Hi

I cannot install openjdk-6-jre on wheezy hdd live due to the following problem:

Package openjdk-6-jre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  openjdk-6-jre-headless icedtea-netx-common icedtea-netx icedtea-6-plugin

Package openjdk-6-jre-headless is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  openjdk-6-jre default-jre-headless icedtea-netx-common icedtea-netx

E: Package 'openjdk-6-jre' has no installation candidate
E: Package 'openjdk-6-jre-headless' has no installation candidate

BTW According the the live manual I've created config/archives/live.list.chroot:

deb http://ftp.ch.debian.org/debian/ wheezy main contrib non-free
deb-src http://ftp.ch.debian.org/debian/ wheezy main contrib non-free 
deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free

and I've the following config/package-lists/my.list.chroot:

task-lxde-desktop openssh-server usb-modeswitch rdesktop iceweasel openjdk-6-jre openjdk-6-jre-headless icedtea-netx-common icedtea-netx icedtea-6-plugin

What's wrong?

greetings
