we are getting a class cast exception while casting DirectorDTO into CompanyForm

List DirectorList = companyform.getDirectorData(); // returns directorDTO

(CompanyForm)DirectorList.get(i).ischecked()==true //this line shows class cast exception.



please help me to get this resolved

Hi maheshwari_siddharth,

how are we supposed to figure out this issue if we do not have any information on your data types and how they are related? Magic? Sorry, my crystal ball is currently in repair...

But I believe though that is not returning a class of any kind rather than a boolean.

BTW, this does more look like a Java question than a Hibernate one.

thanks Froestel

we have 5 directors in a table which we display in the JSP through logic iterate

now we want to delete 2 directors

we have a checkbox against each director where we select 2 and press delete button.

now we want to check in the action which two are selected out of five

this is an objective and for this we are using this code

List DirectorList = companyform.getDirectorData(); // returns directorDTO having all the directors info

Company form having a isChecked property having setter getter method

(CompanyForm)DirectorList.get(i).ischecked()==true //now we are checking which two lines are selected

but above line shows class cast exception

Hi maheshwari_siddharth,

still you provide no information on your class structure neither do you post the stack trace of your exception - how is someone supposed to help if you do not provide the necessary information???

So another guess from the following code line:

It looks like the elements of DirectorList need to be instances of the CompanyForm class to simply be able to cast. If that is case you still might have some syntax error since your cast does not seem to do what you intent. Try enclosing (CompanyForm)DirectorList.get(i) in round brackets:

This will NOT get rid of your CCE - I do not believe that the elements in your DirectorList are actually of type CompanyForm. That's not very likely. In Java you can only cast to types that are above the actual in the same class hierarchy.

... and still this is a Java question, no Hibernate question. You ended up in the wrong forum.
