    JSP 2.0 tag file latest syntax doesn't work in JBoss 4.0

    Craig Johannsen Newbie

      Here is an example tag file:

      <%@ attribute name="greeting" required="true" %>
      <%@ attribute name="name" required="true" %>
      <h2><font color="black">${greeting}, ${name}!</font></h2>
      


      I try to use the tag in a simple page, such as:
      <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
      <%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %>
      
      
      <html>
       <head><title>Tag Files Example</title></head>
       <body>
       <h1>Tage Files Example</h1>
       <tags:test2 greeting="Hello" name="Craig"/>
       </body>
      </html>
      


      Deploys to JBoss 4.0.1 OK, but when accessing the above page it gets:

      java.lang.RuntimeException: org.apache.jasper.JasperException: /WEB-INF/tags/test2.tagx(1,2) The markup in the document preceding the root element must be well-formed.

      ====================
      However, older style tag files do work OK, such as the following:
      <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0">
       <jsp:directive.attribute name="a"
       type="java.lang.String"
       required="true"/>
       <jsp:directive.attribute name="b"
       type="java.lang.String"
       required="true"/>
      
       <jsp:text>A sample link: <a href="${a}"> ${b} </a></jsp:text>
      </jsp:root>
      


      Does JBoss 4.0.1/Tomcat support the newer syntax? Do I need to configure something special to enable that syntax?
