Hallo,
in order to convert inputs in h:inputtext from the WebPage to the class
java.util.Date
JSF uses the standard converter javax.faces.convert.DateTimeConverter.
We would like to change this standard converter to my own imlementation. So we
would not be forced to add a converter-id to every h:inputtext binded to a
date-member.
Reason for the custom converter:
We use a database that cannot persist dates before the year 1753 and after the
year 9999. We would like to prevent the user writing such dates already from
the webpage.
Because we have to deliver the app to different customers we deploy to
WildFly13/mojarra 2.2 and WebSphhere 9.0/myfaces 2.2.
According to my investigation I created a own converter class and annotated it
like this:
@FacesConverter(forClass = java.util.Date.class)
public class MyDateConverter extends DateTimeConverter
{
But in this way the standard converter used by jsf was not changed.
Then I added manually my own converter to the Application in an post construct
method of an application scoped bean, that is created directly with the first
request to my application:
@PostConstruct
void initAppBean()
{
FacesContext.getCurrentInstance().getApplication().addConverter(java.util.Date.class,
"de.safir.web.jsf.converter.MyDateConverter");
Now the standard converter used by jsf is set to my own class.
My question:
Is this the approriate way to change the standard converter class?
Thanks,
Georg
