Hello World runs with errors

Question

I am having trouble with the Hello World program in JDeveloper RUP7 setup.
And I have searched these forums, but no threads describe this exact issue.
When I run the Hello World, the first page appears fine, with all the links showing.
However, when I click on any of the links in the page, then I get an error,
and the page dumps me to our main Applications Login screen.
The error I get (after clicking on a link) is:
Unexpected URL parameters have been detected and will be ignored
And the link I click on in Hello World application is:
http://scottma09.corpusa.napole.local:8988/OA_HTML/OA.jsp?
OAFunc=FWK_TOOLBOX_HELLO&
OAPB=FWK_TOOLBOX_BRAND&
OAHP=FWK_TOOLBOX_TUTORIAL_APP&
OASF=FWK_TOOLBOX_HELLO&
transactionid=1255486469&oas=kIYCU8z8RLu95eOyqIqWaw..
Any advice is greatly appreciated.

Answer 1

Thank you both for your input.
I was already using my Oracle user acct, which had been setup properly.
But when installing JDeveloper, I did not see any mention of:
Tools -> Preferences -> Embedded OC4J -> Default Local IP Address (Recommended)
Selecting that option solved my problem.
Also, I had been investigating the advice in this other thread, but it did not help:
Unexpected URL parameters have been dete
