66 I java-config bacl top the sun one:
67 The following VMs are avilable for generation-2:
68 1) Blackdown JRE 1.4.2.03 (blackown-jre-1.4.2)
69 2) Sun 32bit JRE 1.6.0.13 (emul-linux-x86-java-1.6)
70 *) Sun JRE 1.6.0.13 (sun-jdk-1.6)
71
72 Started firefox & about:plugins shows no plugins.
73 So I also did eslect java-nsplugin:
74 :
75 Avialble 64-bit Java browser plugins
76 [1] sun-jdk-1.6 current
77
78 Started firefox & no plugins.
79 I traced the symbolic links & manually set it to
80 /opt/sun-jdk-1.6.0.13/jre/lib/amd64/libnpjp2.so
81 which also did not work.
82
83 This is all really weird because I had it working with sun-jdk earlier.
84
85 I also found /opt/firefox/plugins was point to
86 /usr/lib32/nsbrowser/plugins. I repointed this to lib64 & got this
87 error:
88 LoadPlugin: failed to initialize shared library
89 /opt/sun-jdk-1.6.0.13/jre/lib/amd64/libnpjp2.so [...: wrong ELF class:
90 ELFCLASS64
91 from firefox-bin (which I'm using for mail so I can start/stop firefox
92 at will. I suspect that /opt/firefox/plugins is just for firefox-bin.
