Apache Tomcat/5.5.17


请问是什么问题？

---

是不是用了javabean了，它的位置没放好.
放在WEB-INF/classes下

---

清除缓存[.work目录下]，重新启动tomcat

---

应该是javabean没有配置正确
放WEB-INF/classes下
而且要留意这些javabean是否有package结构,如果有,目录层次要匹配

---

root cause

org.apache.jasper.JasperException: Unable to load class for JSP
你有些用到的类文件没有找到，把你用到的类文件的包放到lib下，如果是单个的类文件就放到上面说的classes下的相应目录，比如你的类的包是test.mytest.Bean你就要把Bean放到classes下的test下的mytest下
