Hello, i plan to use a Raspberry Pi + Firefox to remote display a dynamic webpage. so i installed Ubuntu-mate in Raspberry Pi 3 and got everything updated. when i open the webpage, it said, i should install the jre at least version 1.7. i used java -version checked the version is 1.8.0. then i believe the environment is fine i only need to link the file libnpjp2.so to firefox plugins. but i can’t find this file from path /usr/lib/jvm to path /usr/lib/firefox/plugins. finally i even can’t find the file.
so i did another two solutions:
-
Download the JDK8u in Oracle pages and reinstall the JDK, then i found the file and use ln to link to path /usr/lib/firefox/plugins. but when i open firefox again, the page still can’t work and use about:plugins, i also can’t find the plugs.
-
i deleted the whole system and flash it again on the tf card. then i use IcedTea to satisfied firefox for java plugins, and finally i can see IcedTea in about:plugins but the java version is 1.6. what i need is at least 1.7.
unbelievable, anyone who can help on this java plugins problem in firefox?
