I found the solution. You need to do two things.
At first run the server from JDeveloper. Go to Administrative console:
http://your.current.address:7101/console. Login with credential.
Choose Servers from the tree of Domain Structure, then click on the
server you need to configure and insert your IP in the textbox beside
Listen Address. Log out.
Stop the server from JDeveloper.
Go to Application Server Properties from JDeveloper. To get this, go
to View->Application Server Navigator. Open the tree Application
Servers and right click on the Server you are running and want to
configure. In my case it is with name IntegratedWeblogicServer. Choose
Properties from the context menu. Go to Configuration Tab. Enter your
IP in the Weblogic Hostname field. Press ok.
Run your server again and run your application. Browse for URL
http://new.address:7101/AppName from different machine connected in
same network.
That's all. :)
I did all of that but I can“t still connect but If I only write the IP on the browser it says: IT WORKS! but not with the whole url, the server is a windows server 2008 R2 64bit, please help
FORGET IT! I FIXED IT: I ADDED A NEW INBOUND RULE(Control panel), ALLOWING THE PORT 7101 AND 7102 ! TCP, THANKS ANYWAYS! HOPE MY info helps
