Hello there. I have written a Bean that checks on a form validation and
then writes appropriate error messages in a hashtable. I have declared the
hashtable as :
private Hashtable errorMessages = new HashTable().
I call the proper setter and getter methods:
if (something)
{
setErrorMessage("error", "test error message");
}
public void setErrorMessage(String aKey, String aValue)
{
errorMessages.put(aKey, aValue);
}
public String getErrorMessage(String message)
{
String error = (String) errorMessages.get(message.trim())
return error;
}
The thing is that every time I call the getErrorMessage("error") from
inside a jsp page - lets say my instance of the bean is called Error: I then
use
<%=Error.getErrorMessage("error")%>
it returns nothing. The hashtable has no values at all. If I write two test
lines like:
System.out.println("Hashtable :" + errorMessages);
then the one in the setter method returns:
Hashtable {error=test error message}
while the one in the getter method returns:
Hashtable {}
Something must be happening between the setting and the getting of the error
message. Can it be possible that a new instance of the hashtable is being
created every time? Is there any way to get the hashtable's id?Any
suggestions are more than welcome.
Thank you.
Panos
