Java.lang.ClassCastException:java.lang.Double
I am trying to troubleshoot this error but I am not sure what to look for, where to find it, and what to change it to.

Hi Dr,
I followed your suggestion, but there was no casting to double in the JSP code, so I looked at the database and found 3 columns inadvertently created as "double default null" when the MSAccess mdb was exported to MySQL.
I modified the database to make those columns text, and now the compiler does not throw the error.
I'm still unclear why the error was thrown.

Java.lang.ClassCastException Ljava.lang.Object
Hi everyone,
I am a Software Engineer working in an enterprise application with the technologies Struts 2.0.11,EJB3.0 and Jasper reports3.0. In my enterprise application
I got the Exception java.lang.ClassCastException Ljava.lang.Object while casting java.util.List of getResultList() method into java.util.List<customObjectType>. I am using JPQL. Is not possible to convert an Object List to its native customObjectType List from the getResultSet() method as the following snippet
Query accountsQuery=accountsEntityManager.createQuery("select acc from BankAccount acc");
//casting Object List into BankAccount entity POJO List and this shows the baove Exception
java.util.List<BankAccount> accounts=(java.util.List<BankAccount>)accountsQuery.getResultList(); //BankAccount is an Entity POJO
Please give me reason for this Exception and solution.

In the line 36 what I have is:
nuevo_equipo.setPart((Integer)traRes.getObject(4));
The information that I spend(pass) this one to him(her) declared as an integer.
Which can be the problem? Something on having done the casting?It(He,She) it
gives me the exception java.lang.
ClassCastException: java.lang. Short,So what does the API say this means? Ever bothered to have a look?
the complete

Thanks for the help in advance..It seems you have used a taskflow on a page and one of the binding.
It will be easy to point out if you paste the code of region tag *<af:region.......*. -

I get the error at this line of code in my program.
java.util.ArrayList list= (java.util.ArrayList)obj; Don't do this cast.
Why are you doing this cast anyway? I think you need to show a small bit of compilable code (or almost compilable except perhaps for this error) and some more explanation. -
Java.lang.ClassCastException: java.lang.OutOfMemoryError
Hi everyone,
I am having this exception when I want to run my application (not always so). I have to restart the server and il works again fine.
But I don't see the relation between a ClassCastException and the OutOfMemoryError.
Can anyone tell me ?
Thanksyou're right.
I have a cast with Exception. I have not understood the OutOfMemoryError was not an exception.
So I have 2 errors : the first one is the OutOfmemory and the second one is the cast.
Do you agree ? -

Edited by: User007 on Sep 7, 2011 10:08 AMHey found the issue..
Actually i am trying to reset value of table from Bean. By default there is a value attached to table from bindings and setting another value from bean which was a POJO object.
On selection of row the casting issue raising up.
Issue is gone after removing that.
Thanks...

Runtime Error: java.lang.ClassCastException
My project is to creat a postfix with boolean. I finished my code, it compiled great, than I got an java.lang.ClassCastException. So obviously I have a casting problem. Any help or hints in the right direction would be greatly appreciated.
import java.util.*;
import javax.swing.*;
public class KimbelPostfix
public static void main(String[] args)
String expression;
String token;
String operator;
String myString = "true";
StringTokenizer tokens;
Boolean operand1, operand2, result = true;
//create empty stack of pending boolean operands
Stack operandStack = new Stack();
expression = JOptionPane.showInputDialog( "Enter postfix expression" );
tokens = new StringTokenizer(expression);
while (tokens.hasMoreTokens())
token = tokens.nextToken();
if (!isOperator(token)) //operand
new Boolean(myString);
myString = token;
operandStack.push(token);
// printStack(operandStack); //display stack at each step. Debugging
else
{ //token is an operator
//pop two booleans off stack.
//convert popped Object to boolean, extract boolean
operand2 = ((Boolean)operandStack.pop()).booleanValue();
operand1 = ((Boolean)operandStack.pop()).booleanValue(); //"first" one
if (token.equals("!"))
operandStack.push(token);
result = operand1 && !operand2;
else if (token.equals("&&"))
result = operand1 && operand2;
else if (token.equals("||"))
result = operand1 || operand2;
operandStack.push(new Boolean(result));
//only object in stack is the answer
result = ((Boolean)operandStack.pop()).booleanValue();
JOptionPane.showMessageDialog(null,expression+" = "+result);
System.exit(0);
static boolean isOperator(String t) {
if (t.equals("!") || t.equals("&&") || t.equals("||"))
return true;
else
return false;
static void printStack( Stack s)
System.out.print("Stack is: ");
Iterator items = s.iterator();
while (items.hasNext())
System.out.print(items.next()+" ");
System.out.println();
When I run the program and enter "false false ||" I get the slightly more useful error message:
Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean\\ at KimbelPostfix.main(KimbelPostfix.java:38)Now line 38 is the one in the else part of the while loop, that says:operand2 = ((Boolean)operandStack.pop()).booleanValue();Evidently what you were casting to a Boolean - operandStack.pop() - is a String. And you can't cast Strings to Booleans like that. So the questions are "what were you expecting to be on the stack?" and "what was actually on the stack?".
You already have a method that will help answer the second question. As regards the first, if you were expecting a Boolean on the stack you had better go back to whereever you push things onto the stack and see why it's a String not a Boolean.

I've just read the edit of your last post, and I agree with petes1234. No-one here is going to write the code for you. That's not trying to be discouraging or dismissive: just saying how things are.
There are signs of dispair in the myString variable, and the way you (attempt to) handle the unary ! operator. If you're tired and "fiddling around" to no productive effect your best bet would be to step away from the computer and do something else for a few hours. -

ThanxYou don't want to select the columns, you want to select the object itself.
SELECT u FROM Unit u ORDER BY u.unitName
or even shorter:
FROM Unit u ORDER BY u.unitName
Try to reason where to put your question by the way, it is not about Javaserver Faces. If you can't find a forum that clearly matches consider putting it in Java Programming. In this case it was entirely unnecessary since you already posted JPA questions in the EJB forum, which is a decent match. -
