I use a java app (mercury messenger, to be specific), and the last time I tried to use the openjdk with it, some months ago, I experienced some issues. Hope it's fixed in the latest openjdk release.

easy enough to download java from oracle if openjdk doesn't work for you

Yes, that's what I used to do some years ago (it's a bit of a hassle, though).

Just to confirm,
in my squeeze install, apt still reports sun-java6 packages as available.

- any risk using sun-java6 as of today or I should go to openjdk-6 immediately?
- am I correct to say that icedtea6-plugin is required in place of sun-java6-plugin?


Thank in advance for the clarification.

See #645881 - critical update 29 available - Debian Bug report logs - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=645881

I would either switch to Openjdk or download the current java 29 from Oracle.

craigevil, thanks for the link and advise.

1. Any advise (or link) on how to install sun-java on Debian and

2. How to remove sun-java (so as to install) when a new version comes out?

3. Installed and tested openjdk at https://www.java.com/en/download/testjava.jsp and got a message that it is only at update 18 (earlier than the outdated sun-java6 in non-free) .


Thanks in advance for the help.

You need to download the self extracting package from Oracle website and follow the instructions. However, being a manual install, I would extract the package inside /opt (instead of /usr/java), and make a symbolic link to /opt/jre1.6.0_29/bin/java inside /usr/bin. As for the browser plugin, you need to make a symbolic link to /opt/jre1.6.0_29/plugin/i386/ns7/libjavaplugin_oji.so inside /usr/lib/iceweasel/plugins (in case you're using iceweasel, otherwise it should be in the plugins directory of the browser you use). Actually, the instructions on the website talk about making the symbolic link to <Java installation directory>/lib/i386/libnpjp2.so, but as far as I know, the the browser plugin library is libjavaplugin_oji.so, so I'm a bit confused (you can try each one separately to see which one works).

As for the uninstallation, basically you have to delete the directory 'jre1.6.0_29' from /opt, delete the 'java' sym link from /usr/bin as well as the plugin lib sym link from /usr/lib/iceweasel/plugins.

If this explanation is too confusing, please, say so and I'll post how to do it step by step.

Regards.

I juest tested, and indeed, the correct plugin lib is "<Java installation directory>/lib/i386/libnpjp2.so", as the instructions say.
