Given this code,

<rich:dataTable id="list" value="#{testBeen.dataModel}" var="test" rows="#{testBeen.dataModel.pageSize}">
    ...
    <h:outputText value="#{test.WEEK}" />

I need to manipulate the #{test.WEEK} and replace character ) with ], how can I do this?

I tried the following, but it does not work: 

<%String a = test.WEEK; a.replace("a", "b"); %>
<%=a %>

How can I get the string from JSF and pass it back to JSF?

For this particular simple purpose, I'd just use the JSTL functions taglib. There's a fn:replace() function.

E.g.

<%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
<h:outputText value="#{fn:replace(test.WEEK, ')', ']')}" />

You should for sure never use scriptlets <% %> in JSF pages.

    and for xhtml, you can just add it to the html tag like xmlns:fn="http://java.sun.com/jsp/jstl/functions" too. It's a great resource ;-) –  Jan 20 '14 at 17:37

You could write a custom Converter and parameterize it by search and replace string. See this introduction JSF for nonbelievers: JSF conversion and validation

Good practice would be to do this in the bean rather than the facelet.
