p:message change text of message

Question

I created a form with an which is mapped to MyBean.beansField. I used the javax.validation.NotNull anotation to make sure it has to be entered. Everything works fine so far but the error message looks like:

beansField: can not be null.

Whatever I tried so far I couldn't remove the "beansField: " in front of the message.

Can anyone please tell me where this prefix comes from and how I can get rid of it?

Answer 1

If you want to check if user entered data, you could alternatively use the required attribute of an input field in combination with the requiredMessage field, e.g. for an inputField:

<h:inputText value="#{myBean.beansField}" required="true" requiredMessage="Can not be null"/>

If you want to overwrite messages in general you have to edit or overwrite the messages.properties file:

1. Add this to your faces-config.xml inside the application element:

<locale-config><default-locale>en</default-locale></locale-config>
     <message-bundle>/resources/messages</message-bundle>

1. Put a file called messages_en.properties in your resources folder

2. Add messages you want to overwrite in this manner:

   javax.faces.component.UIInput.REQUIRED=Field ''{0}'' cannot be empty.

Answer 2

add ValidationMessages.properties in your classpath (WEB-INF/classes or resources if using maven structue)

add

myapp.custommessage.notNull=your custom message

and annotate like

@NotNull(message="{myapp.custommessage.notNull}")
