This indicates that you have downloaded Java 7u45 from the Oracle website. Your 'dpkg -l' listing shows that you have also used apt-get to install Java 6b27 (openjdk-6-jre) and Java 7u21 (openjdk-7-jre).

With three installations of different versions of Java, it seems quite likely that they might be conflicting with each other.

I'm not sure how to resolve this conflict. You could start by removing the versions of Java that you aren't using, together with all their dependencies. To do this, you need to use the 'sudo apt-get purge' and 'sudo apt-get autoremove' commands (see this post). Alternatively, you could do a clean reinstall of Ubuntu and then download Oracle Java 7u45.
