OAS 10.1.3 preview - Unable to launch em

After installing OAS 10.1.3 preview, I am unable to launch em. I am getting the following error

404 Not Found
Resource /em not found on this server

Surprising thing is when I try to launch the em console using 7200 port, I am able to get the console page. Provided I give localhost as my host name.


Looks like its a bug.

This is what my install/readme.txt says

The installation of Oracle Application Server 10g was successful.

To access the Oracle HTTP Server:


To access Oracle Enterprise Manager Application Server Control:

    Hi --

    You can find the HTTP port allocated to the Oracle HTTP Server by using the opmnctl utility.

    Try this:

    $ORACLE_HOME/opmn/bin/opmnctl status -l

    This should spit out a table showing all the managed processes and also the ports they are currently asssigned.

    Look for the HTTP_Server entry and the corresponding HTTP port it is using, then use that as the server:port entry to access EM.

    Typically on Windows we default to port 80 and on the *nixes we default to 7777.  If those ports are not available at install time then the installer will increment the value sequentially until if finds a free port.
