title: Change fielderror color?
body: <p>I am using struts2 validation using the <code>validate()</code> method in my Action class. 
  I add FieldErrors using <code>addFieldError()</code> method. The field error gets displayed on top of each field of my form.</p>
  
  <p><strong>Action class:
  (This validates setMapServerDetails action)</strong></p>
  
  <pre><code>/*---------------------VALIDATION------------------------------------*/
  public void validateSetMapServerDetails(){
  
      if(getMapServer().getServerName().length() == 0){
          addFieldError("mapServer.serverName", "Name is Required");
      }
  }
  </code></pre>
  
  <p>The problem is the error gets displayed in plain text, I want the error in red color.</p>
  
  <p>How should I change it to red?</p>
  
  <p><strong>EDIT:</strong> 
  JSP:</p>
  
  <pre><code>&lt;title&gt;Configure Map Server&lt;/title&gt;
  
  &lt;s:head /&gt; 
  &lt;/head&gt;
  &lt;body&gt;
  
  &lt;s:form action="setMapServerDetails" validate="true"&gt;
      &lt;s:textfield name="mapServer.serverName" label="Server Name"&gt;&lt;/s:textfield&gt;
      &lt;s:textfield name="mapServer.serverIp" label="Server IP"&gt;&lt;/s:textfield&gt;
      &lt;s:textfield name="mapServer.serverPort" label="Server Port"&gt;&lt;/s:textfield&gt;
      &lt;s:textfield name="mapServer.applicationName" label="Application Name"&gt;&lt;/s:textfield&gt;
      &lt;s:textfield name="mapServer.remarks" label="Remarks"&gt;&lt;/s:textfield&gt;
      &lt;s:submit value="Save"&gt;&lt;/s:submit&gt;
  &lt;/s:form&gt;
  </code></pre>
