From the Java FAQ section.

Google announced in September 2013 plans to remove NPAPI support from Chrome by "the end of 2014", thus effectively dropping support for Silverlight, Java, Facebook Video and other similar NPAPI based plugins. Recently, Google has revised their plans and now state that they plan to completely remove NPAPI by late 2015.

As of April 2015, starting with Chrome Version 42, Google has added an additional step to configuring NPAPI based plugins like Java to run.

See the section Enabling NPAPI in Chrome Version 42 and later.

If it is still not working, check if the Java plugin is installed in Chrome. Type in the address bar: chrome://plugins/.

If the Java plugin is not listed there checkout this Stackoveflow thread How to configure Chrome's Java plugin so it uses an existing JDK in the machine.
