In a web-service i have the following function which retreives some infos of a doctor and his patient based on patient's phone:
public String findDoctorOfPatient(String phone) {
AnnotationConfiguration config = new AnnotationConfiguration();
config.configure("hibernate.cfg.xml");
SessionFactory factory = config.buildSessionFactory();
Session session = factory.openSession();
session.beginTransaction();
Criteria query = session.createCriteria(doctor.class);
query.createCriteria("patients", "p");
query.add(Restrictions.eq("p.phone", phone));
List<doctor> doctorList = (ArrayList<doctor>) query.list();
session.getTransaction().commit();
String answear = "";
for (doctor d : doctorList) {
answear = answear.concat("docPhone" + d.getPhone() + "docEmail"
+ d.getEmail() + "patDia"
+ d.getPatients().iterator().next().getDiastolic()
+ "patSys"
+ d.getPatients().iterator().next().getSystolic());
}
if (doctorList.isEmpty()) {
session.close();
factory.close();
return "No Doctor!";
} else {
session.close();
factory.close();
return answear;
}
}
The problem is when i have one patient is ok , but when i add second patient it gives me the details of last patient despite i have set to criteria tha firt's patient phone!
I have 2 tables:
1.doctor(id,username,password,phone,email)
2.patient(id,name,surname,phone,systolic,diastolic,doctorid(FK refers to doctor.id))
I have configured properly the hibernate.cfg.xml.
And i have set the class for doctor and patient:
#Entity
public class doctor {
#Id
private int id;
private String username;
private String password;
private String phone;
private String email;
#OneToMany(targetEntity = patient.class, cascade = CascadeType.ALL, mappedBy = "doctor")
#Cascade(value = org.hibernate.annotations.CascadeType.ALL)
private Collection<patient> patients = new ArrayList<patient>();
public Collection<patient> getPatients() {
return patients;
}
public void setPatients(Collection<patient> patients) {
this.patients = patients;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
#Entity
public class patient {
#Id
private int id;
private String name;
private String surname;
private String phone;
private int systolic;
private int diastolic;
#ManyToOne
private doctor doctor;
public doctor getDoctor() {
return doctor;
}
public void setDoctor(doctor doctor) {
this.doctor = doctor;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public int getSystolic() {
return systolic;
}
public void setSystolic(int systolic) {
this.systolic = systolic;
}
public int getDiastolic() {
return diastolic;
}
public void setDiastolic(int diastolic) {
this.diastolic = diastolic;
}
}
In this web-service the response is always the same (given the mobile number) .
It gives me always the patSys=130 and patDia=80 which are the second's patient info!.Something must be wrong in the webservice but to me all seems ok!
You need to create Criteria object on Patient and no need to obtain transaction here.
Criteria query = session.createCriteria(Patient.class)
.add(Restrictions.eq("phone", phone));
List<Patient> patList = (ArrayList<Patient>) query.list();
String result="";
if(!patList.isEmpty()) {
Patient patient=patList.get(0);
result="Doc Phone : " + patient.getDoctor().getPhone();
}
return result;

I want to display the data into h:panelGrid. Can you tell me how I can do this?
I want to create this editable table but with h:panelGrid. I suppose that it's possible to use h:panelGrid instead h:dataTable?
Best wishes
While it may be actually possible to hack something with h:panelGrid, you probably would have to fiddle with a lot of unnecessary code in your MBs, just for creating and binding components.
If you want a finer grained control for your HTML table, what you want to do is probably to use ui:repeat, something like this:
<table>
<ui:repeat var="elem" value="#{yourMB.yourDataList}">
<tr>
<td>#{elem.userid}</td>
<td>
<h:outputText value="#{elem.name}"
rendered="#{not elem.editable}" />
<h:inputText value="#{elem.name}" rendered="#{elem.editable}" />
</td>
<td>
<h:outputText value="#{elem.telephone}"
rendered="#{not elem.editable}" />
<h:inputText value="#{elem.telephone}"
rendered="#{elem.editable}" />
</td>
<td>
<h:commandLink value="Edit" rendered="#{not elem.editable}"
action="#{yourMB.editAction(elem)}" />
</td>
</tr>
</ui:repeat>
</table>
<h:commandButton value="Save Changes" action="#{yourMB.saveAction}" />
For this to work you should have a backing bean looking like this:
#ManagedBean
#ViewScoped
public class YourMB {
private List<Elem> dataList;
#PostConstruct
public void init() {
// initialize dataList here
}
public void editAction(Elem e) {
e.setEditable(true);
}
public void saveAction() {
// do your thing here to update in the database,
// and then reset the editable property for all items:
for (Elem e : dataList) {
