------解决方案--------------------
class= "test.textcounter "下面有textcounter类吗？？你是package count;呀
<jsp:useBean id= "textcounter " class= "test.count.textcounter " scope= "application " />

------解决方案--------------------
test/count目录下 textcounter.java 和textcounter.class
---------------------
你的JAVABEAN是放在 test/count目录下的
而你的调用JAVABEAN这样写 <jsp:useBean id= "textcounter " class= "test.textcounter " scope= "application " /> 当然找不到textcounter

把class= "test.textcounter " 改成 class= "test.count.textcounter "
