T3://127.0.0.1:7101: Destination unreachable; -- On jDeveloper 11gR1

Question

I am new to weblogic, and have just installed Oracle Express, WLS, jDeveloper.
After running through the tutorial on 'Building a Web Application with JDeveloper 11g Using EJB, JAP, and JavaServerFaces', following all steps to the letter, I am able to make the DB connections alright, start the integrated server, but once I try running the HRFacadeBean in step 18, but it errors out.
It seems to me that the issue with recognizing the t3 protocol.
I have checked that 127.0.0.1:7101 is up and running as I get the welcome screen when I go to it and there are no errors listed on the server console screen in jDeveloper, but I get this trace in the log:

Hi,
I guess the problem is with below information but I do not know from where they came!? maybe in the jdeveloper you have set the proxy or maybe your localhost is not bind to 127.0.0.1 and you must use your computer name.
Dhttp.proxyHost=proxy.ulalaunch.com -Dhttp.proxyPort=80 -Dhttp.nonProxyHosts= -Dhttps.proxyHost=proxy.ulalaunch.com -Dhttps.proxyPort=80 -Dhttps.nonProxyHosts= oracle.HRFacadeClient
