<h:message for="fieldName" />

it always appear on the end of the screen with no style

I want to hide the messages summary even if I don't handle those validations

I guess they are just warnings that you see when your project stage is set to Development .

In web.xml file, change:

<context-param>
  <param-name>javax.faces.PROJECT_STAGE</param-name>
  <param-value>Development</param-value>
</context-param>

to:

<context-param>
  <param-name>javax.faces.PROJECT_STAGE</param-name>
  <param-value>Production</param-value>
</context-param>

and the messages disappear.

It is a feature of JSF 2 that shows you diagnostic messages when you are on Development stage. Actually you should changed that value in web.xml only when you want to put the project in production.
