Hi,
Just as information this is the decompiled code found in Visual Age 3.5.3
We can clearly see although for reasons unknown to me that we cannot remove
Request scope attributes.
public void removeAttribute(String s)
{
attributes.remove(s);
}
public void removeAttribute(String s, int i)
{
switch(i)
{
default:
break;
case 1: // '\001'
attributes.remove(s);
break;
case 2: // '\002'
throw new IllegalArgumentException("cant remove Attributes
from request scope");
case 3: // '\003'
if(session == null)
throw new IllegalArgumentException("can't access
SESSION_SCOPE without an HttpSession");
session.removeAttribute(s);
break;
case 4: // '\004'
context.removeAttribute(s);
break;
}
}
