Greeting
I am facing an error that when I starts dbca, it shows an error message.

here is part of the log file (hs_err_pid24111.log)

In the first picture, dbca seems to use JAVA 1.5, But I installed JAVA 1.7.

My computer is :
32 BIt, Oracle LInux 6
connected in line sharer (port forwarding 8080, 1521)
I am newbie to Linux and Oracle.
And I really want to install Oracle Enterprise Edition for study
Anyone knows the solution ?
Thank you
