问题
I've been following this Video tutorial: https://www.youtube.com/watch?v=_xTfRIRPsNU to run a OAF page in JDeveloper in Oracle E-Business Suite R12
As shown in the video I made a successful database connection from JDeveloper to Oracle EBS through the correct DBC file, I opened the sample projects I got with JDeveloper and set all necessary Runtime Connection information. After rebuilding the included 'tutorial' project, I reached the final step, ie, running 'HomePG.xml', but I'm unable to run the page and I'm getting the following in the message log:

and the page opens as follows:
Note: For above execution, under Embedded OC4J Server Preferences->Java Compiler-> Compiler: ojc, Bin Directory: /home/user/jdev10g_install/jdevbin/jdev/bin/
Changing the Bin Directory to the JDK's bin, didn't do any good and produced a similar error page with the difference : 'ojc not found under /usr/lib/jvm/jdk1.5.0_22, specify the correct location of ojc in server.xml using the tag '
Then I tried changing the following in Java Compiler-> Compiler: javac, Bin Directory: /usr/lib/jvm/jdk1.5.0_22/bin
And produced a different message log:

And page error:
My Oracle EBS version is 12.2.4 which I'm running through VirtualBox 5.1 for Linux hosts. My JDeveloper version is 10.1.3.5, which is the compatible version for the above mentioned Oracle Apps version.
I want to know what the reason might be that I can't run the page. I've been at this for days now. Help would be greatly appreciated.
