Struts Misconfiguration: Missing Form Bean Name

Java/JSP

Abstract

A form-bean without a name attribute will not be used.

Explanation

Struts uses the form-bean name to map HTML forms to actions. If a form-bean does not have a name, it cannot be mapped to an action and indicates either a superfluous definition or an accidentally omitted bean.
Here is a proper form-bean example:
Example 1: The following form-bean has an empty name attribute.


<form-beans>
  <form-bean name="" type="org.apache.struts.validator.DynaValidatorForm">
    <form-property name="name" type="java.lang.String" />
    <form-property name="password" type="java.lang.String" />
  </form-bean>
</form-beans>
