If your host architecture differs from LTSP chroot, you won't be able to install Java this way. Chrooting will make the chroot report the host's architecture to the installer, which causes it to download the wrong binary. Generally, chroots should be kept the same architecture as host, but if they must be different, one can still install Java this way if live-boot from the correct architecture media is done and chroot is entered from it.

Plugin
In some cases, the presence of IcedTea Java Browser plugin (OpenJRE implementation) will prevent Oracle Java plugin from working or even being installed.
It is advised to remove all icedtea packages either prior to Oracle Java installation or after it.
In the latter case, reinstallation of Oracle Java might be required to install the plugin properly.
Note: Oracle Java will not work in Google Chrome (since Google changed the plugin implementation system from previous standard) until Oracle issues an updated plugin.
As we see in the the Java Layout tutorial the .jinfo file contains the plugin support. This tutorial only use the Firefox Java support while Chrome and Chromium do not any more support. However here are some known plugin support on Linux:
