Like Windows, if you need to browse a webpage with a JAVA Applet, you need to install a JAVA virtual machine. The default virtual machine is Sun's jre (javaruntimeenvironment ), of course, microsoft's Java Virtual Machine can also be installed in Windows. We will not talk about this here. Sudoapt-getinstallsun-java6-jre of course, if you don't care so many M space or need to do JA and Windows, if you need to browse the Web page with JAVA applet, you need to install Java virtual machine, the default virtual machine is Sun's jre (java runtime environment). Of course, microsoft's java Virtual Machine can also be installed in Windows. We will not talk about this here.

Sudo apt-get install sun-java6-jre

Of course, if you do not care about the dozens of MB space or need to do JAVA-related development work, we recommend that you install JDK. JDK contains JRE.

Sudo apt-get install sun-java6-jdk

After the installation is complete, you still cannot view the webpage with the applet, because the browser plug-in has not been configured. Here we take FIREFOX as an example:
Cd to the/usr/lib/jvm/java-6-sun/jre/plugin/i386/ns7 directory, you will find a file named, this is a dynamic link library (dll) file in linux. Regardless of the number of shortcuts, copy the shortcuts to the plug-in directory of FIREFOX.


Sudo chmod + w

Sudo chmod + w/usr/lib/firefox/plugins


Enjoy it!
