To get it working, you just have to do what they say here - 32-bit java is the keyword here. But there might be other way, read on. > [ykarant@ahprc3 ~]$ java -version > java version "1.6.0_24" > OpenJDK Runtime Environment (IcedTea6 1.11.3) > (rhel-1.48.1.11.3.el6_2-x86_64) > OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode) And this is 64-bit openjdk, not what they meant. > and although firefox reports that the jre plugin is enabled > (that is /usr/lib/mozilla/plugins has libnpjp2.so as a soft link to > the correct file from the above URL source ( > /usr/java/default/lib/i386/libnpjp2.so ) > [again -- 32-bit version for Java applet and Java Web Start support > we need] and is reported by firefox as enabled) No, you mistunderstood what they meant (no wonder, as they forgot about openjdk's existance, which complicates things). They are talking about *oracle* java. Oracle java didn't support 64-bit firefox plugin in the past (I'm not sure if it does now), which is why you'd have to use 32-bit browser with 32-bit plugin - and, of course, 32-bit java to go along with that. OpenJDK 6 is completely different beast; java plugin packaged with SL6 (icedtea-web package) indeed supports 64-bit browsers. So, your first option is sticking to SL openjdk and 64-bit versions. Make sure you have icedtea-web package installed, and use *64-bit* firefox. The java plugin should work, the site in question might or might not (some tend to dislike openjdk, especially openjdk6). All packages are in SL, you don't need to install anything else. Second option is to follow instructions on that site. For that, you have to download & install 32-bit java 7 from oracle site, install 32-bit version of firefox (there is one in SL, too) and the site should work for you. > the java in fact does not run.

Well, discovering who to blame for that would be OT, I just hope you'll get the site working! I suggest you to try with stock openjdk first and go for oracle 32-bit versions only if you discover some problems. -- Vladimir
