c:set for bean properties

I'm looking for some piece of code for setting a property in a JSF managed bean. My first idea was something like that:

<c:set var="#{loginBean.device}" value="mobil"></c:set>

That means I want to set the attribute device to the value "mobil" without a button have to been clicked.

Solution

  • Yes, you can use c:set for this purpose.

    <c:set value="mobil" target="#{loginBean}" property="device" />

    However, setting a static value rarely makes sense. You might consider to set a default value directly in your managed bean class. Also in terms of maintainability since you can handle constants better in the Java code than in the view layer.
