can Struts tags create a bean using constructor instead of setter

[Jonathan <ja...@i-2000.com>]

Are struts tags currently designed to handle this for me?:
====================================================
package com.vnu.models;

public class JumpUrlsBean extends java.lang.Object{

    private String targetUrl = null;
 private String successUrl = null;
 private String failureUrl = null;
 
 public JumpUrlsBean(String targetUrl, String successUrl, String failureUrl){
     this.targetUrl = targetUrl;
     this.successUrl = successUrl;
     this.failureUrl = failureUrl;
 }
 public String getTargetUrl(){
  return this.targetUrl;
 }
 public String getSuccessUrl(){
  return this.successUrl;
 }
 public String getFailureUrl(){
  return this.failureUrl;
 }
}
====================================================
There is purposely no setter method because it shouldnt be modifyable.  However, I want Struts to populate it for me
