cannot fetch the exact dto returned from ejb to liferay controller

I am doing a liferay project which use ejb at back end. so my ejb method looks like this:-
#Override
public List<RmisPaymentDetailsDto> getEpaymentDetails(String ebpCode) {
Query q = entityManager.createQuery("select s from EpaymentBo s where s.ebpCode=:ebpcode")
.setParameter("ebpcode",ebpCode);
#SuppressWarnings("unchecked")
List<ProductBo> list = q.getResultList();
Iterator<ProductBo> i = list.iterator();
List<RmisPaymentDetailsDto> rList = new ArrayList<RmisPaymentDetailsDto>();
while(i.hasNext()){
EpaymentBo ep =(EpaymentBo) i.next();
RmisPaymentDetailsDto dto = new RmisPaymentDetailsDto();
dto.setAdvertisementcode(ep.getAdvertisementcode());
dto.setAmount(ep.getAmount());
dto.setStudentmasterid(ep.getStudentmasterid());
dto.setEbpgendate(ep.getEbp_gen_date());
dto.setEbpcode(ep.getEbpCode());
dto.setPaymentstatus(ep.getPaymentstatus());
dto.setCandidatenameinnepali(ep.getCandidatenameinnepali());
rList.add(dto);
}
return rList;
}
the above method successfully fetches data from database and sets it to my RmisPaymentDetailsDto.
like this:-
now i am calling same method from my liferay controlller.
PreExaminationRemote preRef = (PreExaminationRemote) jndiContext
.lookup("PreExamination/remote");
List<RmisPaymentDetailsDto> rDto = preRef.getEpaymentDetails(ebpCode);
I am wondering how my one property(candidatenameinnepali) is lost as i return same dto from my ejb.
My dto looks like this:-
public class RmisPaymentDetailsDto implements Serializable {
private static final long serialVersionUID = 1L;
private String advertisementcode;
private String ebpcode;
private String amount;
private String studentmasterid;
private Date ebpgendate;
private String paymentstatus;
private String candidatenameinnepali;
public String getCandidatenameinnepali() {
return candidatenameinnepali;
}
public void setCandidatenameinnepali(String candidatenameinnepali) {
this.candidatenameinnepali = candidatenameinnepali;
}
public String getAdvertisementcode() {
return advertisementcode;
}
public void setAdvertisementcode(String advertisementcode) {
this.advertisementcode = advertisementcode;
}
public String getEbpcode() {
return ebpcode;
}
public void setEbpcode(String ebpcode) {
this.ebpcode = ebpcode;
}
public String getAmount() {
return amount;
}
public void setAmount(String amount) {
this.amount = amount;
}
public String getStudentmasterid() {
return studentmasterid;
}
public void setStudentmasterid(String studentmasterid) {
this.studentmasterid = studentmasterid;
}
public Date getEbpgendate() {
return ebpgendate;
}
public void setEbpgendate(Date ebpgendate) {
this.ebpgendate = ebpgendate;
}
public String getPaymentstatus() {
return paymentstatus;
}
public void setPaymentstatus(String paymentstatus) {
this.paymentstatus = paymentstatus;
}
public static long getSerialversionuid() {
return serialVersionUID;
}
}

Exception being thrown by hibernate in specifit request orders

I am experiencing strange behavior. I am using hibernate. I have two tables.
#Entity
public class Nemocnica implements java.io.Serializable {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name="N_ID")
private BigDecimal NId;
#Column(name="adresa")

public Nemocnica() {
}
public Nemocnica( String adresa) {
this.NId = NId;
}
public Nemocnica(BigDecimal NId, String adresa) {
this.NId = NId;
this.adresa = adresa;
}
public Nemocnica(BigDecimal NId, String adresa, Set sanitkas) {
this.NId = NId;
this.adresa = adresa;
this.sanitkas = sanitkas;
}
public BigDecimal getNId() {
return this.NId;
}
public void setNId(BigDecimal NId) {
this.NId = NId;
}
public String getAdresa() {
return this.adresa;
}
public void setAdresa(String adresa) {
this.adresa = adresa;
}
public Set getSanitkas() {
return this.sanitkas;
}
public void setSanitkas(Set sanitkas) {
this.sanitkas = sanitkas;
}
}
and second
#Entity
public class Sanitka implements java.io.Serializable {
private BigDecimal sanitkaId;
private transient Nemocnica nemocnica;
private BigDecimal kapacita;
#ManyToOne
#JoinColumn(name="nemocnica_n_id")
private Set sanitaris = new HashSet(0);
public Sanitka() {
}
public Sanitka(BigDecimal sanitkaId, Nemocnica nemocnica, BigDecimal kapacita) {
this.sanitkaId = sanitkaId;
this.nemocnica = nemocnica;
this.kapacita = kapacita;
}
public Sanitka(BigDecimal sanitkaId, Nemocnica nemocnica, BigDecimal kapacita, Set sanitaris) {
this.sanitkaId = sanitkaId;
this.nemocnica = nemocnica;
this.kapacita = kapacita;
this.sanitaris = sanitaris;
}
public BigDecimal getSanitkaId() {
return this.sanitkaId;
}
public void setSanitkaId(BigDecimal sanitkaId) {
this.sanitkaId = sanitkaId;
}
#ManyToOne(cascade=CascadeType.ALL)
public Nemocnica getNemocnica() {
return this.nemocnica;
}
public void setNemocnica(Nemocnica nemocnica) {
this.nemocnica = nemocnica;
}
public BigDecimal getKapacita() {
return this.kapacita;
}
public void setKapacita(BigDecimal kapacita) {
this.kapacita = kapacita;
}
public Set getSanitaris() {
return this.sanitaris;
}
public void setSanitaris(Set sanitaris) {
this.sanitaris = sanitaris;
}
}
And routes that mannipulate with them.
nemocnicaRoute:
#Path("nemocnica")
public class nemocnicaRoute {
// private static final helper db = new helper();
#GET
#Path("all")
#Produces(MediaType.APPLICATION_JSON)
public String getName(){
List<Nemocnica> l = db.helper.getNemocnicas();
GsonBuilder builder = new GsonBuilder();
Gson gson = builder.create();
//System.out.println( json );
//return l.toString();
return gson.toJson(l);
}
// another methods
}
sanitkaRoute
#Path("sanitka")
public class sanitkaRoute {
//private static final helper db = new helper();
#GET
#Path("all")
#Produces("text/plain")
public String getName(){
List<Sanitka> l = db.helper.getSanitkas();
GsonBuilder builder = new GsonBuilder();
Gson gson = builder.create();
//System.out.println( json );
//return l.toString();
return gson.toJson(l);
}
// another methods
}
I am using these two getName() methods to retrieve all data from said tables.
This cause strange behavior , if i invoke get request on nemocnicaRoute first , it works very well as it should.
However when i invoke get requet on sanitkaRoute first , it works but after that when i want to invoke get request on nemocniceRoute it throws
java.lang.UnsupportedOperationException: Attempted to serialize
java.lang.Class: org.hibernate.proxy.HibernateProxy. Forgot to
register a type adapter?
Which confuses me , bcs this does not happen when i invoke getRequest on nemocnicaRoute first.
How could i fix this strange behavior?
All help appreciated

