Tapestry&Hibernate

[滕训华]

Why need hibernate.jar?I use tapestry5.0.11 but I do not need to integrate
with hibernate and my web.xml as follow:

 

<?xml version="1.0" encoding="UTF-8"?>

<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";>

    <display-name>

    testTape</display-name>

    

 

    

    <context-param>

       <param-name>tapestry.app-package</param-name>

       <param-value>com.test.web</param-value>

    </context-param>

    

    <filter>

       <filter-name>app</filter-name>

       <filter-class>org.apache.tapestry.TapestryFilter</filter-class>

    </filter>

    

    <filter-mapping>

       <filter-name>app</filter-name>

       <url-pattern>/*</url-pattern>

    </filter-mapping>

    

 

    

</web-app>

 

 

But why when I start the tomcat server it told me the error failed to start
the filter and when I copy the hibernate3.jar to the lib,it is ok?why?
