I am using primefaces datatable to show some data and I would like to limit the text shown to the user. I have a description that contains hundreds of lines, but I don’t want to show more than 50 characters in the datatable before the user taps that row. How can I do this?

    Inspired by this answer you could use the JSTL function substring for this purpose:

    <%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
<h:outputText value="#{fn:substring(yourBean.text, 0, 49)}" />
