I am running ubuntu on an AMD 64 bit system. I have installed firefox as part of the distribution. I need to run a 32-bit java app with the 32-bit jre plugin. When I install the 32-bit jre plugin per http://www.oracle.com/technetwork/java/javase/manual-plugin-install-linux-136395.html the java plugin is not found (I don't see it listed in the Add-ons Manager and http://www.java.com/en/download/installed.jsp cannot verify it) however when I install the 64-bit jre the plugin is found and works correctly. Is there a way to install the 32-bit jre plugin given my current sysem configuration? Thanks
