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'

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.

I observed the following difference between the urls in the browsers

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

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

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.

Please help.

Thanks in advance. Thank you very much. Please help.

Thanks for you help. I found the solution. The problem was I have jdk1.7 on my local system and on server I have 1.6. Thats why I faced that problem. Now on server also I have installed 1.7 my application is running successfully.

Thanks a lot for your help. Thank you very much.
