How can I convert a String in h:outputText? Here is the code of h:outputText:

<h:outputText value="#{item.label} : " />

I tried using this,

<s:convertStringUtils format="capitalize" trim="true"/>

But it gives me error : "no tag was defined for name: convertStringUtils"

There are several ways.

  1. Use CSS text-transform: capitalize property.

    <h:outputText value="#{bean.text}" styleClass="capitalized" />

    with

    .capitalized {
    text-transform: capitalize;
}

  2. Create a custom Converter.

    <h:outputText value="#{bean.text}" converter="capitalizeConverter" />

    with

    @Override
public String getAsString(FacesContext context, UIComponent component, Object modelValue) {
    if (modelValue == null || ((String) modelValue).isEmpty()) {
        return null;
    }

    String string = (String) modelValue;
    return new StringBuilder()
        .append(Character.toTitleCase(string.charAt(0)))
        .append(string.substring(1))
        .toString();
}

  3. Use OmniFaces' of:capitalize() function.

    <html ... xmlns:of="http://omnifaces.org/ui">
...
<h:outputText value="#{of:capitalize(bean.text)}" />

The <s:convertStringUtils> which you're trying is not from Seam. It's from MyFaces Sandbox.
