按照http://jakarta.apache.org/turbine/tdk/tdk-howto.html生成的newapp项目在http://localhost:8080/newapp/servlet/newapp中不能跑，需要修改web.xml如下：
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app

</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Templates</realm-name>
</login-config>
</web-app>
注意仅仅修改了<servlet-mapping/>的映射关系即可
