the libnpjp2.so in this location is:
-rwxr-xr-x 1 root root 77510 2011-07-19 10:57 libnpjp2.so
so it should be an executable, not a symlink pointing to other locations.

but this is not what you specify here, it is higher up in the directory
hierarchy. Maybe my installation has a different structure?

java version "1.5.0"
gij (GNU libgcj) version 4.3.0 20080428 (Red Hat 4.3.0-8)

I have already removed everything from my /home/<user>/.mozilla
I start suspecting that the problem may be the internet banking logon
I continue Googling for answers, and I found one that made me suspect
this. I still keep firefox-3.5.4, and I found a pervious plugin that I
symlink from its plugins directory, which looks like this:
lrwxrwxrwx 1 root root 76 2011-10-09 12:21 libjavaplugin_oji.so ->
-rwxr-xr-x 1 root root 15824 2009-10-16 18:02 libnullplugin.so
[par at localhost plugins]$
In fact I now manage to log on to the internet banking application from
But newer versions of firefox seems not to function using this plugin.
I am not happy with this solution, but it is better than nothing. It
means that I have a (sort of) functioning bank id, and this also comes
to use in other settings, fx. credit card payments. This is a secure way
of identifying yourself electronically, and I cannot live without it, it
I also discovered something else:
The java in /usr/java/jre1.6.0_27/bin/ responded like this when I tried
to start it:
[par at localhost bin]$ ./java
Error occurred during initialization of VM
This error message is identical to the one I get in the terminal window
when Firefox goes down after the attempt to logon to the banking
