大姐！！！！bean在web中不可以直接使用，你只能在JSP中或servlet中调用，如果你写的是servlet，你的在web.xml中配置！OK明白了吗？如果不明白，在留言!

我是在JSP中调用的，上面的JAVABEAN运行步骤有问题吗，它的ID是这样设置的[jsp：useBean class = "yourBeanName（也就是你的class文件）" id = "thebean" scope = "session"

我相知道出错的信息是什么？还有一样，javaBean在放入classes后，应用服务器必须重新起动！
我的QQ是15934543，还是不明白加我！加入时请说明“我是java爱好者“，那我才加知道你是谁！

org.apache.jasper.JasperException: Unable to compile class for JSP

No Java compiler was found to compile the generated source for the JSP. 
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK 
to the common/lib directory of the Tomcat server, followed by a Tomcat restart. 
If using an alternate Java compiler, please check its installation and access path.
