Provavelmente vc esqueceu de criar o actionForm Associado ao seu action,se o seu form tiver sido criadop vê se vc configurou ele no struts-config e se ainda assi vc tiver configurado ele dá uma olhada se no teu jsp tem algum campo que não tenha no teu form ou que esteja escrito errado

da uma olhada aí no arq jsp, no ActionForm e no struts-config:

&lt;%@ taglib uri="WEB-INF/struts-html.tld" prefix="html" %&gt;

&lt;html:form action="register.do"&gt;
	UserName:&lt;html:text property="username" /&gt;<br>
	enter password:&lt;html:password property="password1" /&gt;<br> 
	re-enter password:&lt;html:password property="password2" /&gt;
	&lt;html:submit value="Register" /&gt;
&lt;/html:form&gt;

package app;
import org.apache.struts.action.*;

public class RegisterForm extends ActionForm {
	
	protected String username;
	protected String password1, password2;
	
	public String getUsername(){
		
		return username;
	}
	
	public String getPassword1(){
		
		return password1;
	}
	
	public String getPassword2(){
		
		return password2;
	}
	
	public void setUsername(String username){
		
		this.username = username;		
	}
	
	public void setPassword1(String password1){
		
		this.password1 = password1;		
	}
	
	public void setPassword2(String password2){
		
		this.password2 = password2;		
	}
	
}

<?xml version="1.0" encoding="ISO-8859-1" ?>
&lt;!DOCTYPE struts-config PUBLIC
              "-//Apache Software Foundation//DTD Struts Configuration 1.0//EN"
              "http://struts.apache.org/dtds/struts-config_1_0.dtd"&gt;

&lt;struts-config&gt;
	&lt;form-beans&gt;
		&lt;form-bean name="registerForm" type="app.RegisterForm" /&gt;
	&lt;/form-beans&gt;
	&lt;action-mappings&gt;
		&lt;action path="/register" type="app.RegisterAction" name="registerForm"&gt;
			&lt;forward name="success" path="/success.html" /&gt;
			&lt;forward name="failure" path="/failure.html" /&gt;
		&lt;/action&gt;
	&lt;/action-mappings&gt;
&lt;/struts-config&gt;

O problema estah na estrutura do seu Action

public class RegisterForm extends ActionForm

{

public ActionForward execute(

ActionMapping mapping,

ActionForm form,

HttpServletRequest request,

HttpServletResponse response) throws Exception {

... // coloque o que a classe deve fazer

return mapping.findForward("success"); 
// como estah mapeado no arquivo struts-config.xml
}

}

ah isto o que estah descrito no seu log…

O caminho pro seu action não é:

&lt;html:form action="register.do"&gt;

É:

&lt;html:form action="/register"&gt;

Veja se funciona aí.
