首先在资源文件中定义错误信息和普通信息.如:MessageResources.properties中定义如下:
java代码: 


#
# Resources for testing <html:errors> tag.
#

errors.header=<table>
errors.footer=</table>
errors.prefix=<tr><td>
errors.suffix=</td></tr>

property1error1=Property 1, Error 1
property2error1=Property 2, Error 1
property2error2=Property 2, Error 2
property2error3=Property 2, Error 3
property3error1=Property 3, Error 1
property3error2=Property 3, Error 2
globalError=Global Error

#
# Resources for testing <html:messages> tag.
#

messages.header=<table>
messages.footer=</table>

property1message1=Property 1, Message 1
property2message1=Property 2, Message 1
property2message2=Property 2, Message 2
property2message3=Property 2, Message 3
property3message1=Property 3, Message 1
property3message2=Property 3, Message 2
globalMessage=Global Message



在程序中定义错误和信息类,这个例子写在JSP中

java代码: 


<%
      ActionErrors errors = new ActionErrors();
      errors.add("property1", new ActionError("property1error1"));
      errors.add("property2", new ActionError("property2error1"));
      errors.add("property2", new ActionError("property2error2"));
      errors.add("property2", new ActionError("property2error3"));
      errors.add("property3", new ActionError("property3error1"));
      errors.add("property3", new ActionError("property3error2"));
      errors.add(ActionErrors.GLOBAL_ERROR, new ActionError("globalError"));
      request.setAttribute(Globals.ERROR_KEY, errors);

      ActionMessages messages = new ActionMessages();
      messages.add("property1", new ActionMessage("property1message1"));
      messages.add("property2", new ActionMessage("property2message1"));
      messages.add("property2", new ActionMessage("property2message2"));
      messages.add("property2", new ActionMessage("property2message3"));
      messages.add("property3", new ActionMessage("property3message1"));
      messages.add("property3", new ActionMessage("property3message2"));
      messages.add(ActionMessages.GLOBAL_MESSAGE, new ActionMessage("globalMessage"));
      request.setAttribute(Globals.MESSAGE_KEY, messages);
    %>





显示错误:
java代码: 


<html:errors property="property1" />
<html:errors property="property2" />


显示信息:
java代码: 


<html:messages property="property1" message="true" id="msg" header="messages.header" footer="messages.footer">
            <tr>
              <td>
                     <%= pageContext.getAttribute("msg") %>
              </td>
            </tr>
          </html:messages>

<html:messages message="true" id="msg" header="messages.header" footer="messages.footer">
            <tr>
              <td>
               <%= pageContext.getAttribute("msg") %>
              </td>
            </tr>
</html:messages>

For example:
public class UserDefinedTableTag   extends TagSupport
{
   private boolean isAddRichScript = false;
   public int doEndTag() throws JspException {

   
    isAddRichScript = false;
        return EVAL_PAGE;

    }
private void addNote(UserDefinedTableColumnConfig userDefinedTableColumnConfig, StringBuffer outStr) {
                if("T".equals(userDefinedTableColumnConfig.getRichHtml()))
        {
            if(!isAddRichScript)
            {
                isAddRichScript = true;
                outStr.append(richScript);
            }
            outStr.append(richHtml);
        }
            }
}
