<h:outputText value="#{'I love JSF'.contains('JSF')}" /> <!-- true -->

OR

<h:outputText value="#{myBean.text.contains('some_word')}" />

There is no such method. However you can similarly use other java `String` methods. So you can implement case insensitive `contains` feature like this. `#{'i love JSF'.toLowerCase().contains('JSF'.toLowerCase())}` – prageeth Dec 03 '12 at 11:32

In addition you can use JSTL functions

Add this:

xmlns:fn="http://java.sun.com/jsp/jstl/functions"

And use it like this

render="#{fn:contains(myBean.myText, 'test')}"
