请教如何注册一个类

graydream · 发表于 2005-4-22 21:37:34

我写了一个监听session的类，编译成class，放在~/myweb/jsp/WEB-INF/classes/里，这里放的bean都是可以找到的。也配置了classpath

echo $CLASSPATH
/home/gray/myweb/jsp/WEB-INF/classes/:/opt/blackdown-jdk-1.4.2.01/lib:/opt/blackdown-jdk-1.4.2.01/jre/lib:/opt/blackdown-jdk-1.4.2.01/lib/tools/jar:.

复制代码

在web.xml的<webapp>标签下填写

<listener>
<listener-class>SessionControl.userListener</listener-class>
</listener>

复制代码

但是日志提示找不到类，这是catalina.out

应该放到 ~/myweb/jsp/WEB-INF/classes/SessionControl/ 这个目录下吧?

graydream · 发表于 2005-4-22 23:35:10

是啊，是这么方得，我还放到/opt/tomcat5/shared/classes/SessionControl里了，也不好用

eTony · 发表于 2005-4-22 23:53:25

注意区分大小写了吗?

graydream · 发表于 2005-4-23 10:08:12

当然了，郁闷死了

是不是需要在server.xml里配置什么呢？我从来没配置过server.xml，只是在/opt/tomcat5/conf/Catalina/localhost/里配置过

graydream · 发表于 2005-4-23 11:02:06

找到了，今天挨个文件夹放，最后竟然是放在common/classes/里

:!! :!! :ask :ask :eek: :eek:

graydream · 发表于 2005-4-23 13:23:45

差不多知道怎么回事，我是在全局的/opt/tomcat/conf/web.xml里配置的。如果在~/myweb/jsp/WEB-INF/的web.xml里配置，就可以放在~/myweb/jsp/WEB-INF/classes里
