APEX Listener stop responding after some time

After some time or server restarts i tried to get APEX page live. After trying to access login page i got error:

"Requested url

http://apextest:7001/apex/f is currently unavailable."

I found that the problem is when APEX listener is started it created file named apex-config.xml in current TEMP file in Windows.

There are two solutions.

First one is to go to page :

http://wlstest:7001/apex/listenerconfigure and re-instantiating APEX listener.

Another solution is to follow Oracle manual for Apex listener and unzip apex.war, edit web.xml file so param-name config.dir is enabled, and enter any value (C:\apex_config\...). Zip everything and redeploy apex.war and restat apex web aplication (Weblogic server component).
