问题描述

我已经使用Oracle ADF Essantials开发了一个Web应用程序.我可以在本地系统的tomcat 6.x上运行此应用程序.我的服务器上有相同的tomcat 6.x环境.那里都是一样的(tomcat环境).但是，当我尝试在服务器环境上运行此应用程序时，出现以下错误.

I have developed a web application using Oracle ADF Essantials. I am able to run this application on tomcat 6.x in my local system. I have the same tomcat 6.x environment on our server . There everything is same(tomcat environment). But when I am trying to run this application on server environment it is giving the following error.

HTTP Status 500 - oracle.adf.controller.ControllerException: ADFC-10001: cannot instantiate class 'com.wip.view.backing.Index'

我尝试了很多修复此问题的方法.但没有得到任何回应.最终，我将本地tomcat 6.x制作为.zip文件，并将其粘贴到服务器上，并从这个新环境中运行我的应用程序，但出现相同的错误.

I tried a lot fixing this isssue. But did not getting anyting. Finally I have made my local tomcat 6.x as .zip file and pasted this on server and run my app from this new environment but getting same error.

我发现浏览器中的网址之间存在以下差异

I observed the following difference between the urls in the browsers

在本地浏览器中 这是我的网址: http://localhost:7777/EasyRUN/faces/index 输入网址后，按Enter会得到相同的

In local browser This is my URL: http://localhost:7777/EasyRUN/faces/index after typing the url when I press enter am getting the same

http://localhost:7777/EasyRUN/faces/index

在服务器上: 这是我的网址: http://localhost:7777/EasyRUN/faces/index 当我按Enter键入此URL后，得到以下内容

On server : This is my URL: http://localhost:7777/EasyRUN/faces/index after typing this url when I press enter am getting the below

http://localhost:7777/EasyRUN/faces/index;jsessionid=06186FB6D5EE4A1243224059F76C1A84?_afrLoop=105719567151&_afrWindowMode=2&Adf-Window-Id=w0

我还尝试了一个只有a.jsf页的测试应用程序.这个程序有同样的问题.它在本地环境上运行，而不在服务器上运行.

And I also tried with a test app that have only one page a.jsf. Same problem with this app. It is running on local environment and not running on server.
