Problème Java lors de l'ouverture Matlab

Bonjour,

Je viens d'installer matlab, sauf que quand je veux le lancer, j'ai le msg suivant :

-----------------------------------------------------------------------------------------------------
Warning: Cannot locate Java Runtime Environment (JRE) . . .

         1. Either a correct JRE was not available for redistribution when
            this release was shipped, in which case you should refer to the
            Release Notes for additional information about how to get it.

         2. Or you have tried to use the MATLAB_JAVA environment variable
            to specify an alternate JRE, but MATLAB cannot find it.  Please
            run 'matlab -n' to determine what value you are using for
            MATLAB_JAVA and fix accordingly.

Ducoup, j'entre en session sudo, et la, le problème de licence ne se pose plus.

Je rentre la ligne de commande suivante :

export MATLAB_JAVA=/usr/lib/jvm/java-6-sun/jre/

et j'ai la (j'ai bien cru que ça allait marcher) j'obtiens ceci en relançant matlab:
