I'm new to JSF (just started learning about it 4 days ago) and I'm a bit confused about the usage of h:outputText. I know that is a simple tag, but in most examples I've seen, it's used to output very simple (no need to escape), non-i18n text. For example (taken from here)
<h:outputText value="Transport" />
which could be replaced by
Transport
So, I'm wondering if I'm missing something or if most of the examples I've seen are overcomplicated to the point of insanity.
The h:outputText tag renders an HTML text.
JSF <h:outputText> TagIt is used to render a plain text. If the "styleClass", "style", "dir" or "lang" attributes are present, render a "span" element. If the "styleClass" attribute is present, render its value as the value of the "class" attribute.
If you're using JSF 2.x with Facelets 2.x instead of JSP, then both are equally valid. Even more, Facelets implicitly wraps inline content in a component as represented by <h:outputText>
(in other words, it will be escaped!).
Only whenever you'd like to disable escaping using escape="false"
, or would like to assign id
, style
, onclick
, etc programmatically, or would like to use a converter (either explicit via converter
or implicit via forClass
), then you need <h:outputText>
.
I myself don't use <h:outputText>
whenever it is not necessary. Without it, the source code becomes better readable. You can just inline EL in template text like so #{bean.text}
instead of doing <h:outputText value="#{bean.text}">
. Before JSF 2.0, in JSP and Facelets 1.x, this was not possible and thus the <h:outputText>
is mandatory. If your IDE gives warnings on this, it's most likely JSF 1.x configured/minded.
