This could keep me out of potential troubles. Thanks.

Sun does have a 64-bits version of the Java plugin out now, though, although I do not know if it's already packaged into recent 11.x releases (my 11.1 didn't have it yet, as far as I know, although the openjdk cq icedtea version were available as alternatives) -- ****************************************************************** ** Eef Hartman, Delft University of Technology, dept.

With 11.1 there is a crappy Java imitation installed by default, you should get rid of that. But then you can install Sun Java 64 bits and it works fine. It has been like this for at least a year. Before that, there was a 32 bit Sun Java that worked OK, but you needed to install a 32 bit browser.
From: Hendrik van Hees on 19 Jul 2010 18:09 Sun's 64-bit java is buggy (at least for some applications like JaxoDraw (gluon lines) it doesn't work). Use the open java instead.

The openjdk one, I know and I _did_ get rid of it. 11.1 offered three different editions of Java: java-1_6_0-openjdk-1.2_b11 java-1_7_0-icedtea-1.5_b24 (both oss) and the non-oss java-1_6_0-sun-1.6.0.u7 one. The first two are both a bit of beta, but DO offer a 64-bit mozilla/firefox/seamonkey plugin, the sun version at THAT time did NOT. > But then you can install Sun Java 64 bits and it works fine. > It has been like this for at least a year.

That's what I did in 10.3 (the version which was the standard TU version last college year), the O/S (64-bit image) came with the 64-bit firefox, but with the command "firefox32" you got a 32-bit version WITH both Java and Flash plugins installed. Here, now, we're currently only using the 32-bit version (pae kernel) of 11.1, the only 64-bit machines we've got are running CentOS (and aren't used as web browsers, there isn't even a firefox installed on them). But real soon now we'll have to switch to a newer Linux as the newest hardware already got problems with the 11.1 kernel (especially the built-in Intel network adaptor). This could well be 11.3 but the jury is still out..... -- ****************************************************************** ** Eef Hartman, Delft University of Technology, dept.
