Java errors could simply be resolved by performing a new installation of the Java Runtime Environment because these errors are strictly related to the runtime or its libraries. The reason these errors appear is due to the fact that other applications mess up the paths to libraries, registry entries and so on. You should go to Control Panel > Add & Remove Programs and remove the current version of the Java technology then download a new package from the official website and perform a new installation. Plus, a restart will be mostly required for the settings to take effect.
