Hi Antonio,
I have Tiles 2.2.1 starting up ok under Google App Engine (gae), but
I'm running into problems.
So I constructed a simple example (based on how I used to do things
with Tiles 2.0.6) to try to figure things out.
[The exception is copied at the end of this email.]
I have the following pages and files in my gae project:
~war/abc.jsp [this will be the browser target]
------
<%@ page contentType="text/html;charset=UTF-8" language="java"
session="false" %>
<%@ taglib uri="http://tiles.apache.org/tags-tiles"; prefix="tiles"%>
<%@ page import="com.myapp.*" %>
<tiles:insertDefinition name="xyz1" />
======================================
~war/WEB-INF/tiles-defs.xml
------
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE tiles-definitions PUBLIC
"-//Apache Software Foundation//DTD Tiles Configuration 2.0//EN"
"http://tiles.apache.org/dtds/tiles-config_2_0.dtd";>
<tiles-definitions>
<definition name="xyz1" template="/layouts/
test.jsp">
<put-attribute name="page_title" value="My Page" />
</definition>
</tiles-definitions>
======================================
In ~war/WEB-INF/web.xml:
------
<servlet>
<servlet-name>tiles</servlet-name>
<servlet-class>org.apache.tiles.web.startup.TilesServlet</
servlet-class>
<init-param>
<param-name>
org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG
</param-name>
<param-value>
/WEB-INF/tiles-defs.xml,/org/apache/tiles/classpath-
defs.xml
</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
======================================
~war/layouts/test.jsp
------
-ge contentType="text/html;charset=UTF-8" language="java"
session="false" %>
<%...@page import="java.net.URLDecoder"%>
<%@ taglib uri="http://tiles.apache.org/tags-tiles"; prefix="tiles" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd
">
<html>
<head>
<title><tiles:getAsString name="page_title"/></title>
</head>
<body>
<h1><tiles:getAsString name="page_title"/></h1>
</body>
</html>
======================================
However, when I attempt to access http://localhost:8888/abc.jsp, I get
the exception
copied below. Can you see what I'm doing wrong?
Thanks in advance,
Ken
