Here the code, what I don't understand is that If I put iside my tag a 
static String al works

public class MiaTagLibrary extends BodyTagSupport {

     static int cont =0;
     private String initValue="-1";
     /** Creates new MiaTagLibrary */
     public MiaTagLibrary()
     {
     }

     public void setInitValue(String nval)
     {initValue=nval;}

     public String getInitValue()
     {return(initValue);}


     public int doStartTag()
     {
         try
         {

         // Here I search barba, a String defined in the jsp

             
pageContext.getOut().print("----------------------"+pageContext.getAttribute("barba",PageContext.PAGE_SCOPE)+"<br>");
 


         }
         catch(Exception e)
         {e.printStackTrace();}

         return EVAL_BODY_TAG;
     }

     public int doAfterBody() throws JspTagException
     {
         try
         {


             BodyContent bc = getBodyContent();
             String corpo = "vuoto";
             if (bc!=null)
              corpo= bc.getString();
             getPreviousOut().print("Il tag ha corpo "+corpo);

         }
         catch(Exception e)
         {e.printStackTrace();}
         return SKIP_BODY;
     }

    public int doEndTag()
    {
         return EVAL_PAGE;
    }
}

Sorry I don't understand, I have a JSP like this

<%
         String barba="pippo";
         String p2="pluto";
...
%>

and I want to read these variables in my tag ( by the way I need to access 
all the variables defined in the jsp without knowing them ), how the 
tagExtraInfo should be written ? ( all examples I read talk about the 
opposite problem, put a tag variable into jsp ).

Thanks
