issue in displaying the body content(fetched dynamically) of the h:dataTable

[Rani Subramani]

Hi All,

I need to display a table for which no: of columns is fixed but the
values of those columns is
fetched dynamically and the filled.


I am using <h:dataTable> for displaying but, the problem is only the
header is displaying..
the body (ie the values fetched dynamically) are not displayed. I am
not able to figure out the reason for not displaying . Since, i have
set the bean and the DTO classess correctly..


Can anybody help me to solve this problem....

these are my pages


search.jsp
--------------------


<h:dataTable
value="#{responseBean.responseDTO.resultData}" var="result"
cellpadding="5" cellspacing="7" border="10"
width="80" headerClass="header"
rowClasses="odd-row,even-row">


<h:column>
<f:facet name="header">
<f:verbatim>
<hutputText value="Flights Name"


styleClass="headerNames"></hutputText>
</f:verbatim>
</f:facet>
<hutputText value="#{result.flightNames}" styleClass="names" />


</h:column>


<h:column>
<f:facet name="header">
<f:verbatim>
<hutputText value="Flights number"


styleClass="headerNames"></hutputText>
</f:verbatim>
</f:facet>
<hutputText value="#{result.flightNumber}"


styleClass="names" />
</h:column>
</h:dataTable>


Response Bean Class
----------------------------------------


public class ResponseBean {


private AvailableFlightsDetailsDTO responseDTO = null;
AvailableFlightsDetailsDTO availDetails = AvailableFlightsDetailsDTO
.getInstance();


public ArrayList<ResultBean> searchResult() {
return availDetails.setResult();


}


public AvailableFlightsDetailsDTO getResponseDTO() {
return responseDTO;
}


public void setResponseDTO(AvailableFlightsDetailsDTO responseDTO) {
this.responseDTO = responseDTO;
}



}


This is that Response DTO class
--------------------------------------------------------

public class AvailableFlightsDetailsDTO implements Serializable {


private List<SearchFlightsResponseDTO> flightDetails;
private ArrayList<ResultBean> resultData;


public static AvailableFlightsDetailsDTO S_INSTANCE = new
AvailableFlightsDetailsDTO();


private AvailableFlightsDetailsDTO(){};


public static AvailableFlightsDetailsDTO getInstance(){
return S_INSTANCE;
}


public List<SearchFlightsResponseDTO> getFlightDetails() {
return flightDetails;
}


public void setFlightDetails(List<SearchFlightsResponseDTO>
flightDetails) {
this.flightDetails = flightDetails;
}


public ArrayList<ResultBean> getResultData() {
flightSearchList();
return resultData;
}


public void setResultData(ArrayList<ResultBean> resultData) {
this.resultData = resultData;


}


public ArrayList<ResultBean> setResult() {


ArrayList<ResultBean> list = new ArrayList<ResultBean>();
list = flightSearchList();
Iterator iterator = list.iterator();


while (iterator.hasNext()) {
Object obj = iterator.next();


ResultBean result = new ResultBean();
result = (ResultBean) obj;


}
return list;
}


// Mock flightSearchList method


public ArrayList<ResultBean> flightSearchList(
) {


List<SearchFlightsResponseDTO> dtoList = new


ArrayList<SearchFlightsResponseDTO>();
resultData = new ArrayList<ResultBean>();
dtoList =this.getFlightDetails();
//System.out.println(""+dtoList);
Iterator<SearchFlightsResponseDTO> dtoIterator = dtoList.iterator();


while (dtoIterator.hasNext()) {
SearchFlightsResponseDTO searchDTO = dtoIterator.next();
ResultBean bean=new ResultBean();
bean.setArrivalLocationCode(searchDTO.getArrivalLocationCode());
bean.setDepLocationCode(searchDTO.getDepLocationCode());
bean.setFlightNames(searchDTO.getFlightName());
bean.setFlightNumber(searchDTO.getFlightNumber());
resultData.add(bean);


}


return resultData;
}



}


I actually set the dynamically fetched values in setFlightDetails. I
am able to set and get the values accordingly

config in faces-config
----------------------------------------------
<managed-bean>
<managed-bean-name>responseBean</managed-bean-name>
<managed-bean-class>
com.mindtree.tnt.flightsearch.bean.ResponseBean
</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>





Thanks & Regards

hi,
I think you are going wrong way to display the data.If you are using DTO to display the Data.
You have to make follwing changes :-
1. Make a varible of DTO class in Main Bean Class.
3. Make an array of the DTO in Main Bean Class.
2. Make Getter /Setter of DTO & List DTO in Main Bean Class.
4. set all required value in DTO.
5. Add that instance in List<DTO> for each records
6. then display this list<DTO> in JSP page.

this will make your code simple & fast .

Thanks
