Define a property for your bean that resets all the other properties,
e.g.
package com.mycompany;
public class MyBean {
private String myProperty;
public void setMyProperty(String s) {
myProperty = s;
}
public void setReset(String s) {
myProperty = null;
}
}
and then in the JSP page:
<jsp:useBean id="myBean" class="com.mycompany.MyBean" scope="session" />
<jsp:setProperty name="myBean" property="reset" value="ignored" />
<jsp:setProperty name="myBean" property="*" />
The first setProperty resets all properties and the second set all
properties matching request parameters from the form.
