How to install Java 7 on Ubuntu (update 1.7.0_25)

Unfortunately JAVA is a necessary evil for many online banks. Then you need it to get access to Santander, Caixa and other Brazillian banks.

To install it execute the procedure explained in this page: http://www.webupd8.org/2012/01/install-oracle-java-jdk-7-in-ubuntu-via.html Basically we need to execute:

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java7-installer

You need more two steps to get java plugin working on your web browser (Firefox):

$ sudo ln -s /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libjavaplugin_jni.so /usr/lib/mozilla/plugins/libjavaplugin.so

$ sudo ln -s /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/libnpjp2.so

That is it. I hope you still praying for the day that we don’t need to use Java in our browser.
