I am getting the class cast Exception as
java.lang.ClassCastException: com.model.Image cannot be cast to java.lang.String
Below is my function to get the Data from an MySQL table created by an Entity Class of JPA
public List<Image> complete(String fileName)
{
List<Image> queryResult = new ArrayList<Image>();
System.out.println("File Name is : "+fileName);
if (allImages == null)
{
System.out.println("Yeah I am coming here"+allImages);
allImages = imageFacade.findAll();
}
allImages.removeAll(servicesWithImage.getImage());
for (Image image : allImages)
{
if (image.getFileName().toLowerCase().contains(fileName.toLowerCase()))
{
queryResult.add(image);
}
}
return queryResult;
}
I have defined the allImages globally as
private List<Image> allImages;
The above complete method I am calling from an p:autoComplete of Primefaces which is
<p:autoComplete forceSelection="true"
minQueryLength="3"
value="#{servicesMB.image}"
label="#{msgs.image}"
required="true"
var="image"
itemLabel="#{image.fileName}"
itemValue="#{image}"
completeMethod="#{servicesMB.complete}"
dropdown="true" />
The findAll method in complete method is shown below :
public List<T> findAll()
{
CriteriaQuery cq = em.getCriteriaBuilder().createQuery();
cq.select(cq.from(entityClass));
return em.createQuery(cq).getResultList();
}
If I put the Print Statement in complete method I am getting what all the required data but the data is not shown on p:autoComplete and also I am getting the ClassCastException
I will edit my above complete method with print statements which something looks like
public List<Image> complete(String fileName)
{
List<Image> queryResult = new ArrayList<Image>();
if (allImages == null)
{
System.out.println("I am in If Condition");
allImages = imageFacade.findAll();
System.out.println("The Value of allImages : "+allImages);
}
System.out.println("Getter function servicesWithImage"+servicesWithImage.getImage());
allImages.removeAll(servicesWithImage.getImage());
System.out.println("allImages after removeAll method"+allImages);
for (Image image : allImages)
{
if (image.getFileName().toLowerCase().contains(fileName.toLowerCase()))
{
queryResult.add(image);
}
}
System.out.println("At the End The Value of queryResult"+queryResult);
return queryResult;
}
My Output(Shown only for method) :
