Question

Struts – Alternative of <html:errors /> to display error messages in Jsp?

Answer 1

By setting the attribute message="false" on the <html:messages /> tag, it gets all errors stored on ActionMessages list if saveErrors was called.

<logic:messagesPresent message="false">
                        <html:messages id="aMsg" message="false">
                            <logic:present name="aMsg">
                                <!-- Error -->
                                <div class="error">
                                    <bean:write name="aMsg" filter="false" />
                                </div>
                            </logic:present>
                        </html:messages>
                    </logic:messagesPresent>

The <html:messages id="aMsg" message="false"> display messages stored on saveErrors while <html:messages id="aMsg" message="true"> display messages stored on saveMessages. There is no more ActionErrors object, just ActionMessages. The ‘saveErrors’ and ‘saveMessages’ method seperates the errors and messages respectively.
