新手请教jsp网站发布问题,急!请大家帮帮忙.

[sw0924]

用jdk+tomcat搭建了环境,tomcat欢迎页面能正常显示,应该是搭建成功了的.
现在将一个jsp网站代码放在tomcat的webapps下,名字为root,现在问题是,在ie浏览器输入地址:
http://localhost:8080/,报http status 500错误.具体错误页面如下:

小妹初学看不太懂上面的意思,请大家帮我看看.谢谢了!

[昵称很不好取]

Could not initialize class com.bcxy.db.ProxoolConnection
看看这个类是不是有问题，或是存放位置是否正确

[Java773112617]

com.bcxy.db.ProxoolConnection
报的异常是你的这个类没找到 你去看哈你写的类有没问题
http status 500错误：表示你的代码有错误（404表示路径有错误）

[softroad]

找找com.bcxy.db.ProxoolConnection所在的jar，copy到web-inf/lib下

[sw0924]

我修改了部分配置过来,又出现了这样的错误,还请大家帮我看看:

xinqiao.hosipital.yjb.abteilung.CateInfoForm.getRootCate(CateInfoForm.java:500)
CateInfoForm.java:500,第500行，有问题。

[kkvoo]

请问你原来的\webapps\ROOT去哪里了？欢迎页面就是默认读取的ROOT里面的。
你放入的root怎么放的？你覆盖了ROOT？！ 估计是冲突了！！！
建议换个名字不要叫root，例如你的项目名字,bbs 之类的。
访问的时候地址为，http://localhost:8080/bbs应该能看懂吧
按照我的试一下吧

[kkvoo]

你那个500错误估计是这样的，解决了记得给分啊.

[sw0924]

结果是数据库链接错误导致的问题，谢谢大家
