To understand this tutorial, I assume that you are already aware with Spring MVC and how it works. I will demonstrate here a simple Ajax call in Spring MVC where form data are posted and sent to the controller. The output of the ajax call is plain string text.
NPAPI support by Chrome
The Java plug-in for web browsers relies on the cross platform plugin architecture NPAPI, which has long been, and currently is, supported by all major web browsers. 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.
After upgrading the earlier versions of Chromium browsers to later versions greater than 42, internet users have started complaints that the JAVA plugins are not supported by chrome. After a bit research, found that chromium browsers have disabled NPAPI plugin-in on their latest versions. The deprecation of NPAPI plug-in caused the JAVA plugins to be blocked in Chrome.
