Replace scriptlet in a JSP page

[Dirk Behrendt <sc...@web.de>]

Hello!
 
I have read the discussion about tag libs.
 
No logic should be in a JSP page to fullfill the MVC concept. But I dont
know how to replace the following scriptlet in my JSP.
 
<%SetUpLanguages l = new SetUpLanguages(request);%>
 
It is absolutely necessary form e application.
 
Thank you!
 
Dirk

Can you rewrite SetUpLanguages to take an empty constructor?  If you can,
then you can use jsp:setProperty to take what you need from the request
object and put it in a Java Bean.

SetUpLanguages.java
---
package myclasses;
public class SetUpLanguages implements java.io.Serializable
{
    public SetUpLanguages() {}

    private String contentLanguage;
    public String getContentLanguage() {
 return contentLanguage;
    }
    public void setContentLanguage(String _contentLanguage) {
 contentLanguage = _contentLanguage;
    }
}

the JSP
---
<jsp:useBean id="setUpLanguages"
             class="myclasses.SetUpLanguages"
             scope="session" />
<jsp:setProperty name="setUpLanaguages" property="contentLanguage"
    value='<%= request.getHeader("Content-language"); %>' />
