SQL Developer

I have a beta version of sqldeveloper installed on a Linux Red Hat Ent Ed Update 4 Server with Oracle 10g 10.2.0.2.0 EE and have been using it for a few months with no problems.

I have downloaded the new release "Oracle SQL Developer for Multiple Platforms"
unzipped it into a new directory off of "/". I had a JDK install with the old version , because the old, beta version worked.

How ever when I try it start the new "Oracle SQL Developer 1.1 (1.1.0.23.64)
" version I get this error:
[oracle@localhost sqldeveloper]$ sh sqldeveloper.sh -J-Dsdev.insight=false

I have tried:

$sh sqldeveloper

and the above command.

What is wrong?

thanks.

As a sidebar I tried to get the rpm version of linux to work, I could do a

$rpm -Uvh *.rpm

and it would install. But nothing changed with my old beta version. What did I do wrong?
