In Jakarta Struts - you may be knowing that - both are custom tags defined in HTML Tag library.

Both are used for accessing Java beans.

Bean:Message - is to access a java bean that will display a message such as " For more details on the product displayed in this web site please contact a phone number 12345.."

Bean: write - is to display a data from the model; example "Number of People visited this site is: 1234" 

Bean does not directly write. the Tag is used to take help of these Beans for the above mentioned purposes

hi

in the jsp

<% @taglib uri="/tags/struts-bean" pefix="bean" %>

<ul>

<bean:messages var="msg" property="propone">it will returns errors in the formbean tag

<li>

<bean:wrtite id="var"/>it will returns data abt the formbean

</li>

</bean:messages>

</ul>

bean:message retrieves an internationalized message for the specified locale, using the specified message key, and write it to the output stream. Up to five parametric replacements (such as "{0}") may be specified.

The message key may be specified directly, using the key attribute, or indirectly, using the name and property attributes to obtain it from a bean.

Retrieve the value of the specified bean property, and render it to the current JspWriter as a String.
