JSF trimming white spaces

Question

HI,

I have an input field in which I want to trim any leading/trailing whitespaces. We are using JSF and binding the input field to a backing bean in the jsp using:

<h:inputText id="inputSN" value="#{regBean.inputSN}" maxlength="10"/>

My question is that besides validation can this be done in the jsp? I know we can also do this using the trim() java function in the Handler, but just wondering if there is a more elegant way to achieve this in JSF.

Thanks.

Answer 1

You could use a Converter (tutorial).

Answer 2

I resolved this by just using the trim() function in the handler before doing any processing. it just seemed like the most straight forward way of doing this.

I answered a similar question here

Basically you can either create your own component that is a copy of inputText which automatically trims, or you can extend the inputText and add trim attribute that trims if true.
