Display value from db in web page using hibernate

Display value from db in web page using hibernate - java

I have a simple web application which retrives all enterys from a db table and when clicked on shows more details from other tables. I am using hibernate to map the tables but i am having a problem displaying values from foreign keys. For example i want to display the actors name associated with a movie instead of "movie.Actor#5514f9"
<h:outputText value="Actors"/>
<h:outputText value="#{movieController.selected.actors}" title="Actors"/>
Is the code i am using to display the values.
My movieController class is
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package movie;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
/**
*
* #author Shane
*/
#ManagedBean(name = "movieController")
#SessionScoped
public class MovieController {
int startId;
int endId;
DataModel movieTitles;
MovieHelper helper;
//private int recordCount = 1000;
private int pageSize = 10;
private Movie current;
private int selectedItemIndex;
public List getActors() {
List actors = new ArrayList();
return actors;
}
/** Creates a new instance of MovieController */
public MovieController() {
helper = new MovieHelper();
startId = 1;
endId = 1000000;
}
public MovieController(int startId, int endId) {
helper = new MovieHelper();
this.startId = startId;
this.endId = endId;
}
public Movie getSelected() {
if (current == null) {
current = new Movie();
selectedItemIndex = -1;
}
return current;
}
public DataModel getMovieTitles() {
if (movieTitles == null) {
movieTitles = new ListDataModel(helper.getMovieTitles(startId, endId));
}
return movieTitles;
}
void recreateModel() {
movieTitles = null;
}
// The following methods that are used for page navigation
public boolean isHasNextPage() {
helper = new MovieHelper();
if (endId + pageSize <= helper.getRecordCount()) {
return true;
}
return false;
}
public boolean isHasPreviousPage() {
if (startId - pageSize > 0) {
return true;
}
return false;
}
public String next() {
startId = endId + 1;
endId = endId + pageSize;
recreateModel();
return "index";
}
public String previous() {
startId = startId - pageSize;
endId = endId - pageSize;
recreateModel();
return "index";
}
public int getPageSize() {
return pageSize;
}
public String prepareView() {
current = (Movie) getMovieTitles().getRowData();
return "browse";
}
public String prepareList() {
recreateModel();
return "index";
}
}
And my Movie.hbm.xml file is

my current ouput is:
[movie.Actor#7b7bee, movie.Actor#10580fa, movie.Actor#3c6b88, movie.Actor#56a1b6]
but i am wondering how to display the actors name instead of the index of the actor?
any help on this would be great, thanks

Actors is a collection (set) in your case. You should iterate throw actors set and display name for each actor in collection.
"[<className>#<hashCode1>, <className>#<hashCode2>, ...]" - this is a string which method AbstractCollection.toString() returns (the movie actors set is AbstractCollection).
In turn "<className>#<hashCode>" - is a string which method Object.toString() returns (the object of class movie.Actor).
You could override method movie.Actor#toString() and make it return actor name. Then your page will render string like this: "[actor name1, actor name2, ...]".
But the correct approach is to use JSF components like <h:dataTable .../> or iterate through actor set with JSTL <c:forEach .../>.

Hibernate Query not returning anything, despite rows being present on the table

I have created this new entity on my project, and mapped it by using an hibernate.hbm.xml file, but the query never returns anything despite rows being present inside the Table. I get no errors during deploy, so i think the mapping is correct, but i don't understand why it never returns anything.
This is my code:
Entity(the getters and setters are present, i just didn't add them for brevity)
package com.rmm.lpo.be.data.model.po;
import java.util.Date;
public class ManageIotRequest implements java.io.Serializable, com.enel.framework.be.data.model.po.PersistentObject{
/**

private static final long serialVersionUID = 1L;
private Long id;
private Long lotCode;
private String transformerCode;
private String creatorUserId;
private Boolean pushLpDataRequired;
private String deviceSelectionMode;
private String fileName;
private String fileType;
private Boolean flDiscarded;
private Date completionDate;
private String errorCode;
private String detailedErrorCode;
private Date creationDate;
private Date pDate; ```

What am i doing wrong? I've also ran a query with no where conditions, just a simple select star, but it still returns nothing.

