With struts1 you can use JSTL EL, too. The form bean names are available 
in EL. And struts1 has it's own tag lib.

replace Java scriptlets in JSP page

[Albert Kao]

The following Java scriptlet code in a Struts jsp is working fine. 
However, is it possible to change the jsp code so as to remove all the Java 
scriptlet codes? 

The .jsp code is like this:<%
  HttpSession httpSession = request.getSession(true);
  MyClient myClient = (MyClient)httpSession.getAttribute(MyConst.MY_CLIENT);
%>

  <%
    pageContext.setAttribute("requiredIndex", myClient.getRequiredIndex(index), 
PageContext.PAGE_SCOPE);
  %>
  
     <%= myClient.getNumber(index) %>
  

  
    
  
    
    
  
    
    
  ">
    
  
    
    
  



The java code is like this:public class Owner implements java.io.Serializable {
    private static final long serialVersionUID = 7920764268572909394L;
    private String lastName;
    private String ownershipCode;
    //...
    
    public Owner() {
    }

    // getter and setters
    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    //...
    public Integer getRequiredIndex(Integer index) {
        Integer requiredIndex = index;
        if (OWNRSHP_PARTNER.equals(ownershipCode)) {
            requiredIndex = requiredIndex - 1;
        }
        return requiredIndex;    
    }

    public String getNumber(Integer index) {
        String number = Integer.toString(index + 1);
        if (OWNRSHP_SOLE.equals(ownershipCode)) {
            number = "";
        } 
        return number;    
    }
}
