初学jsp+javabean时的问题 找不到class
我的一个JSP+Javabean的练习放在如下路径
D:\J2ee\Apache Software Foundation\Tomcat 6.0\webapps\Jsp\exercises
useBean -folder 下面
-[WEB-INF] ---> Folder
-classes ----> folder
- tax ----> folder
-TaxRate.class
- TaxRate.java
-UseBean.jsp
-settax.jsp
UseBean.jsp

如果将appBase改为如下后重启Tomact
.\Tomact6.0\conf\Server.xml 中<host 部分的缺省如下
<Host name="localhost" appBase="webapps\Jsp\exercises" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