I checked my hibernate.cfg.xml file, and i found out that i hadn't mapped the entity there with the mapped-resource tag..could this be the problem?

this is what i want to do (UML): imgur
this is the link of my last error for more infos : Link
can some one help ?

Your question is a real mess... but if you read the exception:
Provided id of the wrong type. Expected: class java.lang.Integer, got class java.lang.String
Anf after you take a look to your Departement class, it has only 2 fields and one set (according to the hibernate mapping):
int id;
String nomDepartament;
Set employees;
That only can mean, youre passing the nomDepartament field instead of id somewhere in your code...
But as far as you are not providing, the Departement class or DepartementImplMetier.create() method, that is the one causing the exception I cannot say more...
So... start here focus your problems, and provide only important parts of the code.

Getting org.hibernate.MappingException

This is my first question in Stackoverflow. I'd hope be clear. I'm getting troubles with Hibernate mapping and I don't know where the error is. When I tried to run a HQL like
from Sensor
I get the following exception

Multiple occurrence of custom CompositeUserType in Hibernate causing MappingException

Hi I have the following code:
public class Trail {
private int trailID;
private Location startLocation;
private Location destination;
// Getters and setters
}
which Location is a custom DB type, it's not a table
public class LocationType implements org.hibernate.usertype.CompositeUserType {
#Override
public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session) throws HibernateException, SQLException {
if ( value == null ) {
DoubleType.INSTANCE.set(st, null, index, session);
DoubleType.INSTANCE.set(st, null, index+1, session);
DoubleType.INSTANCE.set(st, null, index+2, session);
StringType.INSTANCE.set(st, null, index+3, session);
} else {
final Location loc = (Location) value;
DoubleType.INSTANCE.set(st, loc.getLatitude(), index, session);
DoubleType.INSTANCE.set(st, loc.getLongitude(), index+1, session);
DoubleType.INSTANCE.set(st, loc.getAltitude(), index+2, session);
StringType.INSTANCE.set(st, loc.getDescription(), index+3, session);
}
}
// Other functions
}
and this is my Location class
public class Location implements Serializable {
...
}
The Trail.hbm.xml looks like this:
<hibernate-mapping package="com.mytest.walking">
<class name="Trail" table="TB_Trail" dynamic-insert="true">
<id name="TrailID" column="TrailID" >
<generator class="native"/>
</id>
<property name="StartLocation" type="LocationType" >
<column name="latitude" />
<column name="longitude" />
<column name="altitude" />
<column name="description" />
</property>
<property name="Destination" type="LocationType" >
<column name="latitude" />
<column name="longitude" />
<column name="altitude" />
<column name="description" />
</property>
</class>
</hibernate-mapping>
Then I got the following exception
Caused by: org.hibernate.MappingException: property mapping has wrong number of columns: com.mytest.walking.Trail.Destination type: com.mytest.walking.LocationType

at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1452)
Can someone point me to the right direction on how to get rid of this exception?

why not use a componentmapping
<component name="StartLocation" >
<property name="..." column="latitude" />
<property name="..." column="longitude" />
<property name="..." column="altitude" />
<property name="..." column="description" />
</property>
<component name="Destination" >
<property name="..." column="latitude" />
<property name="..." column="longitude" />
<property name="..." column="altitude" />
<property name="..." column="description" />
</property>

I found the answer. Just name the columns differently. They don't need to be same as the custom type name.
<hibernate-mapping package="com.mytest.walking">
<class name="Trail" table="TB_Trail" dynamic-insert="true">
<id name="TrailID" column="TrailID" >
<generator class="native"/>
</id>
<property name="StartLocation" type="LocationType" >
<column name="StartLocationLatitude" />
<column name="StartLocationLongitude" />
<column name="StartLocationAltitude" />
<column name="StartLocationDescription" />
</property>
<property name="Destination" type="LocationType" >
<column name="DestinationLatitude" />
<column name="DestinationLongitude" />
<column name="DestinationAltitude" />
<column name="DestinationDescription" />
</property>
</class>
</hibernate-mapping>
