I have made a new Seam validator:
package validators;
import java.io.Serializable;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.component.UIInput;
import javax.faces.context.FacesContext;
import javax.faces.validator.ValidatorException;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.faces.Validator;
import org.jboss.seam.annotations.intercept.BypassInterceptors;
import org.jboss.seam.log.Log;
import org.jboss.seam.log.Logging;
@Name("roCountyValidator")
@Validator
@BypassInterceptors
public class RoCountyValidator implements javax.faces.validator.Validator,
Serializable {
/**
*
*/
private static final long serialVersionUID = -3876319398131645955L;
Log log = Logging.getLog(RoCountyValidator.class);
public void validate(FacesContext context, UIComponent component,
Object value) throws ValidatorException {
log.info("validating....!");
if (String.valueOf(value).equals("Arad"))
((UIInput) component).setValid(true);
else {
((UIInput) component).setValid(false);
FacesMessage message = new FacesMessage();
message.setDetail("Invalid county");
message.setSeverity(FacesMessage.SEVERITY_ERROR);
throw new ValidatorException(message);
}
}
}
The problem is that I do not know how to use it directly from jsf...
The following does not work....
I have declared it in a special taglib file: myvalidators.taglib.xml
<facelet-taglib>
<namespace>http://example.com/jsf/my/validators</namespace>
<tag>
<tag-name>roCountyValidator</tag-name>
<validator>
<validator-id>roCountyValidator</validator-id>
</validator>
</tag>
and tried to use it like:
<h:inputText id="someField" value="#{booking.creditCardName}"
required="true" label="County">
<my:roCountyValidator/>
<h:message for="someField"/>
</h:inputText>
Can you tell me where I am wrong?
Thanks.
Two ways to solve this.
One, is to use as @BalusC has written. You don't need to define anything in faces-config.xml
Here you can even bind the old credit card number, if you want to check that also.
Then in your validate method:
The other way, is to use the
validator
tag in<h:inputText>
You don't even need to create a
@Validator
class, as long as it's a seam component and if you use the same method signature.I use a validator component for all my general validators
Now you can add the validator:
