要命的Tomcat！！！！！救我！

作了一个jsp程序（用到了java bean）出了这么多问题：

那位兄台救救我！

[woowindice]

无法编译java bean

[sorry2000]

那是什么原因啊？
为什么呢？

[sorry2000]

难道是因为引用的java bean有什么问题么？
但是不可能啊，java bean 都是编译通过了的啊

[guo_dongliang]

because of your Tomcat,
you should install Tocat again

[jspxnet]

一定是你程序的问题。

[sorry2000]

这个TomCat是我新装的，怎么办啊

[ggyy]

paste your jsp code
by the way:
can you vist the tomcat in your IE with the http://localhost:8080?

[sorry2000]

http://localhost:8080没问题啊。
而且错误是出现在我重新编译了javabean之后,jsp文件也作了小的修改（因为接口稍微改动了一下）。

现在要是将原来的jsp文件及class文件恢复，系统还能用--这才是我最困惑的地方。

肯定可以排除是语法错误，因为只是class的一个方法增加了一个参数，所以jsp的改动很小。

[sorry2000]

最头疼的是返回的错误让我云里雾里！
不知所云

你注意这个，有可能你还有.parseInt错。。。

[demonangel]

同上 100％ 是你的Integer.parserInt(。。。) 出了问题
在用这类函数之前至少要try 一下！

[comlook]

我也有这类的问题，请大家一起解决
iis和tomacat4的集成成功,可浏览htm,普通jsp,
但用ie浏览一连接数据库的jsp页面却出下列错,请高手解答

[sorry2000]

to demonangel(demon) :
我还没弱到这种程度.

[leo_zhangfh]

我也碰到过这个问题。
不是parseInt的问题，因为在得的程序里根本就没有用到过这个东东

问题是出在引用bean的时候。
仔细检查一下吧

[chinesealbert]

首先你的编译通过的javabeans是否放置到了web-inf/classes/下
其次你的javabeans的scope不要超出scope
最后，注意你的server.xml里的这一行
<classpath id="WEB-INF/classes" source="WEB-INF/classes" compile="false" />
false改为true，便于调试，记住，调试完了改回来

如果以上都没有问题，那就是你的程序有问题了，细细检查你的程序吧

[sorry2000]

thank you!
还是你比较尊重我的问题。
我会试一试的。给你加分。 chinesealbert(chinesealbert)

[sorry2000]

暂时不能加分，
呆会儿给你
