The latest stable version of Chrome does not support Java by default. Oracle has a tweak, but it did not work:

I have read in other resources of a combination of tweaks, the above plus one or two more, which may work. Regardless, this does not bode well for Java under Chrome in the short and mid-term. Oracle will either create a Chrome-standard add-on quickly, or Chrome will run Java only with overrides left in for “advanced” users, and will become entirely non-Java-compatible in September:
