No compatible Java* Runtime Environment (JRE) --- But it is installed!!!

[loraulethotmail_com]

I m with Ubuntu 9.04 and I am getting this error in Step no 4 of the installation of Intel Fortran:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Step no: 4 of 7 | Installation configuration - Missing Optional Pre-requisite
--------------------------------------------------------------------------------
There is one or more optional unresolved issues. It is highly recommended to fix
it all before you continue the installation. You can fix it without exiting from
the installation and re-check. Or you can quit from the installation, fix it and
run the installation again.
--------------------------------------------------------------------------------
Missing optional pre-requisite
-- No compatible Java* Runtime Environment (JRE) found
--------------------------------------------------------------------------------
1. Skip missing optional pre-requisites [default]
2. Show the detailed info about issue(s)
3. Re-check the pre-requisites

h. Help
b. Back to the previous menu
q. Quit
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After seeing this, I downloaded jre1.6.0_17 from http://java.com/en/download/manual.jsp
and I believe I did it fine:

raul@ubuntu:~/usr/java$ ls
jre1.6.0_17 jre-6u17-linux-x64.bin

But I come back to install Intel Fortran and I still get the same error:

--------------------------------------------------------------------------------
Missing optional pre-requisite
-- No compatible Java* Runtime Environment (JRE) found
--------------------------------------------------------------------------------

What am I doing wrong?

Thanks,

Raul.

The previous release of ifort installer would give this complaint about most versions of JRE, including the current one. You could continue the installation. Also, before you install Sun JRE, you must remove any symlink /usr/bin/java -> so that the JRE installation can make this symlink point to itself. Recognition of JRE is required only to make idb work; any problem with it can be corrected after installing ifort.