Your expected result list will contain elements that are list of profiles, not profiles.
I would replace Profil.class by List.class for the Query creation :
List<List<Profil>> listProfil = Arrays.asList(manager_.createQuery("select t.profil_tournee "
+ "FROM Tournee t WHERE t.nom LIKE :tournee", List.class)
.setParameter("tournee", tournee)
.getResultList());

Your error gives you a hint that the returning type should be consistent with declared type when invoking EntityManager.createQuery(query, Type) method:
List<SomeType> em.createQuery("SELECT s FROM SomeType", SomeType.class);
However your real problem is that your query is illegal. In JPA collection-valued expressions cannot be part of SELECT clause. Please see another answer of mine https://stackoverflow.com/a/25890863/3796586.
The solution in your case would be to reverse the query like this:
List<Profil> result = em.createQuery("SELECT p FROM Profil p WHERE" +
"p.profil_tournee.norm LIKE :tournee", Profil.class)
.setParameter("tournee", tournee)
.getResultList());

Hibernate needs a constructor with at least package private (i. e. default) visibility.
Normally a parameterless constructor is necessary (which you implicitly have), but for your select new ... SellerDetailsDto needs a constructor with the 15 parameters which you give in the select statement. (Thought the error message demands a constructor with only the id as a parameter - it looks like if the error is coming from a different select new statement.) You don't have such a constructor.

The problem is that you don't have a constructor in SellerDetailsDto that accepts the parameters that you are passing in the hql query. Add this constructor to your class:
public SellerDetailsDto(String productId, String sellerId,
String sellerSku, Double sellPrice, Double transferPrice,
Double sellerMRP, Double tradusCommission, Double baseShippingFee,
Double addnShippingFee, String propogationLevel,
String propogationValue, String warehouseName, int quantity,
int maxShippingTime, int minShippingTime) {
this.productId = productId;
this.sellerId = sellerId;
this.sellerSku = sellerSku;
this.sellPrice = sellPrice;
this.transferPrice = transferPrice;
this.sellerMRP = sellerMRP;
this.tradusCommission = tradusCommission;
this.baseShippingFee = baseShippingFee;
this.addnShippingFee = addnShippingFee;
this.propogationLevel = propogationLevel;
this.propogationValue = propogationValue;
this.warehouseName = warehouseName;
this.quantity = quantity;
this.maxShippingTime = maxShippingTime;
this.minShippingTime = minShippingTime;
}
This could make some other code you have to stop working, because now there wont' be a default constructor available. To fix that, add a default constructor too:
public SellerDetailsDto() {}

Actually this is problem on your root pom file. You want install lombok in your IDE & add dependency of lombok in root pom file I hope it will work

Passing a Collection of Java Beans as DataSource to Jasper, How to design this in ireports

I need to design a report, that displays the data from a collection(Say List). This list contains multiple POJOs.
The POJOs are populated by the data access layer of the application. How do I design a report template for this requirement in iReports?

Use JRBeanCollectionDataSource for your report.

Ok! Found the answer. The steps are as below.
Compile the bean classes and create a JAR file. This needs to have the complete package
Add this jar to the LIB folder in ireports
Create a factory/wrapper class that has a createBeanCollection method that populates a collection
Use this class's top level package as the class path in ireports
Use this class as the JavaBean datasource with the method.
Once all this is done, create a report with the new datasource and in report query, give the FQN on the Java bean and add the desired field.

BankDetailsList list = new BankDetailsList();
ArrayList<BankDetails> lst = list.getDataBeanList();
JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(lst);
Here BankDetails is a POJO
public class BankDetails {
public String bank_name;
public Account account;
public String custodian_account;
public String custodian_name;
public String agreement_type;
public double exposure;
public double collateral;

}
}
Account POJO:

this.account_id = acc_id;
this.account_name = acc_name;
}
