开发者_开发知识库I recently upgraded to apex 4.0.1 but when I access 127.0.0.1:8080/apex and login it the page doesn't respong and another thing ... the page is supposed to have some photos but it doesn't appear so when I view the source code of the page and open any of the JS files / photos directories / css files

I get this

404 Not found
Not found
The requested URL /i/css/apex_4_0.css was not found on this server

I have ubuntu 11.04

There's two steps to the upgrade. The first is (mostly) installing the APEX_040000 objects. The second uploads a bunch of files into the database.

Make sure you carried out the second step correctly as documented

It is two steps because, if you are using the Oracle Apex Listener or HTTP Server then you'd put those files on a file system somewhere, rather than in the database.

It sounds like your config file is messed up in some way. Check the configuration to verify that it is directing traffic on port 8080 to the correct directory. Here is a link to how to find the Apache config file and how to read it:

The only other thing I can think of is that the directory does not exist. Maybe it got deleted or moved.
