You need to create custom implementation of TextProvider and override getText methods in it.

1) Create class (e.g. EmptyDefaultTextProvider) extending one of TextProvider existing implementations (e.g. TextProviderSupport).

2) Override all getText methods like that:

public String getText(String key, String defaultValue) {
     return super.getText(key, "");
}

3) Use your custom class as the default text provider. Put below in struts.xml.

<constant name="struts.xworkTextProvider" value="emptyDefaultTextProvider" />

<bean type="com.opensymphony.xwork2.TextProvider" name="emptyDefaultTextProvider" 
                              class="packagepath.EmptyDefaultTextProvider" scope="default" />
