Hi,all.
can you help me to develop my first web app,with seam,but without EJB and any DataBase(or called Datasource),Thanks very much at first.
I used the seam command to generate a project,but i think the folder structure is too bad,so i change the todo example to project login:

login
-src
--org.jboss.seam.example.todo.Login.java
-web
--index.html
--login.jsp
--WEB-INF
---web.xml
---components.xml
---faces-config.xml
---lib
----All lib from example folder(size is 23MB)---

and following is changed file:
----------------components.xml-----------------------------
<!DOCTYPE components PUBLIC
"-//JBoss/Seam Component Configuration DTD 1.2//EN"
"http://jboss.com/products/seam/components-1.2.dtd">





-----------faces-config.xml-----------------------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config
PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"
"http://java.sun.com/dtd/web-facesconfig_1_0.dtd">
<faces-config>

</faces-config>

I deployed this project to tomcat 5.5,and startup the sever.no exception throws,but when to show this page use /login/login.seam.the sever will throw many exception likes follow:
