ClassCastException
HI
I have declared an object(which implements java.io.Serializable) and the number of objects of that type i am putting into a Vector. I am passing the vector to a function through remote call. which accepts this vector as List and when i am trying to cast the objects in the List to its original type, i am able to typecast the first object and i am getting java.lang.ClassCastException for the rest of the objects. One STRANGE OBSERVATION is , when i try to get the class name of the object it is returning the proper name , but when i use instanceof operator it is returing me false. WHY is this SO?
Thanks In Advance,
U can reply me back at mailto:nitin_jain@infy.com

Hi Chapel
The code is like this
for the class whose object are put into the list :
/*******************************/
import java.io.Serializable;
public class ACLObject implements Serializable
{
private String accessID;
private String accessType;
private String accessLevel;
private int priority;
ACLObject()
{
}
public String getAccessID()
{
return accessID;
}
public String getAccessType()
{
return accessType;
}
public String getAccessLevel()
{
return accessLevel;
}
public int getPriority()
{
return priority;
}
public ACLObject(String accessID, String accessType, String accessLevel, int priority)
{
this.accessID = accessID;
this.accessType = accessType;
this.accessLevel = accessLevel;
this.priority = priority;
}
public String toString()
{
return "\n This ACL Object consist of : " +
"\n Access ID: " + accessID +
"\n Access Type: " + accessType +
"\n Access Level: " + accessLevel +
"\n Priority: " + priority ;
}
public void setAccessID(String accessID)
{
this.accessID = accessID;
}
public void setAccessType(String accessType)
{
this.accessType = accessType;
}
public void setAccessLevel(String accessLevel)
{
this.accessLevel = accessLevel;
}
public void setPriority(int priority)
{
this.priority = priority;
}
}
/******************************************/
the portion of the other class where its getting failed.
/*******************************************/
for (int i= 0 ; i< tempList.size(); i++)// where tempList = List of ACLObject
{
ACLObject a = (ACLObject)tempList.get(i);
}
/****************************************/
FOR THE FIRST OBJECT IN THE LIST THE CODE IS WORKING FINE BUT FOR 2ND OBJECT AND ABOVE ITS GIVING THE ClassCastException. IF I AM CREATING THE LIST IN THE SAME CLASS WHERE I AM FETCHING THE OBJECT FROM THE LIST THE CODE IS WORKING FINE. WHAT CAN BE THE PROBLEM?
Regards
Nitin
