can Struts tags create a bean using constructor instead of setter

[Jonathan]

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
